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 over time. A system flush can help the problem, but it’s usually not a permanent fix. More times than not, the Camshaft Position Actuator Intake Solenoid Valve needs to be replaced. The solenoid is located on the top, passenger’s side of the engine. Just to the side if ignition coil #1. It is the front one of the 2 solenoids.
