Bad Camshaft Position Sensor Symptoms - How to Test and FIX!!

Автокөліктер мен көлік құралдары

Camshaft position sensor symptoms such as starting difficulties, stalling and erratic idle will often store faults codes including P0340, P0341, P0342, P0343 and P0344. But how do you know what’s really causing them? Camshaft sensor, wiring, engine ECU… the list goes on.
That’s why Tim’s here! In this episode he will take us through camshaft position sensor problems, testing and ultimately fixing the faults.

    It worked well. The radio and while making a Bluetooth call, they both would shut off for a few seconds and then come back on over and over, and I would lose power steering sometimes too. The check engine light came on and that's when I had Auto Zone give me a diagnostic trouble code, and it was showing the power train system, and ABS. Sure enough though, and the attendant tried to sell me a power train system for $456.90, but she made the mistake of saying that the codes just needed to be reset and that when I found this, and two other videos telling me to do this. Thank you very much!

    Very informtive and complete video! I got lucky! On my 2007 Murano, I used a 10mm ratching wrench and did not have to move the hose. Just before pulling the sensor, I blew out the connector and the sensor pins in place with electronics cleaner and all codes went away. So I never even had to pull the sensor! I was showing P0345(Camshaft Position Sensor Bank 2), P0725(Engine speed input circuit), P1701(Power supply circuit), P0868 (Transmission fluid low). The last 3 are Nissan OEM codes. I'm not smart enough to know if those should be all related, but I can see where all but the P0868 could be related, maybe? Anyway, Thanks for saving me time and money! I will update if any of them come back.😎

    Excellent video. I have a customer with four persistent fault codes for a wheel speed sensor and cam position sensor, instead of letting me perform tests to find the cause, he's purchased and had me install... 3 cam position sensors, and one wheel speed sensor... with no results. I'm hoping he'll allow me to actually diagnose the issue after the wheel speed sensor $$$$ didn't fix it... which I told him wouldn't fix it. I'm gonna send him this video, it explains the diagnostic process way better than me.

    I started my Fiat Ducato (2013 diesel) yesterday to drive it to the garage for a new timing belt + kit. It run badly, actually only ignition pulse to 2 of 4 cylinders. What else than a bad ECU can cause ignition pulse on 2 of 4 cylinders? What about a cam shaft position sensor or crank shaft position sensor? My garage said that they had never seen one of those bad and still being able to start the engine. Of course, all the cables need proper testing also, so far thay have found nothing wrong there, so they are suspecting the ECU/ECM. Any other leads? And, is all pulse signals 5V? I think they said they meassured 2V but I need to challange them on that because I have never heard of a 2V signal, only 5V but I am no car mechanich either.

I cleaned out fuel tank, replace fuel pump and fuel filter. I cleaned injectors. Car cranks has spark and fuel out the injectors. I thinking must be a sensor where the timing is not lining up with the spark and injected fuel. Any thoughts

I've seen references of between Harmonic Balancer & Timing Cover, in the Block above the oil pan, back of the block, or inside the Distributor. I've looked carefully, no loom wires, no port in timing cover, & I replaced the OEM Distributor with new OEM unit. Vehicle timing set to 4 degrees before TDC. Verified all spark plug & fuel inj. Vehicle starts, stalls, back fires.

    HI this is a really good Video (and Have looked dozens to try and understand and resolve Sensor Issues) very very clear and very well explained, I only have a couple of comments if you spoke just a little slower that would be great and also if there was a slightly more detail description on the different configurations of sensors wiring for example on BMW's the signal is the middle wire .. also maybe a test of the actual sensor using something metal and the fact cheap sensors are usually Crap and you can replace them and the fault can still exist, also if you drop a sensor there is a good chance it will be damaged and can throw up a an intermittent fault which you cannot really test with a meter. not criticisms observations and im please to have found a company that can service repair ECU etc you guys clearly know what your doing ... again really really good video with visuals and diagrams (I know how long it takes to produce something like this) keep up the videos and the great work your efforts are much appreciated..

    Hi. Yes you can test the sensor's internal resistance, however a good reading will differ depending on the specific sensor you are testing. If you would like to test the sensor this way then we would recommend getting the data sheet for your sensor to determine what a good or bad reading would be.

    Hi. If you have a reading that isn't battery voltage when testing the ground wire at the ECU, it could be that the wire is shorted to voltage. To test for this you should remove the ground wire's terminal from the ECU connector and test for voltage by placing the black probe on battery negative and the red probe on the removed terminal end of the ground wire. If there is any voltage displayed then there is a short to voltage affecting the ground wire which will need to be repaired. Hope this helps!

    Hi. There are a few different tests that you can conduct on the sensor to determine if it is faulty, but these can vary depending on what type of sensor you have and the manufacturer, so you would have to consult your vehicles schematic or repair manual in order to do this. Using the method we outline at 1:52 in this video, you can determine it is likely the sensor that is faulty if it has a good ground, good supply voltage and a good signal. Hope this helps!

    If you are getting any other fault codes alongside the P0391 then it is worth investigating them first as they could be causing the code. However, if you just have the P0391 then we would still recommend completing the checks outlined in this video to ensure the fault isn't with the sensor, wiring or ECU. If they all check out OK, then you could have a fault with mechanical components which will need to be investigated.

    Very good. But I can't get any codes on a crank no-start (Corsa C). Two pedal test gives continuous flashes-- I counted up to a hundred; two cheap readers, then an Xtool D7 (360€) which I bought specifically to find the problem. Have 50psi on fuel rail, new plugs, removed throttle body and cleaned, sprayed MAF with correct cleaner, changed crankshaft sensor. It just fires and cuts out. A whole ago it ran for a whole 30secs, then 10 secs, now nothing. Any ideas PLEASE?

    Hi. Apologies but I'm not sure we do say that in the video? At 2:46 we say if the wiring to the sensor is ok then the sensor itself is faulty. There are a few different tests that you can conduct on the sensor to determine if it is faulty, but these can vary depending on what type of sensor you have and the manufacturer, so you would have to consult your vehicles schematic or repair manual in order to do this.

    Hi. A P0365 indicates a problem with the Camshaft sensor 'B' circuit. If you have already replaced both sensors then we would recommend completing the circuit checks in this video from 1:52 onwards to determine if the sensor has a good ground, is receiving the correct power supply, and that it is outputting a good signal. The fault will likely lie with either the connector to the sensor, the wiring loom from the sensor to the ECU, or with the ECU itself. Hope this helps.

    Thanks for a very nice video! However I have problems with my sensor. It is a 2000 Volvo V40 and when reading the error code it says "ECM-32 Camshaft position (CMP) position sensor". So I checked the voltage from the ECU connectors according to your suggestion in the video and it was OK (+5V, +5V and battery voltage) so it should be the sensor. I then ordered a brand new sensor and replaced the old one and tried to erase the error code but it instantly comes back. I measured the resistance between pins on both sensors and it is exactly the same. Any suggestion how to proceed the investigation?

    Did you complete the voltage checks at the sensor connector as well as the ECU connector? If the voltages at the connector are bad then the fault could be in the wiring from the ECU to the sensor. Also did you replace the sensor with an OEM part? Sometimes aftermarket parts can cause functionality issues even if they are the same part number.

    @@Ecutestinglimited Today I measured the signal cable all the way from the transducer to the ECU connector and the cable was OK. Perhaps the error then is inside the ECU? I am starting to think that the error is due to bad cam shaft alignment. I will have a friend visiting me this week and he told me that when he was changing the cam belt on his V40 he manage to bend the tool holding the cam position just a little bit. He didn't notice that and when starting the engine he had exactly the same error code as I have. When adjusting the cam position the error disappeared. I have also checked the cam position and to me it looks like it is somewhat out of position so I have a small hope that this is the reason also for me. I will let you know as soon I know this for sure.

    Problem solved! Today a friend visited me and he could, without a doubt, say just by looking at the cam ends that the positions were wrong. He loosened one of the two cog wheels and adjusted the inlet cam so it aligned with the other cam end using a special tool. After adjustment and ignition on it was possible to clear the cam shaft error code and it has not (yet!) returned. I am very happy! I have no explanation how this could happen. The screw on the cog wheel was very tight (not loose anyway) and the cam belt look almost new since I have only driven 12000 km since the replacement. What on earth could have caused this?

  • @Ecutestinglimited

    @Ecutestinglimited

    Hi. This is due to the ECU having an internal pull up resistor which pulls the voltage up in the signal circuit to 5v. When the camshaft sensor is unplugged, the signal wire is not connected to anything that could pull it to a lower voltage so you get a measurement 5V on the signal wire with the ignition on, as the ECU is basically seeing an open circuit through the pull-up resistor.

However when the car became Hot ie in traffic and during hot weather now and then all the warning lights flashed, car staled , then I restarted it and it would be ok for a while.recently it did the same on and off.

    What’s the difference between camshaft and crankshaft?

  • @Ecutestinglimited

    @Ecutestinglimited

    Жыл бұрын

    Hi. A camshaft controls the opening and closing of the engine's valves due to 'lobes' or 'cams' pushing up against the valves as the camshaft rotates, which allows the intake of fuel-air mixture into the pistons as well as the release of exhaust gasses. The crankshaft converts the reciprocating motion of the pistons into rotational motion, transferring power to the transmission. It is connected to the pistons through connecting rods and converts the up-and-down motion into a circular motion. Both the crank and cam sensors monitor the rotational position and speed of each of these and relay this information back to the ECU for optimal and efficient valve timing and engine operation. Hope this help!
