On the 2009 GMC Acadia, the P0017 points to a problem with the camshaft-crankshaft correlation on bank 1 exhaust side. There is a “known issue” on the 3.6L engine on this year when a “correlation” code sets. The 3.6L is very well known for the timing chain to “jump” due to a problem with the chain and/or the chain tensioner. However- when this is the case, more times than not, there are multiple correlation codes (P0017 – P0021). So, if this is the only code set, best place to start here is with the Camshaft Position Actuator Solenoid for exhaust/bank1. The actuator is on the passenger’s side of the engine, towards the rear, just above the water pump pulley. If replacing the solenoid does not solve the problem, then unfortunately, the chain and tensioner will need to be inspected and checked for any problems and that ignition timing is still set correctly.
