P0710 Code: Transmission Fluid Temp Sensor — Causes & Fix
P0710 means a fault in the transmission fluid temperature (TFT) sensor circuit — used to protect the transmission and adapt shifts.
- Applies to
- All OBD-II vehicles (any make or model)
- Est. repair cost
- $40 – $500
- Time to fix
- 1–4 hours
What it means
Causes include a failed TFT sensor (often inside the pan/valve body), low/dirty fluid, or wiring faults. P0710 is a generic OBD-II code defined in the SAE J2012 standard, so it applies to virtually any 1996-or-newer OBD-II vehicle regardless of make. Fix the underlying fault, then clear the code with an OBD-II scan tool — it will return if the problem isn't resolved.
Symptoms
- Check engine light on
- Harsh shifting or limited shift adaptation
- Possible limp mode
How to fix it
- 1
Check fluid and wiring
1. Check transmission fluid level/condition. 2. Inspect the TFT sensor connector and wiring.
- 2
Replace the sensor
1. Replace the TFT sensor (usually in the pan/valve body), then clear the code.
Frequently asked questions
Why is my transmission shifting harshly with P0710?
Without a valid fluid-temperature reading the transmission can't adapt its shift pressures correctly, leading to harsh shifts. Fix the sensor to restore normal shifting.
