Inspection Method For Sensor Connectors Or Wires

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

   • If engine starts and runs, perform the following steps while idling engine.
3. Access PIDs for the switch you are inspecting.
4. Shake each connector or wiring harness a bit vertically and horizontally while monitoring the PID.

• If PID value is unstable, check for poor connection.
