2008 Cobalt with P0016 Code.

Hi - My 2008 Cobalt LT with 2.2L L4 is pulling a P0016 Crankshaft position/camshaft position code. (Approx 137K miles)

I replaced the Camshaft Position Sensor with ACDelco #213-1690, cleaned the sensor socket and changed the oil. It's still throwing the code.

Any ideas? Could it be a ground issue? if so, any recommendations on where to look for the bad ground?

I can't get a Mass Inspections with the CEL.

Thanks.

You might have an issue with the crankshaft sensor, not the camshaft sensor.

I had the same code and it was the VVT Valve I changed both intake and exhaust took 10 minutes and it cleared my code. Before you bring it back for inspection you need to do a few drive cycles to reset the computer. I hope this helps.

So I just reread your initial post. Your code is for a camshaft position sensor not a crankshaft position sensor like you first stated. With that being said I now retract my first response regarding a possible bad crankshaft sensor.

Since yours is a 2008 2.2L you should have the L61 engine, which does not have VVT and therefore no intake/exhaust valve solenoids like on the 2009+ LAP engine. If you haven’t fixed your issue yet there is a strong possibility that your timing chain assembly needs to be replaced. The components can be worn out causing the timing to be slightly off.
