Code P0712 Ford Description
The P0712 Ford diagnostic trouble code (DTC) indicates that the Transmission Fluid Temperature Sensor 'A' is reporting a low input signal to the vehicle's engine control module (ECM) or transmission control module (TCM). The transmission fluid temperature sensor is a crucial component that measures the temperature of the transmission fluid and sends this information to the vehicle's computer system. This data is essential for the proper operation of the transmission, as it helps regulate fluid viscosity, cooling, and overall performance.
Common Causes of P0712 Ford
- Faulty Sensor: The most common cause of a P0712 DTC is a malfunctioning transmission fluid temperature sensor.
- Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM/TCM can result in a low input signal.
- Faulty ECM/TCM: A malfunctioning engine control module or transmission control module can also trigger this code.
- Low Transmission Fluid Level: Insufficient transmission fluid can affect the sensor's readings, leading to a low input signal.
- Extreme Temperatures: Operating the vehicle in extremely hot or cold conditions can also impact the sensor's performance.
Symptoms of P0712 Ford
- Check Engine Light: The most common symptom associated with a P0712 DTC is the illumination of the check engine light on the vehicle's dashboard.
- Transmission Shifting Issues: The transmission may experience erratic or delayed shifting patterns, leading to a rough driving experience.
- Overheating: The transmission may overheat due to the incorrect fluid temperature readings, potentially causing damage to internal components.
- Reduced Fuel Efficiency: The vehicle may exhibit decreased fuel efficiency as a result of the transmission operating outside of optimal temperature ranges.
How to Fix P0712 Ford
- Diagnostic Scan: Begin by using a diagnostic scanner to retrieve the trouble codes and confirm the presence of a P0712 DTC.
- Inspect Sensor: Check the transmission fluid temperature sensor for any visible damage or signs of malfunction. Replace the sensor if necessary.
- Check Wiring: Inspect the wiring harness connecting the sensor to the ECM/TCM for any damage or corrosion. Repair or replace as needed.
- Verify Fluid Level: Ensure that the transmission fluid level is at the correct level and top up if necessary.
- Clear Codes: After completing the repairs, clear the trouble codes from the vehicle's computer system and test drive to verify that the issue has been resolved.
Cost to Fix P0712 Ford

The over speed light flashing at idle. Drive up to 25 mph goes out. Get to cruise speed flashing again and this is from a cold start. Got codes P0712/P1783 for TFT sensor. Check fluid level at temp/idle and found level at top of crosshatchs 3/4" above full hole in stick. Could this cause the sensor to malfunction and if fluid is drained/ codes erased to see if they flash again? Ford F150/4.2L/4R70W tra
