DTC P0012:00	CMP timing over-retarded
DETECTION CONDITION	The actual valve timing is over-retarded by 10 ° from the target valve timing for specified period when the OCV system control is within the feedback range. MONITORING CONDITIONS Engine speed: below 4,000 rpm Engine coolant temperature: 60-110 °C {140-230 °F} Diagnostic support note This is a continuous monitor (CCM). The MIL 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 the first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Low engine oil pressure OCV malfunction Spool valve in the OCV is stuck in retard position Timing chain misinstallation The following engine oil runners are clogged or have leakage: Between the oil pressure switch and the OCV Between the OCV and the variable valve timing actuator In the variable valve timing actuator PCM malfunction
