Code P0016 Pontiac Description

The P0016 code for Pontiac vehicles indicates a problem with the correlation between the crankshaft position sensor and the camshaft position sensor in Bank 1 Sensor 'A'. This means that the Engine Control Module (ECM) is detecting that the timing between the crankshaft and camshaft is not in sync as it should be. This can lead to a variety of performance issues and potentially cause further damage to the engine if not addressed promptly.

Tech Notes for P0016 Pontiac

If this Diagnostic Trouble Code (DTC) started after recent internal engine repairs, inspect for proper engine mechanical timing. With the camshaft cover removed and the #1 cylinder at top dead center, make sure that the darkened chain links are lined up with the alignment marks on the exhaust and intake cam sprockets.



If a P0016 is resetting without any engine performance concerns but the above information did not isolate a cause for the DTC, replace the Cam Phaser Actuator sprocket.
