Code P0712 Subaru Description
The P0712 code for Subaru vehicles indicates a low input signal from the transmission fluid temperature sensor. This sensor is responsible for monitoring the temperature of the transmission fluid, which is crucial for ensuring proper operation of the transmission system. When the sensor detects a lower than expected temperature reading, it triggers the P0712 code.
Common Causes of P0712 Subaru
- Faulty Transmission Fluid Temperature Sensor: The sensor itself may be malfunctioning or providing incorrect temperature readings.
- Wiring or Connector Issues: Damaged or corroded wiring or connectors leading to the sensor can cause a low input signal.
- Transmission Control Module Malfunction: A malfunctioning transmission control module can also trigger the P0712 code.
- Low Transmission Fluid Level: Insufficient transmission fluid can affect the sensor's readings and trigger the code.
- Internal Transmission Issues: Internal transmission problems, such as a clogged filter or a failing pump, can also contribute to the P0712 code.
Symptoms of P0712 Subaru
- Check Engine Light: The most common symptom associated with the P0712 code is the illumination of the check engine light on the vehicle's dashboard.
- Erratic Shifting: The transmission may exhibit erratic shifting behavior, such as harsh shifts or delayed engagement.
- Poor Fuel Efficiency: A faulty transmission fluid temperature sensor can cause the vehicle to experience decreased fuel efficiency.
- Transmission Overheating: In severe cases, the transmission may overheat due to inaccurate temperature readings from the sensor.
How to Fix P0712 Subaru
- Diagnose the Issue: Use a scan tool to retrieve the P0712 code and perform a thorough inspection of the transmission fluid temperature sensor, wiring, and connectors.
- Replace the Transmission Fluid Temperature Sensor: If the sensor is found to be faulty, replace it with a new, OEM-quality sensor.
- Check Wiring and Connectors: Inspect the wiring harness and connectors for any damage or corrosion, and repair or replace as necessary.
- Clear the Code: Once the repair is completed, clear the P0712 code from the vehicle's computer using a scan tool.
- Test Drive: Take the vehicle for a test drive to ensure that the transmission is operating correctly and that the check engine light does not reappear.
Cost to Fix P0712 Subaru
The cost estimate for resolving the P0712 code on a Subaru vehicle can vary depending on the specific cause of the issue and the labor rates in your area. In general, replacing the transmission fluid temperature sensor can cost between $100 and $200, including parts and labor. However, additional costs may arise if wiring or connectors need to be repaired or if other components within the transmission system require attention.
