P0016 - CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION - BANK 1 SENSOR A

Description:	The powertrain control module (PCM) monitors the variable camshaft timing (VCT) position for a misalignment between the camshaft and crankshaft. The test fails when the misalignment is 1 tooth or greater. This DTC can also set due to VCT system concerns (oil contamination or VCT solenoid stuck).
Possible Causes:	Camshaft timing incorrectly set Continuous oil flow to the VCT piston chamber Erratic camshaft position due to low oil pressure Oil flow restriction in the oil passages or the VCT valve body VCT solenoid stuck in position Open or short in the VCT circuit Open VPWR circuit Camshaft advance mechanism binding (VCT unit) Damaged VCT phaser Damaged camshaft position (CMP) sensor Open or short in the CMP sensor circuits Radio frequency interference
Diagnostic Aids:	These DTCs may be accompanied by other DTCs. Diagnose all CMP sensor DTCs first. If no CMP sensor related DTCs are present, continue to follow diagnosis for the DTC. This DTC is a functional check of the VCT unit. Diagnose any base engine concerns related to the engine oil pressure or engine timing. Refer to the appropriate Engine System article, Oil Pressure Test , to check the engine oil pressure. Refer to the appropriate Engine article, Timing Drive Components , to check the engine timing and VCT phasers.
