Diagnostic Trouble Code (DTC) Charts and Descriptions
P052A - Cold Start Intake (A) Camshaft Position Timing Over-Advanced (Bank 1) (Continued)
Diagnostic Aids: 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, Timing Drive Components, to check the engine timing.

P052B - Cold Start Intake (A) Camshaft Position Timing Over-Retarded (Bank 1)
Description: This DTC sets when the variable camshaft timing (VCT) position is over-retarded during cold start up. This DTC
sets when the camshaft timing exceeds a maximum calibrated value or remains in a retarded position.
Possible Causes: • Camshaft timing incorrectly set
• Continuous oil flow to the VCT piston chamber
• Variable camshaft timing bank 1 solenoid 1 (VCT11) valve stuck open
• Camshaft advance mechanism binding (VCT unit)
Diagnostic Aids: 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, Timing Drive Components, to check the engine timing.

P052C - Cold Start Intake (A) Camshaft Position Timing Over-Advanced (Bank 2)
Description: This DTC sets when the variable camshaft timing (VCT) position is over-advanced during cold start up. This
DTC sets when the camshaft timing exceeds a maximum calibrated value or remains in an advanced position.
Possible Causes: • Camshaft timing incorrectly set
• Continuous oil flow to the VCT piston chamber
• variable camshaft timing bank 2 solenoid 1 (VCT21) valve stuck open
• Camshaft advance mechanism binding (VCT unit)
Diagnostic Aids: 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, Timing Drive Components, to check the engine timing.
