I got one from Amazon less than $15.00 it does all of what you did plus live data that tells me rpm, mph, coolant temp aka temp Guage, O2 sensors, EVAP, IM readiness, and has a seprate button to quickly access battery voltage, seprate button for stored codes. I'm able to delete codes aswell best purchase made
need to know, OBD plug are connect to ECU car computer, cheap OBD scan plug may burnt it , shouldn't do it yourself , you can tell the dealer or the seller need to do a check in a workshop, let them check the car, they will scan it for you, and at australia you can call racv come to your place to do a full check over, is cheap and the best is if after you bought the car within sometime ,sorry forgot how long, they will pay for fix even need the whole engine., it happen before in my workshop.
This is exactly what happened to me . I bought a Mitsubishi L200 when I took it to my local garage for its annual inspection they told me the ABS light was not coming on . When I removed the main panel in front of the instrument cluster some screws holding the instrument cluster down were missing. I removed the instrument cluster to find the ABS bulb and holder had been removed . After plugging in a scan tool I found fault codes for the front wheel sensors . As mentioned in this video the ABS light should always come on momentarily when starting the ignition.
@@CarRepairsMadeSimple it does I started buying and selling cars that have little problems I'll fix em up and sell them but a lot of people erase codes 🙄
Some may say incomplete because the car had an issues before and the seller or dealer got it fixed before putting it on sale. That would be a pending code, and for it to go away the car must be driven for some hundred miles.. and I would assume the dealer or seller would not want to do that themselves because it would take some value away by increasing the mileage.. is that right?
That is true to a point, but there are far too many scammers out there to take a chance. Plus, if you’re a mechanic working for a dealership, they would know vehicles have a specific driving sequence that can be followed with varying speeds, stop and goes, etc to complete these system checks very quickly and reducing the mileage put on a vehicle when testing it. Besides, would you want a vehicle that wasn’t tested to ensure it’s working properly? Another reason to not buy a car with pending codes and incomplete system statuses.
I would have liked to know this information just before I bought my miata nc since it came with error code u0100 and blows my engine fuse everytime i turn the key to on position, now I am without a car, without money and stuck in a job that i don't get paid enough to repair it and get another job 🙃
Plz help - There are no INC’s in “Since DTC cleared”. But there are some INC’s in “This drive cycle”. So is this normal. Is the vehicle in good condition ?? Thanks for your help man 👍🏻👍🏻
that should be okay. "This drive cycle" gets reset every time you turn off the car, and all of the IM readiness systems can’t run there cycle in a single drive. It’s the other menu you want to be concerned about. It shows long term information and will tell you if anything has recently been reset.
@@CarRepairsMadeSimple You are welcome. I also have the small OBD ll with no lead, it's around 3-4 inches long.

Check out my video for more information! ua-cam.com/video/SjYVD2WCrCM/v-deo.html It won't help your mpg but it's still important to do. Also by the sound of it, you don't do much driving. Are you using premium gas? and do you do mainly city driving and/or drive in lots of stop and go traffic? Those things could also reduce gas mileage. It's hard to say when I don't know your driving habits or the history of the car, but I hope I could help!
3:54 The scanner only works with the ignition on., so it shouldn't make a difference. MIL stands for Malfunction Indicator Lamp aka check engine light. So it only will say on if there's a code.
In terms of what? If the CEL was reset very recently, then the I/M readiness systems will not be set to okay status. It can take anywhere from a couple drives to a full week until those systems are all complete, so that part can be inconsistent.
@@vince2113 that should be okay. That gets reset every time you turn off the car, and all of the IM readiness systems can’t run there cycle in a single drive. It’s the other menu you want to be concerned about. It shows long term information and will tell you if anything has recently been reset.
I got a quick question tho, can that obd2 scanner also read how many miles the car actually has, because you know with all the mileage roll back fraud situations…
No it doesn't show how many miles are on the vehicle or if there was a mileage rollback. However, a carfax report will show you this. It will give a detailed list of history records including the service performed, the date, and the mileage. If the odometer on the vehicle is less than the last recorded mileage, then you'll know they're commiting mileage fraud.
You want to ensure that you do see a check engine light illuminating when you first turn the ignition to the car on. This way, you can ensure the light is working. It's important for this light to work so when a problem arrises, it will illuminate when the car is running to let you know something's wrong.
@@NateVega-jm3zf simply resetting the light isn’t going to fix the problem. The light will simply turn back on within a week most likely. Only reset the light after you’ve made an attempt to fix the problem. There are some things that can cause a check engine light but are barely noticeable, such as a loose gas cap. But nonetheless, it’s still important to fix any issue causing a check engine light to turn on to ensure no additional damage or problems arise and for your car to work as efficiently as possible
so, i bought one of these and ran it. everything looks good, no stored or pending codes. mil status is off and everything says ok or n/a. except for the evap system mon. which says inc. i haven’t been able to get a clear answer but what exactly does this mean???
Incomplete simply means the computers self analysis for the evap system hasn’t completed yet. This test can take anywhere from a few hours to a few days to complete until certain driving cycles have been met for the car to fully analyze itself. Incomplete in itself isn’t a bad thing, however, it is an indicator that the check engine light codes were very recently cleared either by using a tool like this or by disconnecting the battery.
@@CarRepairsMadeSimple thanks for replying! i turned off the car shortly after and waited a bit to test again. the second time, the evap system mon. had ok next to it and everything else looked good. idk why it changed in such a short time but i just wanted to make sure the previous owner did not clear anything off.
Hi, I bought the AD310 scanner for my Toyota Corolla 2005 and I would like to know if the device is compatible with my vehicle, because the communication between the computer and the AD310 is not established. I have two other vehicles and I had no problems with them. Could you please tell me if the AD310 is compatible with the Toyota Corolla 2005. Thank you.
For reasons that I do not know, the Ancel AD310 is not compatible with early model Corollas. Ancel does make a Toyota-specific scan tool, the TD700, but it's $95 on eBay. Maybe shop around if that's too expensive.
Please help, I purchased a used car and didn't check codes, I checked codes after buying and it has 3 codes but the dealership says the codes are just from memory storage and not active, he said it was a problem the car once had but is resolved, is that true? Or is the car likely going to give me the problem? I checked drive monitors and they are all ok and complete. I am taking a long drive this weekend to see if it triggers the car check engine light which is off. The car is used but does have a 3 month powertrain warranty which would include the codes I found when scanning. I'm wondering if I should just sell and not deal with it
It is possible for codes to not go away without clearing them manually. Why the dealership didn’t clear the codes after supposedly fixing them is questionable. Warranties also mean nothing to me. Car dealerships will do anything and everything to avoid having to fulfill a warranty. If the codes have not been legitimately fixed, they’ll come back usually within a few days to a week, and you can make your decision from there.
sorry idk why that link wouldn't work anymore. Yes the Ancel AD410 would also work fine and can be used to look for Check Engine codes and I/M readiness systems. Otherwise, just type in Ancel AD310 on eBay and a bunch come up.
Unfortunately there isn’t any any tool that can detect mileage rollback, only tools to change the mileage. This specific OBD-ii scanner shown in this video cannot do either. If you are suspicious of mileage fraud, you can get a car fax which will show the service history and mileage over time. If the current mileage is lower than what was previously recorded at an earlier date, you’ll know there was a mileage rollback.
@@CarRepairsMadeSimple unfortunately we scanned it and it didn’t tell us it was inc so we bought it and then after about 100 miles the check engine light came on for cat converter but the timing just seems too suspicious. It’s a 99 Camry too so I should’ve known when there were no codes at all
@@mkaelacarat there can sometimes be a small timeframe until a CEL will be triggered, even after the readiness systems all say OK. If you got it from a used car dealership, you might be able to return it still if it's not too late. Or sometimes they'll even pay for any repairs needed within a certain timeframe after purchase. If you bought it privately, not a whole lot you can do other than fix the problem. Only so much we can do to avoid scammers.
Scammed this week on a Prius with blown head gasket. Pos craigslist dealer reset the check engine light. Text him later that day I swear the check engine light was off. Out 2500 for a engine swap.
Dang I hate hearing stories like this. Buying cars is so sketchy. My parents got screwed over buying a jeep, and it motivated me to make this video. I recommend doing this OBD-II check and getting a car fax to everybody when buying a car.
This particular unit cannot detect mileage tampering. I’m not sure if any unit can for that matter. But what you can do is get a CarFax or look at the vehicles service records if the owner keeps those and verify the mileage lines up with its history.
When I go to read codes before I drove vehicle there were 5. I cleared codes and drove the vehicle.check engine light came on but only 2 codes showed up. Do I discard the previous codes,thanks!
Mike Johnson It depends. Some codes may take longer than others to reappear, sometimes days and even weeks to show up again. Also, some codes won’t go away on their own even if the issue itself was fixed. So if you know the issue was fixed you could discard those codes. If there were codes to begin with but nothing was done to the vehicles, I would not discard them and consider the fact there’s a good chance they could come back again. But for now, I would just address the immediate codes that came back, and hopefully that could fix the potential issue of the other codes too, since a single problem could trigger multiple codes.
@@CarRepairsMadeSimple hey man thankyou for the reply,at first I used the mechanic on duty,s simple code reader it said 0088 .then used mine and pulled up all existing codes,PDF,d them then cleared codes ,drove it and came up with 2018-1 and 2016-1 After some research I'm going to test fuel return rail injector differential,test pressure control valve,measure pressure before and after filter,test cascade overflow valve, fuel solenoid pressure during starting and during cranking unplugged, check fuel pressure set point vs fuel pressure.unplug quantity control valve in the Cp3 and chk pressure default, pump pressure generation test using the drb3, check for fuel leak in one of injector lines, fuel line leak, fuel line between tank and low pressure pump. I really don't know the meaning of most of these items but I can figure it out. What you think man?
Mike Johnson it definitely sounds like there’s a lot going on and you’re on the right track. Idk much about your situation, but usually whenever I get a code, I enter it into autocodes.com and that gives a pretty good write up on what’s causing it and how to fix it. Then I’ll search the forums if I need additional information. I’d start with the 2 codes that came back for now, and only address the others if they come back after fixing your initial 2 codes and problems. I hope that helps some.
@@cfsouthern It could be. A vehicle can appear to drive fine with a lot of codes, such as an evap leak code, but they're all bad and will lead to more problems down the road. Check the manufacturing date on the battery to confirm that a new battery was actually put in.
This video is bullshit i went to buy a car and 2 of the oxygen sensors said incomplete so i left after watching this video but when i came home i tried to use the tool in my car and it sais the same thing. incomplete and i never had check engine light in my car for over a year and i drove over 30k on the last year
I/M Readiness and Check engine lights are two different things. I/M Readiness is a series of self-monitoring systems that take multiple driving cycles in order to "monitor" itself and determine if anything is wrong. So if any of them still say incomplete, that simply means the car has not been driven enough since the last time the codes were cleared or since the battery was last disconnected. This can take anywhere from hours to weeks. A check engine light states something abnormal has been detected during the self-monitoring. So I think you're looking at it backward. If it says incomplete, there really shouldn't be a CEL yet. And that's the whole point of the video. People try to hide the CEL from buyers by erasing the code with a scanner or disconnecting the battery. So since you can still see an incomplete status, that means the CEL was cleared recently.
@@CarRepairsMadeSimple means should i stay away from that car or should i go with it?my car say the same thing incomplete but last time my check engine was on over a year ago and i drove over 30k miles already
Yassine yassine On your car, have you recently cleared the codes or taken it to a shop for repairs where the battery could have been disconnected? Or has there maybe been a dead or replaced battery? The 30k miles won’t matter if the system was reset somehow. But in regards to the car you’re looking to buy, since it has some incomplete system status’s, I recommend not purchasing that car.
Yassine yassine yah that would probably explain why your oxygen sensor systems say incomplete since you had to disconnect your battery to replace it. It’s a bit longer than normal for them to still say incomplete, but not unheard of. And who knows, maybe the other guy coincidently replaced his battery too. The unfortunate part now is you don’t know if there were any codes. You could take it for a test drive and with your best judgement if you think it’s a good car, go for it. Otherwise, there are tons of other cars out there to buy.
Im sad how many sellers do this. I've went to 5 car lots in the last two weeks and 4 out of 5 cars had check engine codes that were reset. Only one seller acknowledged they tried to fix a problem and reset the light. The other sellers act like they didn't know anything. Some very shady sellers out there.

Good luck!
@@CarRepairsMadeSimple all great points of information !!!! We have not yet found a vehicle that I want to make an offer on and just today ordered the OBDII scanner, but will keep all your good advice in mind when we do find something.....thank you again sir ......

What a great video I came across. Thanks!
You’re very welcome! Glad it was helpful!
need to know, OBD plug are connect to ECU car computer, cheap OBD scan plug may burnt it , shouldn't do it yourself , you can tell the dealer or the seller need to do a check in a workshop, let them check the car, they will scan it for you, and at australia you can call racv come to your place to do a full check over, is cheap and the best is if after you bought the car within sometime ,sorry forgot how long, they will pay for fix even need the whole engine., it happen before in my workshop.
Great vid. You already saved me money.
Thank you! I'm glad my videos have been helpful!
Thanks man, Its really helpful. Thank you so much.

Best video I’ve seen on the is topic! 👍🏻👍🏻
Thank you!!
This is exactly what happened to me . I bought a Mitsubishi L200 when I took it to my local garage for its annual inspection they told me the ABS light was not coming on . When I removed the main panel in front of the instrument cluster some screws holding the instrument cluster down were missing. I removed the instrument cluster to find the ABS bulb and holder had been removed . After plugging in a scan tool I found fault codes for the front wheel sensors . As mentioned in this video the ABS light should always come on momentarily when starting the ignition.
Sucks to hear that happened to you. Hopefully, more people can learn these simple tricks to avoid scammers like those.

@@CarRepairsMadeSimple it does I started buying and selling cars that have little problems I'll fix em up and sell them but a lot of people erase codes 🙄
Very helpful. Thank you.
Glad it was helpful! Thanks for watching!
Great info
Some may say incomplete because the car had an issues before and the seller or dealer got it fixed before putting it on sale. That would be a pending code, and for it to go away the car must be driven for some hundred miles.. and I would assume the dealer or seller would not want to do that themselves because it would take some value away by increasing the mileage.. is that right?
That is true to a point, but there are far too many scammers out there to take a chance. Plus, if you’re a mechanic working for a dealership, they would know vehicles have a specific driving sequence that can be followed with varying speeds, stop and goes, etc to complete these system checks very quickly and reducing the mileage put on a vehicle when testing it. Besides, would you want a vehicle that wasn’t tested to ensure it’s working properly? Another reason to not buy a car with pending codes and incomplete system statuses.
@Incin3ration good point about the ensuring the part it's working OK.. some wouldn't even do that and just sell you a crappy car
I would have liked to know this information just before I bought my miata nc since it came with error code u0100 and blows my engine fuse everytime i turn the key to on position, now I am without a car, without money and stuck in a job that i don't get paid enough to repair it and get another job 🙃

Plz help - There are no INC’s in “Since DTC cleared”. But there are some INC’s in “This drive cycle”.
So is this normal. Is the vehicle in good condition ??
Thanks for your help man 👍🏻👍🏻
that should be okay. "This drive cycle" gets reset every time you turn off the car, and all of the IM readiness systems can’t run there cycle in a single drive. It’s the other menu you want to be concerned about. It shows long term information and will tell you if anything has recently been reset.

@@CarRepairsMadeSimple You are welcome. I also have the small OBD ll with no lead, it's around 3-4 inches long.

Would you have any knowledge on that subject?
Abdul Karim D my overall recommendation would be no as they have been known to drain batteries
Nice job with the video. Any idea what Monitors N/A means? On mine it shows as Monitors N/A 2.
N/A mean not applicable. The scanner is simply searching for a monitor that doesn’t exist in your vehicle.
Nice job.
Thanks for the post and appreciate the help . How much miles you will get for a full tank ?

@@chenupy77 I wouldn't recommend flushing it. If the fluid looks dark from the dipstick, I would recommend doing a drain and fill. Check out my video for more information! ua-cam.com/video/SjYVD2WCrCM/v-deo.html It won't help your mpg but it's still important to do. Also by the sound of it, you don't do much driving. Are you using premium gas? and do you do mainly city driving and/or drive in lots of stop and go traffic? Those things could also reduce gas mileage. It's hard to say when I don't know your driving habits or the history of the car, but I hope I could help!
Mil on could also mean your ignition is on when doing the scan, did you have the ignition off when checking this?
3:54 The scanner only works with the ignition on., so it shouldn't make a difference. MIL stands for Malfunction Indicator Lamp aka check engine light. So it only will say on if there's a code.
You're the best!
Thanks! I’m glad my video was helpful!
How accurate is the I/M Readiness ?
In terms of what? If the CEL was reset very recently, then the I/M readiness systems will not be set to okay status. It can take anywhere from a couple drives to a full week until those systems are all complete, so that part can be inconsistent.
Nice job sir
Thank you! And thanks for watching!
AWESOME!!
What if it says INC under IM readiness but under (THIS DRIVE CYCLE) is that okay? I noticed comp component says INC under This drive cycle.
@@vince2113 that should be okay. That gets reset every time you turn off the car, and all of the IM readiness systems can’t run there cycle in a single drive. It’s the other menu you want to be concerned about. It shows long term information and will tell you if anything has recently been reset.
@@CarRepairsMadeSimple okay thanks for letting me know. Appreciate the video.
I got a quick question tho, can that obd2 scanner also read how many miles the car actually has, because you know with all the mileage roll back fraud situations…
No it doesn't show how many miles are on the vehicle or if there was a mileage rollback. However, a carfax report will show you this. It will give a detailed list of history records including the service performed, the date, and the mileage. If the odometer on the vehicle is less than the last recorded mileage, then you'll know they're commiting mileage fraud.
One says since dtc cleared and another says this driving cycle which one should be completed
Sounds like you have a higher end device than what was used in this video. I would refer to the “since dtc cleared” option.
My obd2 says ready and not ready, is that the same as complete and incomplete?
yes! You want the scanner to say ok, ready, or complete for all of the diagnostics!
@@CarRepairsMadeSimple thank you!
Question on Pontiac 2008g 6 with check engine light on so I gotta make just sure it no on then
You want to ensure that you do see a check engine light illuminating when you first turn the ignition to the car on. This way, you can ensure the light is working. It's important for this light to work so when a problem arrises, it will illuminate when the car is running to let you know something's wrong.
@@CarRepairsMadeSimple what are common problems driver says it drives fine with it on could I leave or needs to be reset
@@CarRepairsMadeSimple I’m buying the car Tommorow trying to check everything wrong with it
@@NateVega-jm3zf simply resetting the light isn’t going to fix the problem. The light will simply turn back on within a week most likely. Only reset the light after you’ve made an attempt to fix the problem. There are some things that can cause a check engine light but are barely noticeable, such as a loose gas cap. But nonetheless, it’s still important to fix any issue causing a check engine light to turn on to ensure no additional damage or problems arise and for your car to work as efficiently as possible
so, i bought one of these and ran it. everything looks good, no stored or pending codes. mil status is off and everything says ok or n/a. except for the evap system mon. which says inc. i haven’t been able to get a clear answer but what exactly does this mean???
Incomplete simply means the computers self analysis for the evap system hasn’t completed yet. This test can take anywhere from a few hours to a few days to complete until certain driving cycles have been met for the car to fully analyze itself. Incomplete in itself isn’t a bad thing, however, it is an indicator that the check engine light codes were very recently cleared either by using a tool like this or by disconnecting the battery.
@@CarRepairsMadeSimple thanks for replying! i turned off the car shortly after and waited a bit to test again. the second time, the evap system mon. had ok next to it and everything else looked good. idk why it changed in such a short time but i just wanted to make sure the previous owner did not clear anything off.
Thank you man

Hi, I bought the AD310 scanner for my Toyota Corolla 2005 and I would like to know if the device is compatible with my vehicle, because the communication between the computer and the AD310 is not established. I have two other vehicles and I had no problems with them. Could you please tell me if the AD310 is compatible with the Toyota Corolla 2005. Thank you.
For reasons that I do not know, the Ancel AD310 is not compatible with early model Corollas. Ancel does make a Toyota-specific scan tool, the TD700, but it's $95 on eBay. Maybe shop around if that's too expensive.
thank you brother
You’re welcome! Thanks for watching!
Please help, I purchased a used car and didn't check codes, I checked codes after buying and it has 3 codes but the dealership says the codes are just from memory storage and not active, he said it was a problem the car once had but is resolved, is that true? Or is the car likely going to give me the problem? I checked drive monitors and they are all ok and complete. I am taking a long drive this weekend to see if it triggers the car check engine light which is off. The car is used but does have a 3 month powertrain warranty which would include the codes I found when scanning. I'm wondering if I should just sell and not deal with it
It is possible for codes to not go away without clearing them manually. Why the dealership didn’t clear the codes after supposedly fixing them is questionable. Warranties also mean nothing to me. Car dealerships will do anything and everything to avoid having to fulfill a warranty. If the codes have not been legitimately fixed, they’ll come back usually within a few days to a week, and you can make your decision from there.
That's not always true
I/M readiness has "since dts cleared" and shows OK. However, it shows INC on "this drive cycle"? Will that data be something to look into as well?
Only the "since dts cleared" should matter. The "this drive cycle" resets every time you turn off the engine.
Thank you! Your video was very informative.
@@MrBinets you’re welcome! Thanks for watching!
Can you still use a scanner on your car even tho the engine light is not on?
Absolutely! That’s why we are using it here, to see if the check engine light was cleared or not.
1990 pick up truck? No way. OBD started in 1996
Marco Polo this is true, but point being that’s where you would hook up your computer.
Does it read transmission too?
It can read codes regarding the transmission too!
is the ancel ad410 okay to use? I couldn't find the one you listed.
sorry idk why that link wouldn't work anymore. Yes the Ancel AD410 would also work fine and can be used to look for Check Engine codes and I/M readiness systems. Otherwise, just type in Ancel AD310 on eBay and a bunch come up.
hello, is this obd scanner detects the real mileage in case of falsification?
Unfortunately there isn’t any any tool that can detect mileage rollback, only tools to change the mileage. This specific OBD-ii scanner shown in this video cannot do either. If you are suspicious of mileage fraud, you can get a car fax which will show the service history and mileage over time. If the current mileage is lower than what was previously recorded at an earlier date, you’ll know there was a mileage rollback.
✅great video
Thank you very much!!
what do you do if they reset all the codes before you scan?
Some cars don’t have history of resets :/
i would run away! plenty of cars out there, no need to chance it on a car with recently reset codes.
@@CarRepairsMadeSimple unfortunately we scanned it and it didn’t tell us it was inc so we bought it and then after about 100 miles the check engine light came on for cat converter but the timing just seems too suspicious. It’s a 99 Camry too so I should’ve known when there were no codes at all
@@mkaelacarat there can sometimes be a small timeframe until a CEL will be triggered, even after the readiness systems all say OK. If you got it from a used car dealership, you might be able to return it still if it's not too late. Or sometimes they'll even pay for any repairs needed within a certain timeframe after purchase. If you bought it privately, not a whole lot you can do other than fix the problem. Only so much we can do to avoid scammers.
Scammed this week on a Prius with blown head gasket. Pos craigslist dealer reset the check engine light. Text him later that day I swear the check engine light was off. Out 2500 for a engine swap.
Dang I hate hearing stories like this. Buying cars is so sketchy. My parents got screwed over buying a jeep, and it motivated me to make this video. I recommend doing this OBD-II check and getting a car fax to everybody when buying a car.
Does this work for airbag lights??
No,it is just a basic engine code reader,Please check more advance scanner that can scan abs/srs system
Will this scanner detect mileage tampering?
This particular unit cannot detect mileage tampering. I’m not sure if any unit can for that matter. But what you can do is get a CarFax or look at the vehicles service records if the owner keeps those and verify the mileage lines up with its history.
@@CarRepairsMadeSimple thanks for replying
You sounded like ray romano
If Fozzie Bear and Kermit impersonated each others voice
When I go to read codes before I drove vehicle there were 5. I cleared codes and drove the vehicle.check engine light came on but only 2 codes showed up. Do I discard the previous codes,thanks!
Mike Johnson It depends. Some codes may take longer than others to reappear, sometimes days and even weeks to show up again. Also, some codes won’t go away on their own even if the issue itself was fixed. So if you know the issue was fixed you could discard those codes. If there were codes to begin with but nothing was done to the vehicles, I would not discard them and consider the fact there’s a good chance they could come back again. But for now, I would just address the immediate codes that came back, and hopefully that could fix the potential issue of the other codes too, since a single problem could trigger multiple codes.
@@CarRepairsMadeSimple hey man thankyou for the reply,at first I used the mechanic on duty,s simple code reader it said 0088 .then used mine and pulled up all existing codes,PDF,d them then cleared codes ,drove it and came up with 2018-1 and 2016-1
After some research I'm going to test fuel return rail injector differential,test pressure control valve,measure pressure before and after filter,test cascade overflow valve, fuel solenoid pressure during starting and during cranking unplugged, check fuel pressure set point vs fuel pressure.unplug quantity control valve in the Cp3 and chk pressure default, pump pressure generation test using the drb3, check for fuel leak in one of injector lines, fuel line leak, fuel line between tank and low pressure pump.
I really don't know the meaning of most of these items but I can figure it out.
What you think man?
Mike Johnson it definitely sounds like there’s a lot going on and you’re on the right track. Idk much about your situation, but usually whenever I get a code, I enter it into autocodes.com and that gives a pretty good write up on what’s causing it and how to fix it. Then I’ll search the forums if I need additional information. I’d start with the 2 codes that came back for now, and only address the others if they come back after fixing your initial 2 codes and problems. I hope that helps some.
thsnks
You’re welcome! And thanks for watching!
I found codes that said inc. is it a scam
Truck drives fine
Might be becauze the battery was changed
@@cfsouthern It could be. A vehicle can appear to drive fine with a lot of codes, such as an evap leak code, but they're all bad and will lead to more problems down the road. Check the manufacturing date on the battery to confirm that a new battery was actually put in.
@@CarRepairsMadeSimple thanks for the info! I’ll check it out.
This video is bullshit i went to buy a car and 2 of the oxygen sensors said incomplete so i left after watching this video but when i came home i tried to use the tool in my car and it sais the same thing. incomplete and i never had check engine light in my car for over a year and i drove over 30k on the last year
I/M Readiness and Check engine lights are two different things. I/M Readiness is a series of self-monitoring systems that take multiple driving cycles in order to "monitor" itself and determine if anything is wrong. So if any of them still say incomplete, that simply means the car has not been driven enough since the last time the codes were cleared or since the battery was last disconnected. This can take anywhere from hours to weeks. A check engine light states something abnormal has been detected during the self-monitoring. So I think you're looking at it backward. If it says incomplete, there really shouldn't be a CEL yet. And that's the whole point of the video. People try to hide the CEL from buyers by erasing the code with a scanner or disconnecting the battery. So since you can still see an incomplete status, that means the CEL was cleared recently.
@@CarRepairsMadeSimple means should i stay away from that car or should i go with it?my car say the same thing incomplete but last time my check engine was on over a year ago and i drove over 30k miles already
Yassine yassine On your car, have you recently cleared the codes or taken it to a shop for repairs where the battery could have been disconnected? Or has there maybe been a dead or replaced battery? The 30k miles won’t matter if the system was reset somehow. But in regards to the car you’re looking to buy, since it has some incomplete system status’s, I recommend not purchasing that car.
@@CarRepairsMadeSimple yes i changed the battery 1 month ago also the car i was gone buy battery looks brand new
Yassine yassine yah that would probably explain why your oxygen sensor systems say incomplete since you had to disconnect your battery to replace it. It’s a bit longer than normal for them to still say incomplete, but not unheard of. And who knows, maybe the other guy coincidently replaced his battery too. The unfortunate part now is you don’t know if there were any codes. You could take it for a test drive and with your best judgement if you think it’s a good car, go for it. Otherwise, there are tons of other cars out there to buy.
