Can you please help me with the wire diagram for sensors crank and cam please? I need the pinout I.

I can see the 5v reference and my ground, but I don't have or see my 12v in the ECM.
Thank you so much in advance.

Hi,

As far as the problem, it looks like you are on the right track. It deals with the CKP circuit A. What I did is this. First, I attached the wiring schematic for the entire powertrain control circuit. I highlighted the wires from the CKP and CMP to make it easier for you to trace. Additionally, I highlighted the CKP and CMP sensor in the schematic.

Next, I included the diagnostics related to the code. They follow the schematics and are specific to the P0335.

Here is a link you may find helpful when testing wiring:

I hope this helps. Let me know what you find or if you have other questions.

Take care.

Joe

See pics below. Note: The schematics were a few pages long. I had to cut each page in half to make them readable for you. I did overlap them so you can follow from one to the next. Also, pic 7 starts the diagnostics. Pics 4 and 6 contain the sensors in question.

Update: so, I was doing a bypass test (test light connect to positive and tapping the signal wire with it) somehow the crankshaft position sensor woke up because now the RPMS gauge is working. But if I shut the car off the gauge stops what I find out that with the car idling if I tap or touch the Camshaft Sensor signal wire (back probe) the tachometer starts working and the car runs normal if I erase all the codes only the p0340 camshaft comes back I already changed the camshaft sensor.

Bypass test only worked for the crankshaft I can hear the relay activating, but when I did it for the camshaft, I didn't hear anything on the relay
Do you think is a short to ground?
Thank you for your help.

Hi,

If you were probing with 12v, check to make sure there isn't corrosion or something causing excessive resistance. The sensors should only be getting a 5v reference. As far as a short to ground, that won't fix itself when you use the test light.

Let me know what you find.

The sensor is getting 1.29 v.

Hi,

That should be 5v. Go to the ECM and check for corrosion, a pushed-in pin, a bent or broken pin, or anything that can cause a power issue.

Let me know what you find.
