P0712 Code - Transmission Fluid Temperature Sensor 'A' Circuit Low Input
Quick Answer
The P0712 diagnostic trouble code (DTC) indicates that there is a low input signal from the transmission fluid temperature sensor 'A' circuit. Common causes include Faulty Sensor: The most common cause of the P0712 code is a faulty transmission fluid temperature sensor, Wiring Issues: Corrosion, damage, or poor connections in the wiring harness can disrupt the signal from the sensor to the ECM, Sensor Placement: If the sensor is incorrectly installed or positioned, it may not accurately measure the temperature of the transmission fluid. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0712 Description
The P0712 diagnostic trouble code (DTC) indicates that there is a low input signal from the transmission fluid temperature sensor 'A' circuit. This sensor is responsible for monitoring the temperature of the transmission fluid, which is crucial for ensuring optimal performance and longevity of the transmission system. When the sensor detects that the transmission fluid temperature is lower than expected, it triggers the P0712 code.
Common Causes of P0712
- Faulty Sensor: The most common cause of the P0712 code is a faulty transmission fluid temperature sensor.
- Wiring Issues: Corrosion, damage, or poor connections in the wiring harness can disrupt the signal from the sensor to the ECM.
- Sensor Placement: If the sensor is incorrectly installed or positioned, it may not accurately measure the temperature of the transmission fluid.
- ECM Malfunction: A malfunctioning engine control module (ECM) can also cause incorrect readings from the sensor.
- Low Transmission Fluid Level: Insufficient transmission fluid can affect the sensor's ability to accurately measure the temperature.
Symptoms of P0712
- Check Engine Light: The most common symptom associated with the P0712 code is the illumination of the check engine light on the dashboard.
- Erratic Shifting: The vehicle may experience erratic shifting or hesitation during gear changes due to incorrect temperature readings.
- Transmission Overheating: In some cases, the transmission may overheat due to the lack of accurate temperature monitoring.
- Reduced Fuel Efficiency: A malfunctioning transmission fluid temperature sensor can lead to decreased fuel efficiency as the transmission may not operate optimally.
- Transmission Slipping: There may be instances of transmission slipping, where the gears do not engage properly, leading to a loss of power and acceleration.
How to Fix P0712
- Diagnostic Scan: Begin by using a diagnostic scan tool to retrieve the fault code and verify the issue with the transmission fluid temperature sensor 'A' circuit.
- Sensor Replacement: If the sensor is found to be faulty, replace it with a new one following the manufacturer's guidelines.
- Check Wiring: Inspect the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace any damaged wires as needed.
- Resetting the Code: After completing the repair, clear the fault code from the ECM memory using the diagnostic scan tool.
- Test Drive: Take the vehicle for a test drive to ensure that the transmission is operating smoothly and that the check engine light does not reappear.
Cost to Fix P0712
The cost of repairing the P0712 code can vary depending on the make and model of the vehicle, as well as the specific cause of the issue. In general, the price range for parts such as a new transmission fluid temperature sensor can be around $50 to $200, while labor costs typically range from $100 to $300. Overall, the total repair cost for addressing the P0712 code may fall in the range of $150 to $500. It's important to note that these estimates are approximate and can vary based on factors such as location, shop rates, and additional repairs that may be required. It's advisable to consult with a qualified mechanic or auto repair shop to get a more accurate cost estimate for your specific situation.
