Transmission fluid temperature sensor: Diagnostics
In the event of a fault in the temperature sensor, three different diagnostic trouble codes may be generated:
- If the temperature increases or decreases too slowly during the first 15 minutes of driving, diagnostic trouble code P0711 will be generated.
- In the event of short to B-, diagnostic trouble code P0712 will be generated.
- In the event of short to B+ or an open circuit, diagnostic trouble code P0713 will be generated.
