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

  • Wire 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.
