id051721292700
On-Vehicle Inspection
1. Inspect the power supply circuit for the intermediate sensor.
- (1) Set the battery and battery tray out of the way.
- (2) Disconnect the intermediate sensor connector.
-
- (3) Switch the ignition to ON (engine off).
- (4) Measure the voltage at intermediate sensor connector terminal A (harness-side).
-
-
• If there is any malfunction, repair wiring harness between AT mai relay and intermediate sensor.

- (5) Switch the ignition to off.
- (6) Connect the intermediate sensor connector.
2. Inspect the GND circuit for the intermediate sensor.
- (1) Switch the ignition to off.
- (2) Measure the voltage at intermediate sensor connector terminal C (harness-side).
-
-
• If there is any malfunction, repair wiring harness between intermediate sensor and GND.
