MONITOR DESCRIPTION

The camshaft position input to the ECU is used to determine engine phase, enable sequential fuel injection control and to determine camshaft position for VVT control. The inlet camshaft has three 'teeth' spaced 90° apart, which are detected by the electromagnetic sensor. The valve timing setting is measured in the ECU by measuring time from a (fixed position) crankshaft tooth to a (variable position) camshaft tooth. As the engine speed and the position is known from the crankshaft sensor signal, the camshaft position can be calculated.

CAUTION / NOTICE / HINT

Tech Tips

Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. 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.

PROCEDURE


  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0366)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Trouble Codes.

    5. Check for DTCs.

      Result
      Result Proceed to
      DTC P0366 is output A
      DTC P0366 and other DTCs are output B

      Tech Tips

      If any DTCs other than P0366 are output, troubleshoot those DTCs first.

  2. CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR (FOR EXHAUST CAMSHAFT) - ECM)


    1. Disconnect the B31 camshaft position sensor (for exhaust camshaft) connector.

    2. Disconnect the B143 ECM connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      B31-1 (VVE+) - B143-29 (EV1+) Always Below 1 Ω
      B31-2 (VVE-) - B143-22 (EV1-) Always Below 1 Ω
      B31-3 (VC2) - B143-5 (VCV1) Always Below 1 Ω
      B31-1 (VVE+) or B143-29 (EV1+) - Body ground and other terminals Always 10 kΩ or higher
      B31-2 (VVE-) or B143-22 (EV1-) - Body ground and other terminals Always 10 kΩ or higher
      B31-3 (VC2) or B143-5 (VCV1) - Body ground and other terminals Always 10 kΩ or higher
