    Excellent presentation, Matt. THANK YOU. Decades ago on my very first (part time) job as a teenager my boss used to tell me, “Son, what you don’t do with your brain you have to do with your back.” On automotive, what you don’t do with your brain you have to do with a wrench. Thanks again for showing the way on using the brain on auto diag and repair.

      Thanks for sharing! That is great, great advice.
      Actually most mechanics I have known have had bad backs too. turning a wrench is often bad on your back so the less you do it and the more you can do on a computer or using a dry erase board, the longer the career you will have!
      I will have to use your old boss’s advice in my next video. I love that.

    The background story, the case study and mapping procedure, this is keys to success. I appreciate this kind of thought, this kind of logical and technical approach to a scenario. Im currently dealing with a crank no start issue which had a camshaft sensor signal error on the scan tool and we've already detected shoddy wiring. We havent gone through the entire harness but at the connector itself was some damaged wiring and bad soldering and connections made. Replaced the sensor but still no start. So ill test the sensor wiring once the mechanic arrives tomorrow or before he gets here and we'll see how this gets us. Thanks,. Happy to have invested 31 minutes of my life in this informative video. Much appreciated from Cape Town, South Africa.

    This channel is absolutely awesome I love how you break down the diagnostics.Ive been having a similar issue with my wife's 2008 Chevy suburban the car is hard to crank than the traction control deactivates no signal to the tack at all car will drive with a p 305 code but hard shifts into second gear pings and runs like crap. I reset the engine code and the car runs solid for a few days and all of a sudden just decides it wants to act up.I look at the live data on the scanner and it doesn't even have a hiccup while driving. The other issues is a slow crank like it's got a dragging starter or bad ground things giving me one hell of a headache but after watching this I know I need to look at these wires and see what the hecks going on.

    Scotty is good for entertainment and basic information. Matt is a scientist/mechanic who's great for determining the truth. I can actually hear the wiring/short in my 08' Subaru, AFTER the "reputable" local shop replaced the ecu , which didn't solve the problem, and, after I got a "BlueDriver" obd2 scan tool which immediately caught a crankshaft position sensor code. "Tickling" my Subaru ( visual inspection and listening ) has me moving scientifically closer to the Truth.

    I've been having an issue with my 2015 fiat 500. Initially i was getting P0336 and i went to the fiat dealership to get it replaced. After getting my car back it barely started. Went straight to autozone and was getting P0336 still along with another code stating that the sensor needed a relearn. Brought it back to the dealership for them to relearn the sensor. Went home and realized that the 3 page report they gave me only showed them updating the ECU to a new version, nothing was mentioned in the report of an actual relearn. Getting the same codes. Not sure what to do at this point.

    • @SchrodingersBox
      @SchrodingersBox  Před 2 měsíci

      Start with the extreme basics: What are your signal voltages showing? What’s your reference voltage?
      By the way a relearn has nothing to do with timing or anything. A relearn is to allow the sensor to calibrate for cylinder misfire identification. Not doing a relearn has no effect on performance- it will just affect accuracy of the misfire detection.

    You could also test each connector pin with the car shut off using an ohm meter, by back probing a pin with one lead and probing the other end with the other lead and then wiggling it. If it deviates even the smallest amount from zero, you have a bad connection. Doing it this way is also safer as long as you probe each pin to ground first to make sure there isn't any live power. Unlikely that there is, but better to be safe than sorry.

      yeah it’s funny you say that- I was going to use the pierce probes but the CKPS wiring goes right into another harness that is still behind the starter so you still can’t access even with probes without removing the starter. no way around it, starter has to come out.

I double checked the wiring with a multimeter from the connector up to the top of the harness and both the wires were good so I knew that it wasn’t the connector or the wiring, so I bought a AC Delco knock sensor, and put that in and everything is good, no more check engine light!

    Fantastic! Thank you for sharing the all-important thinking skills for fixing weird little schtuff like this. Subbed! I so appreciate your though process and coming up with a diagnosis hypothesis and plan, based on analyzing symptoms Having a theory that we are looking for a sketchy wiring/connection issue FIRST is miles ahead of simply replacing parts. Recently had a Ford Focus 2002 with no blower. Found bad fuse. Replaced fuse. Nothing. At that point, removing blower motor and testing with 12V power supply, motor appeared dead. Took a flyer and bought a new motor--tested good on same 12V power supply. Yay! Not so fast--installed motor--nothing. Except on Max blow setting--worked on that. Aha! That is classic bad resistor symptom. Replaced heater resistor--success! All worked! Your approach of seeking "Why" symptoms happened... Well, blown fuse apparently a result of motor seizing up that final time, and possibly blew out the resistor too, or maybe resistor already bad. Anyway, love your process of analyzing the symptoms and seeking to understand most likely causes, and having a plan before simply throwing parts at the problem. Thank GOD I didn't have to depend on my auto mechanic skills to feed my family; now THAT would have led to a LOT of trips to the Food Bank...

    I have a question for you.
    There seems tto be alot of issues with BCM system,with water leaking into Hummers and it creating a mess of electrical issues.
    Not only that these GM cars and truck from the early 2000's have electric issues.
    I have ad H3 Hummer, that has haall kind of electrical issues because of water coming in from the leaky sunroof,and draining down the a pillar and getting to the BCM.
    Now the sunroof has been siliconed and so no water is coming in.
    Now the question,I replaced the BCM with a preprogrammed unit,and went through the 30 min passlock system relearn and the car wouldn't start.
    Did it several times and still nothing.
    Notice that the crank sensor code along wiht air pump code is on,so the car isnt gonna start with the key.
    But if I tried using just the remote start and did the 10 min reset for 30 minutes and the car starts up,but will not start with key.
    In the beginning there were 2 codes on the crank sensor and the air pump,both parts were replaced and the codes never shut off,
    I think the car is not starting from the key because the crank sensor code is still on,check the fuses and wires for breakage,every problem sight of a ground missing,nothing!

    Hey Matt, I have a diagnostic question. I'm working on a vehicle nearly identical to the one in this video. It is a cranking no start scenario with no pule signal to the injectors and no spark. I have a positive reference at the cps plug, and the fuel pump kicks on when I do the crank bypass shown in this video. What I don't have at the plug is a constant ground. Would you lean towards crankshaft position sensor with this information, or chase the lack of ground?

    I have a 2004 dakota 3.7 engine with the same problem, the engine was removed for oil pan replacement exhaust leaks on the heads,the engine ran fine before removed after the engine was installed back in it make about 10 revolution before it fire the po355 came on it run fine at a idle but it won't pass over 2200 hundred rpm replacement or cps was done and the problem still there.

    My sister had a 03 Nissan Pathfinder with p0335 that had the exact symptoms he described before swapping the crankshaft position sensor. I could never get confirmation it was the sensor and it only threw the code one out of maybe every 10 times it refused to start so I suspected it was just a referenced code.
    The only thing I could find wrong for sure is the fuel pump was out of spec, only giving about half of it's rated fuel pressure.
    Not fully understanding the mechanisms but trusting in the data I had, I decided to replace the fuel pump. Completely resolved the issue.
    I suspect what was happening was the vehicle had no way of knowing it had died due to being starved of fuel, so it threw a crankshaft position sensor when it saw the crank was no longer spinning. What the PCM didn't know is that was legitimate, the crankshaft _really wasn't_ turning anymore due to a sudden loss of fuel.
    I further suspect the fuel injectors have a very specific pressure that they will no longer open at all (thinking like a "burst pressure"), causing the low fuel pressure issue to go from "running fine" to "not running at all".
    Moral of the story is if you see p0335 or other similar codes, don't just go replacing the crankshaft position sensor.

    Any ideas why my 11 mustang gt will not successfully relearn the crankshaft position? Ive returned my idle, and other perimeters to stock and attempted the process numerous times. I get the error on my sct saying maximum attempts reached, restart procedure. Is this an inducation of a bad sensor?

    • @SchrodingersBox

      it’s possible the timing is off, there is incorrect signal input, or you are not reaching fuel cutoff.

  • @charliemagoo7943

    These will drive you crazy because the cam and crank are supplied by the same 12v in the pcm. I remember an 05 doesn't show they are shared but what happens is an oil leak at the top of the engine breaks the wires down and shorts out the 12v on the connector to the cam. Many times it only shows a crank sensor code but will be a no start. If that 12v is pulled down to about 8v it will make it run like poo or set 300 code

    I am having the same issue with my 2006 3500 15pax van. Runs decent when cold, VERY intermittent rough run/complete stall when warm. Currently has the P0335 code.
    Your thorough approach and detailed explanation is FANTASTIC! Thank you for sharing your knowledge with us! I will let you know what I find out tomorrow when troubleshooting, but using your scientific method, I am guessing a wiring short as well. Cheers from a 5280 native!

    Hi! I have a 2006 Chrysler Town and Country. I replaced the crankshaft sensor, no codes were popping up related to the sensor but I was just going down the line of parts for another situation...I am now in the position of the video, where the car is running worse and I now have codes 0339 and 0335. Is it the relearn process that is doing this? Blessings!

    • @SchrodingersBox
      @SchrodingersBox  Před 3 měsíci +1

      The relearn has nothing to do with sensor performance. It’s strictly for misfire calibration. Start with the basics and look at your sensor voltage from the signal as a basic first step.

      crank relearn is just for misfire counter timing. it won’t cause any of those issues. what evidence was it that the PCM was the problem? need to start there because it’s looking like the PCM was not the issue based on your description.

      It’s way easier to just check the signal at the PCM which is normally how I do it. I only removed the starter to show the connector for the video and of course I had to go there anyway for the repair but I really recommend checking the voltage from the PCM terminal.

    • @curtthompson2787
      @curtthompson2787 Před 3 měsíci
