DTC P052B: - Cold Start Camshaft Position Timing Over-Retarded (Bank 1)

DTC P052B: - COLD START CAMSHAFT POSITION TIMING OVER-RETARDED (BANK 1)

Description:	The powertrain control module (PCM) monitors the variable camshaft timing (VCT) position for over-retarded camshaft timing during cold start up. The test fails 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 VCT solenoid 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 ENGINE SYSTEM - GENERAL INFORMATION , Oil Pressure Test, to check the engine oil pressure. Refer to the TIMING DRIVE COMPONENTS - CAMSHAFT DRIVE CASSETTE, LH , to check the engine timing.
