    Eric,
    You posted this about a week before the check engine light came on in the lady's car. We read the code, but seeing how it was an evap code, she took it to a shop that almost rhymes with "liar's home" for diagnosis. Tech said the sensor was reading incorrect voltage, and recommended replacement of the fuel pump assembly, which they had listed as 1.8 hours of labor. Total parts and labor cost, $700+. I replaced the pressure sensor on the ground in the driveway in less time than that, for 25 bucks.
    I enjoy your vids, your timing was perfect on this one.
    P.S. She took her car to that same shop for state inspection, failed for license plate bulbs being out. Said they looked at them, one bulb was burst, the other was burned out and the sockets were severely corroded. Wanted to charge for bulb replacment, socket replacement, and pigtail rewiring for $150. I pulled broken bulb out with pliers, cleaned the socket with some adhesive backed sandpaper on a flathead screwdriver, replaced bulb and a blown fuse.. cost a little over 5 bucks.
    Glad to see from your vids you don't run that kind of shop. You're the man!

      My kids car died one day he had it towed to the same brand shop they wanted to replace all kinds of stuff for $1700. Had it towed to a Scotty type guy who fixed it for $400. Can't recall if distributor or ignition module but it was some simple to replace part.

      There a better way to trouble shoot that problem . The purge solenoid is not suppose to be open all the time if it is you will get these issues. Its all vacuum related. Test light will tell if u got a good ground for the solenoid.

    As usual your diagnosis is efficient and accurate. Pinpointing problems until you're 100% certain is a display of experience and discipline. Actually I will admit that after watching these videos, I've become so much faster at diagnosing electrical stuff. So all your rambling is actually very helpful haha!

    My pressure sensor read about the same as this one did at the beginning (-1.6 give or take) with the key on engine off. I checked it because you mentioned that it should read 0 in that condition. I got to thinking about it, though, and realized that if there was negative pressure in the tank when the vehicle was shut off, and the tank is sealed, then there should still be that negative pressure. I opened the gas cap, put it back on, and sure enough, the pressure sensor read 0. I am, however, still watching the rest of the video to see if I can figure out the source of my problem. Thank you so much for your time and effort making these videos, I sincerely appreciate it.

    Just rewatched this because a 2006 Impala came in to my shop "Parking lot" with the same Evap Code Advance had pulled a PO496 too but when it got to me it wasn't there and it also had a Fuel Trim limit reached. I checked the Purge and Vent with the Purge and Seal car chugged but tank sensor never changed it was fixed at 12.66 mmhg and 0.22 volts. Dropped the tank unplugged the sensor went to zero plugged the new one and it went to 1.49 volts. Ran the purge and seal again and all was well. I also gotta plug Eric's video on Malibu runs like poo this Impala also had -18% on Long Term the Alcohol Content was at 22% reset the Fuel Composition and the Impala runs great. Eric You the man Thanks again!

    had the P0446 on my Pontiac Montana. Didn't have any of the tools to diagnose the problem but thanks to this video and the one you did on the pickup truck for the same code I took a chance and replace the sensor with a wells sensor and it cured my check engine light. I did have to drop the tank which wasn't an issue but was able just to reach up and switch the sensor all by feel. Thanks for the great DIYs

    I like your videos a lot and they are very helpful. As a hint that may help you in the future there is an access to the fuel pump under the back seat. If you pop the bottom part of the back seat out, which only requires a hard yank, the panel is close to the center of the seat pan and has a couple of screws holding it in. Also most cars have the same thing. May save you some good time on pump replacements.

    Experience of what the correct readings the sensor outputs should be, has been the signpost of where to begin.Correct procedure for verifying wiring integrity.Again the bi-directional scan tool has shortened the diagnostic down time.Liked the video and Wells Fargo delivers again.Need to feed the horse before I head for Washington.

    i know this is a 2015 vid but i really appreciate all the "fine details/thorough explanations" on the how, why, and where, etc..
    now, with my 2001 buick century 3.1l, i have a po446. i only have a simple code reader. i tested ground/power/solenoid operation on the purge solenoid w/multimeter and jumper wire, checked out ok, will test the vent solenoid next for same thing, i "guess" my gas cap is fine although i don't really hear that much of a fizz when i open it, and with this video, i have a strong feeling it will be the pressure sensor on tank (my luck). no ez access under back seat/trunk, will have to lower backside of tank on ground like the one comment you got. would be easier to get access to sensor from back side, which leads into my question as to why you lowered tank on front side as opposed to back side??? you had to stretch further from front side since the fuel pump was located more to rear side. fuel line in the way?? i would like to know ahead of time b4 i start. anyways, this has been the most helpful video about this issue than all the other vids i searched/viewed. broke shade tree mechanics have to do what we can with what we got. thanks, south main.

    • @geeess958
      @geeess958 5 років тому

      Hey, this is late but the back seats on your car do come out. You have to take the lower part out first, it is snapped in. Once you do that, the back in is held on by 4 or 5 18mm bolts and nuts due to a seat belt bracket, 2 10mm nuts and clips on the top just as the bottom portion of the seat was clipped in. These top clips make it hard to pull this backside of the seat off but you have to kind of put force on it. Once you do that, you can pull back the carpeted area covering the access panel. Ive done this on 1999-2005 Century due to fuel pump issues. As for your mystery p0446, did the sensor correct it?

I have a 2008 Impala 3.9 and even when the check engine light is not displayed error code P0446 it is difficult to put fuel into the tank, gas pump nozzle clicks a lot on fill-up. I like the Wells replacement part you used. I noticed right away that the seal had more levels of sealing (layers) than the original part, a better design. I will subscribe. Thanks.

    Hi Eric! So what a coincidence. I just had this same code on a 2008 Malibu ! Customer brought the car in complaining of long crank and the smell of fuel. Well i pull it in and could definitely smell the fuel. Didnt really get the long crank but the car was warm. So i hook up the solus pro that our shop has provided for the two of us and this code comes up as well as p0430 and intake cam position sensor bank 2 cant remember the p0 number . So my first step was to raise the car and see if i could determine why the strong smell of fuel. Get the car up in the air and find fuel wetness on the right rear of the tank. Pretty much says i gotta drop the tank. Oh one thing that the code description was a restriction in the evap system. So Im thinking broken evap line on the top of the fuel tank and i was also thinking tank pressure sensor ( not the first time ive encountered this). Anyway get tank down and find a puddle of fuel all around the fuel pump but couldn't see where it was coming from thought maybe bad oring seal? Well my partner comes over and takes a look and finds the fuel pump outlet line has a very small crack( he has much better sight than i do) lol. So fuel pump would be the first fix which i completed and the customer ok'd the cam sensor as well. When i get all done i leave the exhaust off the car just in case i need to go back . I clear the codes and run the car for quite a while and keeping an eye on the evap data. Ran it for quite some time and codes never came back . One note though i do believe the cat code is going to return the 02 sensor #2 was switching much faster than bank 1. The customer did not ok the catalytic converter repair. Anyway was really surprised when i seen you put up the same code i just dealt with Thursday . I watch your channel every night and learn so much from it. especially how to torque to factory spec lolol. Just want to say thank you and i appreciate you putting the time in to help us others. God bless you and your wonderful family and may your dayz be filled with joy. Again thank you😊👍

    @jackhayes7918 4 роки тому +1

    Eric; For verifying the operation and accuracy of a gas tank pressure transmitter have you considered making up a filler cap with a pressure connection? This could then be connected to a low range pressure gauge or a manometer which would verify the operation and or accuracy of the pressure transmitter, as well using this same connection you could increase or decrease the tank pressure for further testing.

      only saving grace is since the car 1999, Mass no longer does the emission check on it during its annual safety inspection but I am getting very tired of staring that CEL all the time. The cost of the EVAP canister for that car exceed the value of the car!

      I was gonna say , most of the time on the Yota's it is one of the VSV valves but in some cases you have to buy the whole canister.

    Could you get a No Start/Stall on start up without getting any Codes or Check engine lights? My Chevy from time to time when Cold, Warm or Hot will not start; turn the key and starter rolls the motor over and over but no codes, no start. I just keep trying it and sometimes blip the throttle and she will come back to life. This even cause the Immobilizer Light to come on once but it has never done that again since. Dealership changed out the Cam Shaft & Crank Sensors and put a new Starter in. Said that the start housing was coming off the core. I get into the car and randomly it still will do this fail to start. It happens more when I park the car but leave the key in the Accessory On position to keep the radio on for a passenger when I run into a store. I have a simple scanner and even the real time data looks normal. Now watching all of your Evap vids I am going to start to look at those read outs. Thanks!

      Darren G. - Get scanner danner's book, it has very good teaching methods plus the book can be used as a reference guide to always have on hand. Understanding theory is much better than having to rely on engineer's flow charts. You won't be disappointed.

    Love your videos. I have an 07 GMC Yukon 5.3L. It throws a P0446 and occasionally a P0451. I have personally replaced the vent solenoid, purge solenoid, and hose leading to the purge solenoid. The check engine light keeps coming back with a P0446 code every week to week and a half. Garage can't find any leaks with the smoke machine. All parts are OE. I'm lost on this one and would love your opinion. Thanks again for all your videos.

    • @IsshmanGarcia

      Check power and ground. If that passes, check for corroded wires. Start at the connector and give wires a stern tug. If there is corrosion in the line it will no doubt break with ease. If yhe wire isnt corroded, it will not snap with a tug.

  • @digitalrailroader

    this diagnosis may explain the issue with my 2010 Aveo; because its throwing the same two codes. (I plugged in my VCXNano with my Tech2Win software, and saw that my FTP readings are even more wigged out than this Impala at -8.64 inches of water, at 3.4V!) unlike this Impala, GM Korea was gracious enough to provide me an access panel to my fuel pump underneath the rear seat.

    Great info Eric. Thought your video on EVAP was my life saver, but something else is going on. 2007 Impala throwing P0172(Rich bank 1),but the only monitors not finishing are EVAP. Short term -3.1%------Long term -21.1%. EVAP purge 0%...Alcohol fuel 50.2%. All o2's check out.. Do you make house calls? LOL What gives?

    i wish we could have seen the dtc passed since clear list. i think the only test that runs on the drive test is the P0442, so it would have showed us that your P0446 ran and passed along with the pressure sensor codeP0452. i just hope we do not have an intermittent vent solenoid.

    I've got a 3.9 06 impala and it was a police interceptor or whatever. Mine starts to misfire while driving? Than stops after like maybe a mile. The same day I was sitting at the store and it started to sound like it was going to stall so I shut it off for a few and went and got gas because I was low but not empty. I did change my fuel pump a few months ago also.. will the computer still be able to read codes with it being a cop car? "Was"

    I know this is an old video but and though I don't understand all the voltage stuff I can clearly understand the physical aspect of it... I have a 2007 impala which I have the engine light on, I had it put on a hand held at AutoZone which they hooked it up to their computer and it list PO455 fuel tank pressure sensor... in another box it lists PO 442, and their answer by experts say it is mostly the FTPS … If you would answer this question, I am sure you are busy and I realize you cant answer every Yahoo on UA-cam.. lol , but I would assume the location of the sensor is the same as on this 2006 impala.. This was the only impala video I could find... Assuming it`s the same, once I have it down are there any other parts that could be if it`s worth it to replace while I am at it... I really would appreciate if you could answer...I am 66 years old, I really have to fix it myself if I can for financial reasons even though it looked easy as you did it with the host and stand I will be on the ground.. I don't know , it runs real smooth, can that part cause it to not run at some point and could you give a ball part figure on what a garage would charge to put one in.... Again I know I have ask a lot and if you could answer, and if not that's good I respect that... It was a very good video and I have a very good idea of how to do it … Thanks …..

    I had a evap solenoid go bad now if i were working on one Id buy or rent a vacuum pump to check the solenoid u can troubleshoot the solenoid to see if its the problem or its a leak in line between solenoid and intake the hoses tend to leak causing this code too . If the solenoid is leaking this issue can happen too thats what the vacuum pumpp will test.
