P0711: Transmission Fluid Temperature Sensor Circuit Range/Performance
Can you still drive? Yes, but the transmission may shift roughly or not engage the torque converter lockup. Avoid extended highway driving and heavy towing until repaired.
What Does P0711 Mean?
Code P0711 indicates that the transmission fluid temperature sensor is providing readings outside the expected range for current operating conditions. The TCM compares the TFT sensor reading to other temperature sensors at startup and during operation. If the readings do not correlate logically, this code is set.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.

- Degraded transmission fluid temperature sensor
- Old or contaminated transmission fluid affecting sensor accuracy
- Intermittent wiring connection at sensor
- Sensor reading stuck at one value
- Air pocket near sensor causing inaccurate readings
Symptoms
- Check engine light on
- Inconsistent transmission shifting
- Delayed engagement when shifting into Drive or Reverse
- Transmission may not lock torque converter
- Reduced fuel economy
Diagnostic Steps
- 1Compare TFT sensor reading to engine coolant temperature after cold soak
- 2Monitor TFT reading as vehicle warms up to verify it changes logically
- 3Check for a sensor reading that is stuck or changes too slowly
- 4Inspect sensor connector for intermittent contact issues
- 5Check transmission fluid level and condition
- 6Test sensor resistance at known temperatures against specifications

Frequently Asked Questions
How can I tell if the sensor or the fluid is the problem?
Start by checking fluid condition. If the fluid is dark, burnt, or has not been changed in a long time, service the fluid first. If the code returns with fresh fluid, the sensor is likely at fault.
Is P0711 the same as P0710?
No, P0710 indicates a complete circuit malfunction, while P0711 means the sensor is working but providing readings outside the expected range. P0711 often indicates a degraded sensor.
