P0714: Transmission fluid temperature sensor: circuit intermittent
The gearbox oil temperature sensor signal keeps dropping out, which is typical of a loose connector or a wire making poor contact.

What P0714 means
The transmission fluid temperature sensor tells the control unit how hot the automatic gearbox oil is. It uses that figure to adjust how smooth the shifts are and to decide when to lock the torque converter. This code means the signal comes and goes: sometimes it is correct and sometimes it drops out or jumps.
Most common causes
- Loose gearbox or sensor connector
- Corroded or oily terminals
- Wire broken inside its insulation, making contact on and off with vibration
- Sensor with an intermittent internal fault
- Transmission control unit fault (uncommon)
Symptoms
- Engine or gearbox warning light on
- Harsh or late shifts, especially when cold
- Slightly higher fuel use because the converter does not lock
- Limp mode on some cars
Can you drive with P0714?
With care You can drive, but with a false temperature reading the shifts can be harsh and the gearbox works harder. Have it checked soon and avoid towing or hard driving.

How to check it
If your scanner shows the gearbox oil temperature, watch it live: after the car has stood overnight it should be close to the engine and outside temperature, then rise gradually as you drive. If the value jumps over bumps, look for a poor contact.
How to read and clear P0714 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P0714 with its description and whether it’s confirmed, pending or permanent.
This code is usually stored by the gearbox control unit. If the car reports it over standard OBD, you read it for nothing with FREE; to read it straight from the gearbox control unit, with its description and clearing, you need PRO.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P0714?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P0714 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
