P0711 Code: Transmission Fluid Temperature Sensor A Circuit Range/Performance
🟠 Moderate severity · drivable
You can drive, but the transmission may shift oddly or lock into a fail-safe gear until the sensor problem is fixed.
What P0711 means
The transmission fluid temperature sensor is reading temperatures that don't make sense, or it's changing temperature too slowly. The computer uses this sensor to protect the transmission from overheating and to adjust shifting. A bad reading can cause odd shifts or put the transmission into a fail-safe mode.
Symptoms
- Check engine light is on
- Harsh or delayed shifts
- Transmission may go into fail-safe (limp) mode
- Transmission may run hotter than normal
Common causes
- most common: Faulty transmission fluid temperature sensor
- common: Low or dirty transmission fluid
- common: Damaged wiring or loose connector
- less common: Internal transmission damage
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Check transmission fluid level and condition | Yes | $10–40 |
| Replace the transmission fluid temperature sensor | Mechanic | $150–400 |
| Repair damaged wiring or connector | Mechanic | $80–250 |
Frequently asked questions
Can I drive with a P0711 code?
Yes, but the transmission may shift oddly or lock into a fail-safe gear to protect itself. Get it checked soon, especially if the fluid is low or dirty.
What does the transmission fluid temperature sensor do?
It measures how hot the transmission fluid is. The computer uses that reading to protect the transmission from overheating and to adjust shift behavior.
How much does it cost to fix a P0711?
Replacing the temperature sensor usually runs $150–$400 including parts and labor. If it's just low fluid, a top-up costs much less.
