IMPORTANT:
Perform the Circuit/System Testing in order to verify the integrity of the TC vane position sensor circuits before proceeding with the Component Testing.
TC Vane Position Sensor
- Remove the TC vane position sensor.
- Connect the TC vane position sensor harness connector.
- Ignition ON, observe the scan tool TC Vane Position Sensor parameter for a smooth percentage change while slowly depressing the button at the end of the TC vane position sensor. The percentage change should increment slowly without any spikes or dropouts.
- If the TC Vane Position parameter drops out or spikes, replace the TC vane position sensor.
