OBD-II Error Code P0712: How to Fix Transmission Fluid Temperature Sensor Low Circuit

Q: Can I drive with error code P0712?

It's not recommended. Driving with a low TFT sensor circuit can cause transmission to shift improperly, overheat, or suffer damage. Have it diagnosed and repaired as soon as possible.

Q: What does P0712 mean?

P0712 means the Transmission Fluid Temperature (TFT) sensor circuit is reading a voltage lower than normal, indicating a short to ground, faulty sensor, or wiring issue.

Q: How much does it cost to fix P0712?

If you DIY, the sensor costs $20-$50 and tools are cheap. Professional repair costs $150-$400, including diagnosis and labor.

Q: Will clearing the code make it go away?

Clearing the code may temporarily turn off the check engine light, but if the underlying issue isn't fixed, the code will return.

Q: Can a faulty TFT sensor cause transmission damage?

Yes. If the sensor reads incorrectly, the transmission may not shift properly, leading to overheating and premature wear.

Abstract

Error code P0712 indicates that the transmission fluid temperature (TFT) sensor is reporting a voltage below the normal operating range, which can cause transmission shifting problems and reduced fuel economy. This guide will help you diagnose and repair the issue safely.
