P0711
ModerateP0711 — Transmission Fluid Temperature Sensor Malfunction
Description
What the code means
Code P0711 points to a problem with the transmission fluid temperature (ATF) sensor. The engine control unit (DME) sees the engine temperature change but no matching temperature change in the transmission. That points to a fault in the sensor circuit (open or short) or a failed sensor. The sensor measures ATF temperature and sends the signal to the transmission control module (TCM).
Symptoms
Symptoms
- Check Engine (or Service Engine Soon) light is on
- Possible shift problems (jerking, delayed shifts)
Causes and fixes
Diagnosis and repair
- Check the ATF temperature sensor circuit for an open or short.
- Inspect the sensor connector for poor contact.
- Replace the faulty ATF temperature sensor (OEM part number:
24107510506). - Clear the fault codes and take the car on a test drive.
Possible secondary damage
Consequences of ignoring the fault
Ignoring the fault can lead to:
- incorrect temperature readings,
- harsh shifts,
- transmission overheating,
- internal damage (worn clutch packs, damaged valve body).
