About a year ago I got a bad cam sensor code and, after replacing the cam sensor with an OEM unit the cPCM odes did not reappear.

After a new PCM was replaced last week at the GM dealer, however, they now tell me the car is throwing a bad cam sensor code.

After thinking about this awhile, I suspect it may be a broken valve spring that is causing the cam sensor code to go off.

Any thoughts here?

Thanks

You sure it is the cam sensor code and not the Crank sensor relearn code...

the GM dealer tells me it is a cam senor and not a crank sensor code?

weird hey?

if you have a broken valve spring you'll hear it... I would find someone that can do a crank relearn procedure on the new PCM and see if it goes away (anyone w/HP Tuners or EFI Live can do a relearn)
