Please help me with my 07 caliber. I have a code for the p0116 and p0335 crankshaft sensor; the problem is that the car has a long crank on a cold day so this is what I have to do to get it running pretty much all day
First start it with long crank in a cold day(60'f or under), let it start and idle for 5 minutes at least If is really cold from (1 to 20'f) maybe 10 minutes so next cycle the key on pressing and releasing rapidly the accelerator key off , starts right up normal everytime for a whole day
But the weird thing is that when it is like 80 or 85,90'f outside really hot day, the car will start right up no long crank at all please help
Quick pre'fuel injection story. Back in the early 80's I was making a delivery to the D/FW airport and driving a 1972 Datsun w/over 300,000 miles on it; original engine and had never been opened up befire. Our trucks always had oil changes every 3500 miles so they lasted forever. Anyway, Im on one of the side roads at the airport and the engine dies. I crank it over and it sounds like it wants to run but doesnt. I pop the hood, open the air filter housing, crank it over and the engine runs. I think great, put the air filter housing on, as soon as I clamp the air filter housing on, the engine dies. We tow it back to the shop. Take the cam cover off and the camshaft was snapped in half. I was impressed w/that little Datsun. When the air filter housing was off the 2 cylinders attached to the oil pump and timing chain drive were still firing. Put another cam in it and the truck never skipped a beat; ran till we sold it years later. Engines are always fun. Throw in fuel injection and an ECM and the fun just never stops. Really enjoy your vids. You and a few others are great teachers ;)
Hey Kevin, awesome story! Wonder why it snapped in the first place...i guess at that kind of mileage something was bound to happen. Thanks for watching!

The 1972 Datsun was suppose to be our light duty delivery truck for small packages but we regulary used it for 1000 lbs loads and on occasion oil well rig blocks @ 3100lbs; going to/from the heat treatment facilities. We bought it new in 1972 had overload springs in the rear and 8 ply tires on all 4 corners. The little truck def paid for itself multiple times over.
I don't even know what to say other than "brilliant". Extremely educational.
Thanks a ton Lyndlle!

I'm not a mechanic so I don't know why I watched this from start to finish, I guess I'm just curious what makes things tick. What amazes me is the wealth of knowledge you have for a comparatively young age. Seems like it would take an entire lifetime to learn such complicated systems. You're a great teacher
Hey Thom, it must have been my warm personality ;) haha! Thanks for watching and for the amazing compliment. I really appreciate it :)

Another great presentation!!
Lots of people in the industry forget their humble beginnings and perhaps that's why they are annoyed by your method in this video. However the majority of viewers are thankful that you took the time to educate us from the ground up!
Continue making tutorial videos for the general public, those "experts" really shouldn't be here since they know so much
Hey, thanks man! Appreciate it! This video had a little bit of everything. Stuff for beginners and stuff for seasoned diagnosticians. I prefer my videos contain a little bit of everything for everyone :)

Your going to make life a whole lot easier for a whole lot of people who struggle with this sort of thing. Keep up the good work !!!!
Hey Robert, that's the goal! Thanks for watching!
Mike Becker, Senior Technical Instructor
Great class Mike! That diagnosis was done in a few seconds of cranking and only equipment needed was my ears :D Now to find the cause would take a little longer but I wouldn't even charge a diagnostic fee unless they wanted me to find the root cause. Nice diag...Jumped time, bent valves, spit rockers and your right customer's repair choice .
Hey Bob, thanks! Yep, that's what experience will do for you! I was under 30 min on initial diag to confirm my suspicion of mechanical failure. Odd cranking cadence led me to a relative compression test, funky relative compression results led me directly in-cylinder. The right equipment here saved a lot of potential teardown to confirm.
Mike Becker, Senior Technical Instructor
Pretty intense presentation with all avenues covered. Can be used as a reference video for any tech that has come to a cul de sac in his or her diagnosis, The range of tools used are awesome and every tech is covered from the novice up to the professional. Videos are too long when there is no content. This video screams content and is a credit to Mike and his team. Well done and looking forward to more exciting car problems.
Hey Tom, thanks for watching! I hope it is a reference to everyone who's diagnosing this issue! Glad you enjoyed the class :)

Great work on this video. Timely info for me. I just sent a contact us email to you guys on a hot start condition. I just got most of my gear together for my first laptop scope (Pico 2000 series the lowest mode). I just got my first waveform today. I will run through these test to try to fix my 04 Venture 3.4 that is just about to reach 200k. Thanks to all of you at Wells for putting together these wonderfully information packed segments.

From Nick Ayivor from London England UK 🇬🇧
Superb presentation, Mike! The way you explain and handle tools and cameras for two hours straight... is nothing short of magic.
One subtle mishap with Picoscope cursors happened and went unnoticed at 1:01:06 : you grabbed a cursor, but it didn't "catch" and dropped into 180mA zone. So you grabbed another one. Thus your cursors window made it seem like you have 176mA current, when it should have been more like 20mA. Which, of course, only bolsters your point of that circuit being a low current one.
The thing is this issue happens to me more often than I want to, I wish it was a little bit harder to lose a cursor while it is being dragged...
Thanks Dmitriy! Really appreciate the kind words. I did notice that afterward upon watching the video....Current was WAY lower than what I said. Anyone who watches and is familiar with PICO (like you) will notice that and hopefully see what it really way. Thanks for finding it!

Hi Mike. Man I'm sooo disappointed I missed it LIVE. You did and awesome job sir. As soon as you cranked it for the first time I wanted to see relative compression but was even more curious as to how it would look if all cylinders were low. I'm familiar with one low cylinder already. Now I know. Awesome. I really would have enjoyed being in the chat room also. Great people today. Fantastic job as always Mike. Looking forward to next months class.

@@GoTechTraining Yes, all is good here in Ontario. You'll be happy to know I've added a DSO NANO scope to my aresnal of hantec and pico. Its identical to the U scope. Just lacking knowledge now. Like I didnt know about not loading the signal wire on a 3 wire coil. I do now. I'll have to try Keith's idea about a penny on the COP alligator clipped to the scope leads. Sounds interesting although I do have the OTC COP probe.
Thanks for taking the time to do these presentations for everyone. You're very much appreciated and well respected. Thanks again Mike.

Sir, you are the only one I know who can help me out with this car problem. The car is a range rover 1998 p38 4.6HSE and v8. Many people were invited to start the car even from a far State but the couldn't. The challenge is a crank no start, no spark,no injector pulse but good communication with a scan tool. I have added fuel to the intake manifold and crank the engine no change at all. It is not starting. In addition, I checked for spark, but there is no spark as well.
Hence, I have just checked for injector pulse but there's no injector pulse either. There is also no ignition current to the injector circuit with key ON and engine off.
All the fuses and relays are good. I also checked the injector circuit for continuity if the wire is shorted but it was ok. Scan tool communicated and showed only p1843 and p1842 code. There was no RPM during cranking. What I noticed today when I compared the ignition, earth and DC with the same car that was starting and driving to the car that was not starting, what I saw made me to flabbergasted. Where the was ignition for example in the working car there was DC in the car that was not starting. Also a particular relay circuit for example RL-2 one of the pin of the connector when my test light was on battery ground and relay removed, the pump buzzed and testlight dim but when I tried that same location with test light and same pin the test light was dim and ABS relay was actuated no buzz from pump. It is like that in many places in the fuse box and PCM circuit. Please what's the cause of the problem and what do I need to do to fix the problem?
Very nice video!!!

@@GoTechTraining I have learned so much from your vids not just diag but understanding how things actually function. seems like NGK are putting you under pressure to do a quick skip this skip that. didnt have that from wells tech
Hey Darren, that's not really the case...it's just a matter of trying to keep the video at a decent length. Performing and testing EVERYTHING for a crank/ no start diag could take an 8 hour class for sure. The goal here was to show some basic tests and some high end tests that lead you with the most answers in the shortest amount of time. To date, this is our longest training class.

Hey Salvador, thanks for watching :)
Mike Becker, Senior Instructor
Very intriguing video,
But, wondering about your use of a scope attached around the fuse testing the fuel pump...
Is really helpful to be able to test the fuel pump when it's in or on top of the fuel tank and is not immediately accessible...
- Is a scope necessary, or is anything possible using an volt/ohm/ammeter?
- Related to the above question about using a volt/ohm/ammeter, if possible and measuring amps, then I wonder if a clamp-on meter can be used.
- Are you testing only for bad/good fuel pump, or some condition? Or, maybe even if for some condition, maybe it doesn't matter if it's some condition serious enough to warrant replacing?
Thanks in advance.
Great video! Do you have any experience with changing the camshaft sensors on a Hyundai 2007 Santa Fe 2.7L? I have a crank / no start issue w/ zero rpm indication. I cannot remove the Bank 1 camshaft sensor (seems the engineers at Hyundai designed the water lines that go to the cooling assembly to encroach on ).
Really good stuff

Hey Mike, good video! I have a 2.4 engine swap, dodge 2011 block ,08 head , in a 2015 dodge journey got it installed an it won't start ,throwing codes for crank an cam sensors malfunction, replaced all 3 sensors an still no change, took a scope an looked over reluctor wheel, looked ok, checked all relays an fuses, timeing to my knowledge is on ,looked over it several times unless there's something I missed, I'm lost on where else to look ,wiring to sensors looks fine unless there's something hidden, I put scan tool on Dtc an its telling me pcm checked out ok. I could use some idea on another place to look, Thank you
it's got a bicycle chain for a t chain belts last longer it's a cheater way to add vvt this is common on this engine great class like always
Thanks for watching Juan!
Mike Becker, Senior Technical Instructor
You should use your pico scope and do a relative compression test first. It takes a minute to do. Every driveability concern should start with a relative compression test imo. Another quick thing I will do is try to get it to fire on some brake clean or starting fluid. If you suspect broken timing chain/belt watch for valve action thru the oil fill cap ( not always possible). These 3 tests will take me less than 5 minutes.
Aaron, Relative compression is an AMAZING first step. The other 2 can be valid, but are dependent upon the vehicle. Either way. Quick tests that provide a ton of info are critical!
Mike Becker, Senior Technical Instructor
Perfect excellent performance
Thanks Ivan!!

Hey Jeremy, thanks!!! I do not. I create training events/material full time here at NGK.

Good job scanner danner
If a late-model car won't start due to spark, it's usually a crank or cam sensor. If a car won't start due to fuel, it's usually a fuel pump relay or pump. Once in a while it's the wiring. Usually not the ECM or timing or compression.
Hey George, i'd be careful with assumptions like that. It could lead you very quickly down the wrong path. When I diagnose no starts I assume nothing until it's been tested and proven. Your mind can play tricks on you otherwise.
~Mike
I've never seen that before. The roller mia crazy
I know, right!? Something had to give. I guess that was the weak spot? I'm curious to see what kind of shape the valves/pistons are in. If I get the ok for a motor in here I'm going to tear this one apart just to satisfy my curiosity!

I was called to another garage to fix a 2005 300c chrysler. The problems they noticed with the car was Hard or no start, red lightning bolt flashing, no throttle response, headlight stays on, battery and ESP light remaining ON during, most times immediate stalling after starting however, if it doesn't stall there's a rough idle throughout idling as a result a old PCM was replaced with a new one however problem still persisted.
I scanned for DTC codes and saw a P0340, P2167, P2166, P2115, P2116, p0603 and more module codes like C2202, U0168, U1414, B1A25, etc.
Please, how can I fix these problems?
Can you also 🙏 provide me with the wiring diagram to CMP, CKP, APP factory values and how to test them? What should I be looking for in fixing the blinking red lightning bolt limp mode light, how can I reset the throttle without a scanner?
🙏 How do I fix that?

Hello, Mike. What voltage is expected to see in a pcm controlled ground before and after the pcm provides the ground? Some type of bias voltage before and 12 v (Voltmeter on battery pos?)
Hey Little7, it really depends on the circuit. Almost ALL PCM circuits use low reference, a few hundred milivolts at most, for the ground. The high voltage side of the square wave can really be anything. Some are 5, some , or 9, or 12. Depends on the car and the circuit.
Mike Becker, Senior Technical Instructor
great vid
Thanks Mason!
Mike Becker, Senior Technical Instructor
The engine oil appears to be super thin. Makes me wonder if the previous oil change included the improper viscosity of oil, which lowered the tensioner's ability to keep proper pressure on the chain. I don't foresee Honda specifying 0W-20 oil in an engine this old, if that's what was used.
Hey Joseph, that oil looking thin may be the effect of all of the cranking I had been doing. Engines flooded and diluted the oil. It smells like fuel.
Mike Becker, Senior Technical Instructor
God Bless You 😇🙏💖
what I would like to hear explained is how does the transducer in one cylinder indicate a problem in all the cylinders.?
I think the relative compression test was the actual test which exposed the system-wide problem, then the transducer took a sample of one cylinder. So without a visual inspection, one could conclude the issue was definitely across the 4 cylinders.
Good Evening Mike Becker Go Tech
Timing chain should be replace 80,000 ,120,000miles on vehicles 6years

2011 toyota highlander 2.7 l no start and found water at the spark plugs.
Actually injection occurs while the cylinder is coming up to evacuate the exhaust gases, the pulverised fuel is kept in the port until intake occurs.
Depends on the engine and the injection method. Also depends on what VVT is doing to the intake valve. Fuel injection is a hard thing to rely on.
Mike Becker, Senior Technical Instructor
@@GoTechTraining Honestly, a fuel pressure of aprox. 3.5-4.5bar (that's roughly the pressure in a PFI engine) is not enough if the injectors open when the intake valve opens. The valves would be shut before all the fuel enters the cylinder, so the fuel must be delivered in the port before intake valve opening.
BTW, i've learned alot from your videos, especially fuel trims and for that i say: Thank You and a big appreciation!
Awesome video mike . Did the customer fix the car? what did you have to do to fix it?
The customer is still undecided at this point. Cars still on the hoist where I left it yesterday.
Mike Becker, Senior Technical Instructor
Mike a quick question.I have a 1.8 vvt engine .one cam sensor and crank sensor and two solenoids for the vvt.I have a 2 channel pico and would like to get a known good cam and crank corralation.Would i be better off disconnecting the vvt solenoids to get a better waveform or should i leave them connected?Also if done with them disconnected would it harm anything.Would like to see a vid on testing vvt with basic tools and advanced tools.Thanks again for the great explanations.
Great question...so when taking cam/crank correlation style captures it's always a good idea to verify the VVT does not operate at your testing range. Cranking/idle/whatever. The easiest way to do that is by unplugging them. Most cam phasers are pin locked to the cam and stay locked until oil pressure is applied, so no, chances are you won't damage anything. Some engines do change VVT at cranking or idle though so it may affect the way it starts/runs. I really want to do a video on VVT...just waiting on a car with a failure :)
Mike Becker, Senior Technical Instructor
@@GoTechTraining Thanks Mike for the quick response.

Tiguan 2014 Right hand side Back brake light dead, flicker light working. Tested not the light unit or globe. What is the control box fuse for the right break light? 25? left hand side break light working no problem? Please advise?
Hey Francois, so I've looked at the diagram. It looks like a black and green wire powers up the RR brake light bulb. That is being fed from a control module and not a direct fuse. Do you have power on that wire?
~Mike
@@GoTechTraining Tx , no power. Auto Electrician told me it might be the control box. :(. He suggested to reset control box, if this is not working control box need to be replaced (expensive) a cheaper option to feed power from alternative break light at the back.

first look sensor might be the best way to tackle these problems my humble opinion

Mike Becker, Senior Technical Instructor
@@GoTechTraining exhaust pulse engines are pumps
(I, don't have any crank and no start. I, notice that I've got 3 fault codes that popped up on the cluster. I, asume that 1 out of the 3 codes is keeping it from cranking and starting)
Doubt it. Point is better. To do a pressure test in most cases to see what direction your are going. And then see if a scope is needed to be pulled out. I have also up sold pumps regulators and even some Injectors due to leaking. Wasn't the cause of their problem but it answered questions they had but didn't tell use about.
Don't you just love it when you don't get the full story!!!!
Mike Becker, Senior Technical Instructor
So by clamping an amp clamp around the fuses that feed power to injectors and coils you can tell which ones are firing and which one's arent?
True, you can pick out oddball ones. Now you would need a trigger point to understand which one is MIA but it's a fantastic test.
Mike Becker, Senior Technical Instructor
@@GoTechTraining would you then be able to look at just one coil by amp clamping around the power wire of a single coil?
Not usually. Most of the time the coils all use a shared power circuit. You could look at the individual ground feed current if the drivers in the PCM. If it's a smart coil you won't see much for current on the signal circuit from PCM to coil.
Mike Becker, Senior Technical Instructor
All lights come on when key is in first position. If no codes show check fuel pressure
(I, took a jumper wire to were the starter relay is at and sprayed 3 shots of starting fluid inside the air box then the car started up. I, need to find out what those 3 codes are that popped up)
it sounds like its probably something related to the fuel system then eh
about fuel : isn't old bad fuel also be a factor of a no start?
I have a 2003 f150 5.4 engine can I manually inject fuel too straight to try to start the my truck
Hey Raul, if you try it, you want to be very careful. You don't want to flood it out or anything. A little starting fluid goes a long way.

Haha, right!? Still cranks over though...looks like a future issue for sure.
Mike Becker, Senior Technical Instructor
@@GoTechTraining
I live in Canada, and i know you're in northern US, so dealing with the harsher winters and salt and sand on the roads, i always stay up on things like that. Battery cables and ground points, i always make sure they are clean. Just one more thing to rule out down the road.
Im only 30mins into this vid right now, and id already be checking for injector pulse! Had a similiar issue couple years back, and checked everything but the inj pulse, and sure enough, injectors were not firing off...so a pcm swap got me up and running again!
So true! I wish everyone thought like you! I live in Wisconsin, so very similar weather. The point of this class was to show all the different testing. It's up to the individual which path to go down first...fuel, spark, air, or compression.

It normally take longer to do a fuel pump current test then it does a pressure test.
Does it? I'd be willing to bet that I can scope the pump on here quicker than you can unbolt the line holdown, get the brittle plastic clip disconnected(without breaking it) and getting a gauge on it. On a car that's easy, sure. One with a schraeder valve, sure. Something you have to hook in line with though...I don't know. Bet my tests faster. Let's do it Phillip! Make your way to Fond Du Lac, WI! We can time it :) Either way though, they are both great super valid tests!!!!
Mike Becker, Senior Technical Instructor
@@GoTechTraining see my second post. But don't get me wrong a current test is a incredibly value able tool. And would probably be the next tool I pulled out. But I normally don't have my scope stuff laying out all ready to hook up. Plus u have to get the diagram. Then get to the fuse or relay. Possibly the wires on some models.
All valid points! Depends on ease of access of stuff for sure. Fuel pressure on many vehicles is a 2 minute test. I'm all for it. Just another box we can check of the ever-growing list :)

how can i sign up
How to change a camshaft sensor 2011 Toyota camera
How to diagnose a crank no start no communication with one 2 ? On 07 Toyota Camry
Start by reestablishing communication. Check fuses and simple things first. Many times the cig lighter fuse is tied into the power to the DLC. You blow that fuse because of a phone charger or something and you loose communication.

Yes please 🥺
Thanks for watching Barry!

A faulty ECU may not supply spark and injector pulse signals. Replace the ECU. Been through this twice.
Sounds a bit like an expensive guess on there Wayne. Spark and fuel can be disabled or not pulse for a lot of reasons.

I used starting fluid to see if it will start and no start. Do I still need to check fuel pressure?
Hey John, I don't trust that starting fluid will do the trick everytime. Maybe you could move the fuel test down your list of diag but I wouldn't go saying fuel is ok yet.

Low oil pressure may also cause timing chain issues.
Sure it could! Thanks for watching Victor.

Hey, Mike. Will a car ever run without a crank sensor?
Hi, what about the WELLS VE channel?
Hey Angel, we have stopped adding videos to WellsVE at this time.

How about Dodge Dakota 3.9 1992 to fixing all kinds of engine problems that I have been dealing with please help me
Ignition lights not coming on
I'm have problem with the 2007 pathfinder nocrank
I have a problem with Nissan after '98 IN GENERAL. I won't buy one- unless it's just about free.
Would you take that motor out the bottom? You should show how that's done.
I believe this is a top pull engine. If it's like the 1.7L or 2.4L. I've pulled each of those out the top with the trans bolted to it. Pretty easy job really. I just finished R&R a 2.4L vtec in an 07 Accord. A little over 2 hours from start to engine/trans on the floor. And that's in my home garage lol!
Mike Becker, Senior Technical Instructor
For a manual gearbox, drop it from the bottom or pull the gearbox and engine together, there is usually not enough space between the front of the engine and the chassis rail to get clearance for the flywheel/clutch and gearbox on transverse engines. With an auto you can generally get clearance to remove the engine alone through the top.
Usually I pull them together. These motors/trans come out pretty easy.
Mike Becker, Senior Technical Instructor
@@GoTechTraining yup! just depends on the situation, I generally try to keep the trans and axles in place so the car can be rolled away from the hoist or pushed outside
Sure, that makes sense! Working at home, I don't have to worry about pushing stuff out. 1 project at a time :)

lift back seat up to get to fuel pump...how hard is that?
I wonder if it is wise to use an impact on a spark plug?
When you see the end of the video you can understand why he did use the impact lol
Cranking no RPM. WHAT WILL BE THE PROBLEM?
Did you find the problem?
Crankshaft sensor
Timing
what would you do without that computer?
check plugs have sparks.....then check fuelfilter and pump
A bit hard to do on a petrol engine. Maybe you could make a video of you doing this and post it so we can all see how it's done.
Hola mike clases en español porfa
Orlando, our Spanish trainers no longer with us. Sorry :(
