DTC P0014-00_ Exhaust CMP Timing Over-Advanced: Notes

DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0014:00	Exhaust CMP timing over-advanced
DETECTION CONDITION	The actual exhaust valve timing is over-advanced by specification from the target exhaust valve timing for specified period when the oil control valve (OCV) is controlled in the feedback mode. MONITORING CONDITIONS ECT: above 60°C {140°F} Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Performs the exhaust variable valve timing control with a maximum cam retard request.
POSSIBLE CAUSE	Low engine oil pressure Loose timing chain or improper exhaust valve timing due to timing chain slippage OCV malfunction Spool valve in OCV is stuck in advanced position Engine oil runners are clogged or have leakage: Between oil pressure switch and OCV Between OCV and hydraulic variable valve timing actuator In hydraulic variable valve timing actuator PCM malfunction
