P0713: Transmission Fluid Temperature Sensor "A" Circuit High
P0713 means Transmission Fluid Temperature Sensor "A" Circuit High. The transmission fluid temperature sensor helps the transmission control module adjust shift timing and torque converter lock-up. The signal voltage is higher than the maximum the module expects. Typical causes are an open ground circuit, a signal wire shorted to voltage, an unplugged connector, or a failed sensor.
Can I keep driving? Drivable with care. Diagnose soon: performance, economy or other components can be affected.
Common symptoms
- Check engine light on
- Harsh, delayed or erratic shifts
- Limp mode
- Possibly incorrect gear display or speedometer issues
Possible causes
- Failed sensor
- Wiring or connector fault (check the transmission connector for fluid)
- Low or contaminated transmission fluid
- Misadjusted range sensor or shift linkage (range sensor codes)
How to diagnose P0713
- Check fluid level and condition.
- Inspect the transmission connector and wiring.
- Check the sensor signal on a scan tool.
- For range sensor codes, check the gear display matches the selector in each position.
What the code means, digit by digit
Generic codes have the same definition on every OBD-II vehicle (petrol cars from model year 1996 in the US, 2001 in the EU; diesels later). Manufacturers can add their own enhanced codes; those are not listed here.
