P0711

Transmission Fluid Temperature Sensor A Circuit Range/Performance

Q: Is it safe to drive with P0711?

Short term, usually yes, but the transmission may shift harshly and skip converter lockup, which runs it hotter. Avoid heavy loads and repair it before it causes wear.

Q: Can I just clear P0711?

It will return once the module sees the implausible temperature again. Check the fluid and sensor rather than just clearing the code.

Transmission Generic OBD-II High

What it means

P0711 means the transmission fluid temperature sensor is giving a reading that doesn't make sense — out of range, stuck, or not changing the way the computer expects. The transmission uses fluid temperature to time shifts and torque-converter lockup, so a bad reading typically shows up as harsh or delayed shifting rather than any starting problem. Low or degraded fluid can trigger it, so check that first.

High

Can I keep driving? Usually drivable — the engine starts and runs, but you may get harsh or delayed shifts and no torque-converter lockup; avoid heavy towing until fixed.

How to diagnose & fix

Work through it in order

Check the transmission fluid level and condition first — low or burnt fluid affects the reading.
Scan the live fluid-temperature value and compare it to actual temperature; look for a stuck or out-of-range reading.
Inspect the sensor wiring and connector for damage or corrosion.
Replace the temperature sensor if it tests bad; suspect the control module last. Clear and re-test.
