P0016 - Crankshaft Position - Camshaft Position Correlation - Bank 1 Sensor A

4-6 Powertrain DTC Charts and Descriptions

Diagnostic Trouble Code (DTC) Charts and Descriptions

P0016 - Crankshaft Position - Camshaft Position Correlation - Bank 1 Sensor A (Continued)

• VCT11 circuit open

• VCT11 circuit short to voltage

• VCT11 circuit short to ground

• VPWR circuit open

• Camshaft advance mechanism binding (VCT unit)

• Damaged VCT11 phaser

• Damaged camshaft position bank 1 sensor 1 (CMP11)

• CMP11 sensor circuits open

• CMP11 sensor circuits short to voltage

• CMP11 sensor circuits short to ground

• Radio frequency interference

Diagnostic Aids: This DTC 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 this 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 Workshop Manual Section 303-00, Engine System, Oil Pressure Test, to check the engine oil pressure. Refer to the Workshop Manual Section 303-01, Engine, to check the engine timing and VCT phasers.

P0017 - Crankshaft Position - Camshaft Position Correlation - Bank 1 Sensor B

Description: This DTC sets when a misalignment between the camshaft and crankshaft is detected. This DTC sets when the

misalignment is 1 tooth or greater. This DTC can also set due to variable camshaft timing (VCT) system concerns (oil contamination or VCT solenoid stuck).

Possible Causes: • VCT unit to camshaft alignment

• 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

• Variable camshaft timing bank 1 solenoid 2 (VCT12) stuck in position

• VCT12 circuit open

• VCT12 circuit short to voltage

• VCT12 circuit short to ground

• VPWR circuit open

• Camshaft advance mechanism binding (VCT unit)

• Damaged VCT12 phaser

• Damaged camshaft position bank 1 sensor 2 (CMP12)

• CMP12 sensor circuits open

• CMP12 sensor circuits short to voltage

• CMP12 sensor circuits short to ground

• Radio frequency interference

P0018 - Crankshaft Position - Camshaft Position Correlation - Bank 2 Sensor A

Description: This DTC sets when a misalignment between the camshaft and crankshaft is detected. This DTC sets when the

misalignment is 1 tooth or greater. This DTC can also set due to variable camshaft timing (VCT) system concerns (oil contamination or VCT solenoid stuck).

Possible Causes: • VCT unit to camshaft alignment

• Excessive camshaft timing chain wear

• 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

• variable camshaft timing bank 2 solenoid 1 (VCT21) stuck in position

• VCT21 circuit open
