P2822 Pressure Control Solenoid "J" Electrical (Shift Solenoid Valve SLP) While the vehicle is driven, an open or a short is detected in the shift solenoid valve SLP circuit for 1 second or more (1 trip detection logic).

  • Wire harness or connector

  • Continuously variable transaxle assembly (Shift solenoid valve SLP)

  • ECM

 Comes on DTC stored

MONITOR DESCRIPTION

This DTC indicates an open or short in the shift solenoid valve SLP circuit. If there is an open or short in the shift solenoid valve SLP circuit, the ECM detects the malfunction, illuminates the MIL and stores this DTC.

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLP)


    1. A001UYDC11
      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the C40 transmission wire connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 (SLP+) - 9 (SLP-) 20°C (68°F) 5.0 to 5.6 Ω
      3 (SLP+) - Body ground and other terminals Always 10 kΩ or higher
      9 (SLP-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    1. A001YB2C13
      *a

      Front view of wire harness connector

      (to ECM)

      Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      C63-39 (SLP+) - C63-38 (SLP-) 20°C (68°F) 5.0 to 5.6 Ω
      C63-39 (SLP+) - Body ground and other terminals Always 10 kΩ or higher
      C63-38 (SLP-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
