MONITOR DESCRIPTION

These DTCs are stored when a malfunction is detected in the speed sensor (crank shaft position sensor) circuit. If there is an open or short in the speed sensor (crank shaft position sensor) circuit, or the speed sensor (crankshaft position sensor) signal is abnormal when the ignition switch is turned to ON or the engine is running, the ECM will store a DTC.

PROCEDURE

  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0315, P0335, P0336, P0337, P0338, P0339 AND/OR P1377)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

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

    5. Check for DTCs.

      Powertrain > Engine > Trouble Codes
