P0025 - EXHAUST CAMSHAFT POSITION TIMING - OVER-RETARDED (BANK 2)

Description: This DTC sets when the variable camshaft timing (VCT) position is over-retarded. 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 Erratic camshaft position due to low oil pressure Oil flow restriction in the oil passages or the VCT valve body VCT22 solenoid valve stuck open VCT22 circuit open VCT22 circuit short to voltage VCT22 circuit short to ground VPWR circuit open Camshaft advance mechanism binding (VCT unit) Damaged VCT22 phaser Damaged camshaft position 22 (CMP22) sensor CMP22 sensor circuits open CMP22 sensor circuits short to voltage CMP22 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 Engine System, Oil Pressure Test, to check the engine oil pressure. Refer to the Engine, Timing Drive Components, to check the engine timing and VCT phasers.
