Inspection Method for Sensor Connectors or Wires

1. Connect WDS or equivalent to DLC-2.
2. Turn ignition switch to ON position (Engine OFF).
   NOTE:

   • If engine starts and runs, perform the following steps during idle.
3. Access PIDs for the switch you are inspecting.
4. Slightly shake each connector or wiring harness vertically and horizontally while monitoring the PID.
   • If PID value is unstable, check for poor connection.
