 Trouble Area
P2822

  1. The vehicle is being driven.

  2. An open or short in the shift solenoid valve SLP circuit is detected.

  3. 1 second or more

  4. 1-trip detection logic

  • Harness or connector

  • Continuously variable transaxle assembly (Shift solenoid valve SLP)

  • ECM

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 problem, illuminates the MIL and stores this DTC.

      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the 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

    NG
