If any DTCs other than P001100 or P001200 are output, troubleshoot those DTCs first. P001100 or P001200 and other DTCs are output When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.ĬHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P001100 OR P001200) The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. That foreign matter may then be captured by the oil filter. The DTC will remain stored even if the system returns to normal after a short time. If the difference between the target and actual intake valve timing is large, and changes in the actual intake valve timing are small, the ECM interprets this as the camshaft timing gear assembly stuck malfunction and stores a DTC.ĭTC P001100 or P001200 may be stored when foreign matter in the engine oil is caught in some parts of the system. The camshaft timing gear assembly can advance or retard the intake camshaft. The camshaft timing gear bolt (intake camshaft timing oil control valve) is operated to control the oil pressure supplied to the camshaft timing gear assembly based on this signal. The ECM sends a target duty-cycle control signal to the cam timing oil control solenoid assembly (for intake camshaft). The VVT system includes the ECM, cam timing oil control solenoid assembly (for intake camshaft), camshaft timing gear bolt (intake camshaft timing oil control valve) and camshaft timing gear assembly. The ECM optimizes the intake valve timing using the VVT (Variable Valve Timing) system to control the intake camshaft.
