no no garage mechanic or even dealership gonna spend 10 min doing any of this !! meter electrical trblshooting.. ever. never never they gonna just rip out the sensor, wires and or Ecu and give u a huge $$ bill .. tell ya see ya goodluck.. Next. here in USA smfh
here's one for you, using a three wire on the crank. I'm getting a crank but no start with intermittent spark - side note while testing for spark I don't receive any cylinder misfires. but I'm also not getting any codes related to crank or cam. but I do get the barometric pressure one for having it disconnected while trying to start to make it easier.
Need help. Car would not start when hot, got the fault code P0335, fitted CPS, car run but fault came back, so re-fitted CPS but now won't rev over 2500rpm, when it hits those revs it gets a 'bang' in exhaust and then cuts out. Fault code P0335 then comes on.
Hi. The P0339 fault code indicates the ECU is detecting an intermittent or erratic signal from the crankshaft sensor. This can be due to a faulty sensor, ECU or wiring from the sensor to the ECU. We would recommend completing all the checks outlined in this video to determine where the fault lies. As the P0339 code is intermittent, we would recommend completing all these checks whilst wiggling the wiring loom and connectors from the ECU to the sensor to see if the voltage readings change at all. Hope this helps!
Hello, Thanks for a great test video. I am working on a custom LS1 Harness bought in 2004 direktly from GM ( New crate engine, Hardness and ECU ) Now I Have crancshaft position sensor ( P0336 ) error code, I hav changed sensor 2 times, before I saw your Video. I Now Have Cheched 5 V connetor to be 10,9 V , signal terminal has 10 mV and Ground connection has 12,2 V - After hearing what you say I suspect that the problem is inside the ECU, will you agree ?
Hi. Although this video is for a 3 wire sensor, you can follow a similar method of testing to diagnose the fault. Were the 2.34v readings taken from the sensor connector (with the sensor unplugged) with the ignition on? Start here and then follow the video to conduct the same tests at the ECU connector and so on.
I have p0726 code on audi a3 2.0 tdi 2005 I changed crankshaft sensor but the car its the same shut down and indicator light its open and something is shut down Is this test voltage the same to my car or not ? Whats is the problem? Any solution?
@ecutestinglimited can you help me here. Ford edge...installed new crankshaft sensors and the code for bank A is still on. I set my meter to 20v and tested the connector. Both holes gave me only .02 That a bad wire harness?
Hi, i am working on 2009 hyundai santa Fe. i have no spark and no fuel. But the problem is that i dont have any code on the car. The car would crank, i test the fuel pump, and it's good. I replaced the crankshaft position sensor as well as the pcm. But the car still doesn't have a spark.. what shld i do next??
one suggestion. for wire faults use a 250mA or 500 mA test light at least. A wire with one strand will still show continuity, but won't allow current to pass through it. A dim glow will expose this.
Thanks for this video. Moreover, I am working on a 2009 toyota corolla, I have 12volts on the ground wire of the crankshaft sensor, but am not getting any volts on the hot wire,I checked the continuity of the hot wire from the pcm to the terminal and resistance is ok but still won't get any voltage on the hot wire,I am confused now , any advice to what to do next?? Thanks
Could you do a similar video for a 2 wire sensor please? This is a great video but all of the vehicles I've worked on are 2 wire. I'm having issues currently with a 2008 5.4 3v F150. I love how you get right to the point and make things easy to understand. Thank you.
Hi. While it's more common for crankshaft position sensors to use a 5V signal, some can be 12V. Inductive type sensors are more likely to have a 12V signal, especially in older vehicles or if the sensor is a 2-wire design (compared to the 3-wire design more typical for 5V sensors). We would always recommend consulting your specific vehicle's technical documentation to confirm.
Hi. Yes a bad ECU can result in no signal from the crank sensor. If you have completed all the checks in this video to rule out the wiring loom and sensor, then it is worth testing the ECU to make sure it has a good power and grounds, which you can do by following the steps in our video here: th-cam.com/video/Y3aoD5BMxQw/w-d-xo.htmlsi=veJToJJYZVkvXI2I If you aren't getting any CAN communication it could also be worth testing the CAN Bus circuit. If you rule these out then you can determine your ECU is causing the issue. If this is the case then please contact our technical support team via email on info@ecutesting.com with the part number of your unit and any relevant diagnostic information, and they will advise you of any testing and re-build service we can provide. Thanks.
i Have a Honda accord 2005 Hybrid with code P0335 i change the crankshaft sensor but still have the code , check Volt on the blue cable and is 3.7V intead of 5V , what should a check next?
Hi. Do you know if your blue cable is the power supply to the sensor or the signal wire? And did you conduct this test with the ignition on or with the engine running?
If you have 3.7v on the signal terminal with the sensor disconnect and ignition on, then we would recommend completing the same test at the ECU connector by back probing the signal wire that goes to the crank sensor. If the voltage is 3.7v here, then the fault likely lies with your ECU, or both the wiring and ECU. Inspect the ECU connector for any damage, corrosion or poor terminal tension to see if the fault is being caused by a bad connection. If that checks out ok, then follow the steps in the video from 5:27 onwards (but on the signal wire instead of the 5v wire as shown in the video) to determine if the fault lies in both the wiring and ECU or just ECU. Hope this helps!
Hi. A P0016 can be caused by either a faulty cam or crank sensor, or a mechanical fault on the vehicle. We would recommend completing all the wiring checks in this video as well as our video on the cam sensor: th-cam.com/video/FTY11IeWBsk/w-d-xo.html in order to determine if the fault could lie in the circuit.
Hi. Yes, testing at the camshaft position sensor is largely the same as the crankshaft. We have done a video specifically on the cam sensor here: th-cam.com/video/FTY11IeWBsk/w-d-xo.html But if you aren't getting any voltage at the sensor connector with the ignition on and sensor unplugged, it is likely the wiring or ECU is faulty. You will need to back probe the wires at the ECU connector as we show in this video at 4:47. Hope this helps
@@Ecutestinglimited I have 12.4 volts at the ecm sensor wire brn/wht so it's got to be a break in the wire, so I ordered a short/open tester to find it. Thanks,
Hi. A P1335 on an Astra indicates a problem with the crankshaft position sensor, its wiring, or the ECU, so we would recommend completing the checks we have outlined in this video in order to identify and rectify the problem.
Hi i have got vw golf 1.2 tsi ,its keep giving code p0322 engine no speed,checked the wiring its showing 5v,signal wiring 5v,have changed 2 sensors still showing same problem.can u help plz
Hi. The P0322 code could also be caused by a fault with the Camshaft position sensor, have you completed the same tests at both the crank and cam sensor connectors? Also, have you tested the ground connection to the sensors as well? If you have done these, then also inspect the sensor connectors for corrosion or poor terminal tension. Hope this helps!
@@muhammadrashidjaved301 No, 4.9v is a good reading. If you have changed both sensors and the fault still remains then it could be the incorrect sensor for the vehicle, make sure you are buying OEM replacements specific for your vehicle. Again, it could be the ground wire is shorted to voltage, or a poor connection between the sensor connector and the sensor itself, so we would recommend completing these checks.
