On the 2012 Buick LaCrosse with the 3.6L engine, the P0014 is stating there is a problem with the Exhaust Camshaft Position System Performance for Bank 1. This is more commonly due to a faulty Camshaft Position Actuator Solenoid Valve (aka “Variable Valve timing solenoid”). More times than not, they get clogged and cannot achieve their expected min/max positions. This solenoid is located on the passenger’s side of the engine, towards the rear of the engine. The exhaust solenoid is the lower of the two solenoids. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires. Inspect the oil level and make sure it is full. If no problems are found, you can “try” to clean the solenoid. You can clean the valve with some throttle cleaner. Spray the valve trying to free up as much build-up as you can. Make sure it is dry before installation. However, more times than not this does not solve the problem and replacement will be necessary. To gain the clearance needed to remove the mounting bolt, the engine may need to be raised. To raise the engine, you will need to remove the side mount and slightly lift the engine. Use a floor jack with a piece of wood on it under the oil pan. Do not put the jack directly to the pan without the wood, as damage can occur. Remove the mount and then slowly and slightly jack the engine up until the bolt clears. Once the bolt is removed, use a twist-and-pull method to remove the solenoid.
