P0713 Code: Transmission Fluid Temperature Sensor A Circuit High
🟠 Moderate severity · drivable
You can drive, but the transmission may act as if the fluid is overheated and could go into a fail-safe mode.
What P0713 means
The transmission fluid temperature sensor is reading a voltage that is too high, which usually means an open circuit, a bad sensor, or damaged wiring. The computer may act as if the fluid is extremely hot, which can cause it to limit shifting or trigger fail-safe mode.
Symptoms
- Check engine light is on
- Harsh or delayed shifts
- Transmission may go into fail-safe (limp) mode
- Transmission may shift to keep engine RPM low
Common causes
- most common: Faulty transmission fluid temperature sensor
- common: Open wiring or loose connector
- common: Corroded terminals in the connector
- less common: Damaged wiring harness
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Inspect the sensor wiring and connector for opens | Yes | $20–60 |
| Replace the transmission fluid temperature sensor | Mechanic | $150–400 |
| Repair open or damaged wiring | Mechanic | $80–250 |
Frequently asked questions
Can I drive with a P0713 code?
Yes, but the transmission may shift oddly or go into fail-safe mode because the computer thinks the fluid is overheated. Have it checked soon.
What does a high circuit on the temperature sensor mean?
It means the sensor signal voltage is too high, which usually points to an open circuit, a bad sensor, or damaged wiring in the circuit.
How much does it cost to fix a P0713?
A sensor replacement usually costs $150–$400 including parts and labor. Wiring repairs are typically cheaper.
