MONITOR DESCRIPTION

The ECM optimizes the intake valve timing using the Variable Valve Timing (VVT) system to control the exhaust camshaft. The VVT system includes the ECM, cam timing oil control solenoid assembly, camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) and camshaft timing exhaust gear assembly. The ECM sends a target duty-cycle control signal to the cam timing oil control solenoid assembly. The camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) is operated to control the oil pressure supplied to the camshaft timing exhaust gear assembly based on this signal. The camshaft timing exhaust gear assembly can advance or retard the exhaust camshaft.

If the difference between the target and actual exhaust valve timing is large, and changes in the actual exhaust valve timing are small, the ECM interprets this as the camshaft timing exhaust gear assembly stuck malfunction and stores a DTC.


DTC P001400 and P002400 (Advanced Camshaft Timing) is subject to 2 trip detection logic.

DTC P001500 and P002500 (Retarded Camshaft Timing) is subject to 1 trip detection logic.

These DTCs indicate that the camshaft timing exhaust gear assembly cannot operate properly due to a camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) malfunction or the presence of foreign matter in the camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]).

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform steps [F] through [H].

  14. Repeat the pattern of accelerating the vehicle from rest to approximately 60 km/h (37 mph) and then decelerating the vehicle 10 to 15 times [F].

  • If DTC P001400 or P001500 is output, check the VVT system (for exhaust camshaft of bank 1) circuit.

  • If DTC P002400 or P002500 is output, check the VVT system (for exhaust camshaft of bank 2) circuit.

  • Bank 1 refers to the bank that includes the No. 1 cylinder*.

    *: The No. 1 cylinder is the cylinder which is farthest from the transaxle.

  • Bank 2 refers to the bank that does not include the No. 1 cylinder.

  • DTC P001400, P001500, P002400 or P002500 may be stored when foreign matter in the engine oil is caught in some parts of the system. The DTC will remain stored even if the system returns to normal after a short time. This foreign matter may then be captured by the oil filter.

  • Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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.
