P0714 Code: Transmission Fluid Temperature Sensor A Circuit Intermittent
🟠 Moderate severity · drivable
You can drive, but the temperature reading can cut out at any time, so shifting may become unpredictable.
What P0714 means
The transmission fluid temperature sensor signal is cutting in and out. Intermittent faults are usually caused by a loose or corroded connection, or a sensor that is starting to fail. The computer loses its temperature reading off and on, which can make shifting unpredictable.
Symptoms
- Check engine light is on
- Intermittent harsh or delayed shifts
- Transmission occasionally goes into fail-safe mode
- Shifting behavior changes without warning
Common causes
- most common: Loose or corroded connector
- common: Faulty transmission fluid temperature sensor
- common: Damaged or chafed wiring
- less common: Intermittent ground connection
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Clean and re-seat the sensor connector | Yes | $10–30 |
| Inspect and repair damaged wiring | Mechanic | $80–250 |
| Replace the transmission fluid temperature sensor | Mechanic | $150–400 |
Frequently asked questions
Can I drive with a P0714 code?
Yes, but the temperature signal can drop out without warning, making shifts unpredictable. Drive cautiously and get it diagnosed soon.
Why is the P0714 code intermittent?
Intermittent codes usually come from loose or corroded connections or a sensor that is failing slowly. The fault appears and disappears as the connection makes and breaks.
How much does it cost to fix a P0714?
Cleaning a connector is nearly free and often fixes it. If the sensor needs replacing, expect $150–$400 including parts and labor.
