P0711Transmission Issues
Transmission Fluid Temperature Sensor A Circuit Range/Performance
P0711 means the transmission fluid temperature signal behaves outside the expected range or changes implausibly. Learn what to check before replacing parts.
What you may notice
Symptoms
- 01Warning light may illuminate
- 02Intermittent or implausible scan data
- 03Vehicle-specific symptoms may vary
Where to look first
Common causes
- 01A poor ground, connector corrosion, wiring fault, or temperature-sensor issue can distort the reading.
- 02Wiring, connector, or ground fault
- 03Vehicle-specific mechanical or control issue
A sensible sequence
Best diagnostic order
- 01Save codes and freeze-frame information
- 02Compare the temperature reading with ambient and operating conditions; inspect the sensor circuit, grounds, and connectors.
- 03Confirm readings with vehicle-specific specifications
- 04Verify the repair under the conditions that set the code
Step by step
What to check and repair
- 01Compare the temperature reading with ambient and operating conditions; inspect the sensor circuit, grounds, and connectors.
- 02Repair only the verified cause and retest

Related sensor or switch signal
- Typical behavior
- Plausible and consistent with the operating condition
- Possible clue
- An unexpected value or dropout helps localize the fault

What P0711 means
The transmission fluid temperature signal behaves outside the expected range or changes implausibly. The code identifies an observed condition; it does not prove which part needs replacement.
Diagnostic direction
Compare the temperature reading with ambient and operating conditions; inspect the sensor circuit, grounds, and connectors.
Before clearing the code
Save stored and pending codes and freeze-frame data. Use service information for the exact vehicle before repair, then confirm the issue no longer returns.
