Pontiac Grand Am GT: Camshaft..(service engine came..running fine

This answer was rated:

I have a Pontiac Grand Am GT, My car needed the Camshaft positioning sensor replaced (service engine came on, took it in to have the light read and it was that sensor). Everything was fine, she was running great, then the light came back on not even a day later. She is still running fine, but i replaced the part.... so i am very confused on why i am still throwing that light.

Could you please provide me with the exact code it is setting

If the cam sensor is changed and you continue getting the code


you need to check the engine wiring harness and the cam sensor connector


a bad PCM can also trigger this code


I am attaching information regarding p0341 and some testing


the information follows:


Vehicle Application:
2000 Pontiac Grand AM 3.4L, Vin E, Eng Cfg V6
Customer Concern:DTC P0341 New Camshaft Position Sensor (CMP) sensor tried-same.
Tests/Procedures:1. Test for 12 volts power to the cam sensor on the Red/White wire.

2. Pin "C" at the cam sensor should be a good ground.

3. Pin "B" is the signal back to the Powertrain Control Module (PCM) and should be a 0-12 volt square wave.

4. If voltages are incorrect, inspect the wire harness for rubbing or opens.

5. If there is a good 0-12 volt signal at the PCM, it has a bad PCM.
Potential Causes:Camshaft Position Sensor (CMP)
Powertrain Control Module (PCM)
Wiring Connector
Diagnostic Codes:P0341


you will need a scope to check for square wave


let me know how these tests work out
