2003 Chrysler PT Cruiser Repair Question
Cam sensor
Asked by kariasmith22Answer
What trouble codes are you getting?
P0340. My mechanic is so confused at this point. I took it to Chrysler they said it was out of time, so I repaired that first and put a new sensor on. Still same problem. Then is would crank so we found out the heads had to be replaced. '
Here some tips I got for the problem. Check the wires shown in pictures for damage and breaks before you go on.
A broken wire would casue the code.
Where do I find the pictures of the wire that I need to have checked? The dealership said the wires were fine that's why they said it had to be the timing. But clearly it is not.
The camsensor consists of 3 wires. You need to test them for continuity between the sensor and PCM.
Black/Light Blue is the sensor ground which is linked to a few other sensors. Unplug Cam sensor and test for continuity to terminal # 22 of C2 connector at PCM.
Orange is 5 V supply, ensure voltage is present when ignition is turned on. If none, check wire for continuity to terminal # 29 of C2 connector at PCM.
Tan/Yellow is the CMP signal. Test for continuity to termianl # 34 of C2 connector ofPCM.
