2011 GMC Terrain P0017 Exhaust Camshaft Bank1

2011 GMC Terrain P0017 Exhaust Camshaft Bank1

GMC Terrain On the 20011 GMC Terrain with the 3.0L engine, the P0017 points to a problem with the crankshaft and exhaust camshaft for bank1 being out of sync. This is more commonly due to a faulty Camshaft Position Actuator Solenoid Valve. This valve plays a role in the variable valve timing system. This system advances/retards the timing to provide the best fuel economy and performance for any given driving condition. When the valve isn’t working properly, the cam-crank will be out of sync. More times than not, then get clogged…

2012 Chevy Malibu 2.4L P0016

2012 Chevy Malibu 2.4L P0016

Chevy Malibu On the 2012 Chevy Malibu with the 2.4L engine, the P0016 is a fairly straight forward code pointing to a problem with the Camshaft Position Actuator Intake Solenoid Valve. This solenoid plays a role in the variable valve timing system. This system retards or advances the ignition timing to provide the best performance and fuel economy for any given driving condition. So when faulty, this can interfere with correct ignition timing. This can produce performance issues as well as poor fuel economy. The solenoid tends to get clogged with build-up…

2009 GMC Acadia P0017 Cam-Crank Correlation

2009 GMC Acadia P0017 Cam-Crank Correlation

GMC Acadia 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…

2009 Chevy HHR P0013 P0014

2009 Chevy HHR P0013 P0014

Chevy HHR On the 2009 Chevy HHR, the P0013 and P0014 are pointing to a problem with the Exhaust Camshaft Position Actuator Solenoid (aka “Variable Valve Timing Solenoid”). These are actually fairly common fail items. They tend to get clogged and fail. The solenoid is located on the top, passenger’s side of the engine. Exhaust side is the one closest to the rear of the engine. Inspect the electrical connector and wire harness for any loose, broken or damaged wires. If no problems are found, most commonly, the solenoid will need…

2008 Cadillac STS P0008 Timing

2008 Cadillac STS P0008 Timing

Cadillac STS On the 2008 Cadillac STS, the P0008 is “Engine Position System Performance Bank 1”. The engine control module (ECM) tests for a misalignment between both camshafts on one bank of the engine and the crankshaft. The misalignment would be at an idler sprocket for either bank or at the crankshaft. Once the ECM learns the position of both camshafts on one bank of the engine, the ECM compares the learned values to a reference value. The ECM will set this DTC if both learned values for one bank…
