Customer Question
Does the cam positioning...

Does the cam positioning sensor on a LLY 2005 Duramax have to be programmed when changed

Mechanic's Assistant: Which particular sensor are you asking about? And have any trouble codes been triggered?

It's the sensor mounted down by the crankshaft and yes there is codes

Mechanic's Assistant: What is the model of your '05 Chevy?

2500 HD 4 door 4wheel drive SLT Sierra

Mechanic's Assistant: Are you fixing your Sierra yourself? What have you tried so far?

I'm not a mechanic I took my truck to a garage and he said it was that sensor, he has replaced it 2 times with a GM original part and when replaced my truck won't start. When he puts back my original sensor, same part number it starts, but every once in a while I get the code and it runs rough

HI,

No, the cam position sensor does not require any programming or relearn procedure when replaced.

If I can get the exact fault codes, I can check for any service bulletins or other causes besides the cam sensor
