P0714
Transmission Fluid Temperature Sensor A Circuit Intermittent
Automatic transmission
Generic OBD-II
High
What it means
P0714 means the transmission control module saw an intermittent signal from fluid temperature sensor A. The module uses fluid temperature to time shifts and lock the torque converter, so a signal that cuts in and out can cause erratic or harsh shifting and may push the transmission into a protective failsafe mode.
High
Can I keep driving? Driveable, but shifting may be erratic or harsh when the fault acts up, and the transmission may drop into a failsafe mode; get it diagnosed before long trips.
Common symptoms
What you'll notice
- Check-engine light on

How to diagnose & fix
Work through it in order
- Scan and read freeze-frame data to capture the conditions when it sets.
- Wiggle-test the sensor wiring and connector while watching the temperature reading for dropouts.
- Measure the sensor's resistance and compare it to the temperature-vs-resistance spec.
- Check the transmission fluid level and condition.
- Replace the sensor if faulty, clear the code, and road-test to confirm.
FAQ
Quick answers
Is it safe to drive with P0714?+
Short term yes, but shifting can be harsh or erratic and the transmission may enter failsafe. Because it's intermittent, get it diagnosed before it worsens.
Can I just clear P0714?+
It will return the next time the intermittent fault appears until the wiring or sensor is repaired.
