What does engine code mean on the p0014 chevy equinox?

P0014 is the OBD-II generic code that the engine control module (ECM) has determined that the bank 1 exhaust camshaft is more advanced than what the ECM has commanded it be. This over-advanced condition could be during advancing or retarding of the camshaft timing.But what does the ECM actually do. Well it essentially functions as the main computer for many of the vehicle's engine performance and drivability functions. The ECM takes the information from the engine's various sensors, and uses that information to calculate and tune engine spark and fuel for maximum power and efficiency. The cost for a new ECM will typically be around $800, with labor around $100, bringing the average total expense for an ECM replacement to approximately $900.
