On the 2011 Chevy Malibu with the 2.4L engine, the P0017 code is pointing to a problem with the Crankshaft-to-Exhaust Camshaft correlation. First thing to check here is the timing chain. Many times the chain can stretch or jump slightly which can cause the correlation issue. Make sure the timing marks are still set dead-on perfect. Even the slightest bit off can set this code.
If the timing marks check ok, then this can be a problem with the Camshaft Position Actuator Solenoid. This solenoid is used in the variable valve timing system. The solenoid advances/retards the ignition timing to provide the best fuel economy and engine performance for any given driving condition. When the solenoid does not move the camshaft to the spot expected by the on-board computer, this code will set. The solenoid is located on the top, passenger’s side of the engine. It is the rear-most of the two solenoids.
