Code P1E31 Description
The diagnostic trouble code P1E31 indicates that there is a high voltage condition detected in the circuit of the auxiliary transmission fluid pump phase W current sensor. The auxiliary transmission fluid pump is responsible for maintaining proper fluid pressure in the transmission system, which is crucial for smooth gear shifts and overall transmission performance. The current sensor is designed to monitor the electrical current flowing through the pump to ensure it is operating within specified parameters.
Common Causes of P1E31
- Faulty auxiliary transmission fluid pump
- Malfunctioning current sensor
- Corroded or damaged wiring in the circuit
- Electrical issues such as a short circuit or high resistance in the circuit
- Software or programming issues in the transmission control module
Symptoms of P1E31
- Erratic shifting or delayed gear engagement
- Transmission slipping or jerking
- Illumination of the check engine light
- Reduced fuel efficiency
- Transmission overheating
How to Fix P1E31
- Diagnose the issue by using a scan tool to retrieve the specific fault code and perform a visual inspection of the wiring and components in the circuit.
- Test the auxiliary transmission fluid pump and current sensor to determine if they are functioning properly.
- Replace the faulty auxiliary transmission fluid pump or current sensor as needed.
- Repair or replace any damaged wiring in the circuit.
- Clear the fault code from the vehicle's computer and perform a test drive to ensure the issue has been resolved.
Cost to Fix P1E31
The cost of repairing a P1E31 code can vary depending on the specific cause of the issue and the labor rates in your area. Typically, the cost of replacing the auxiliary transmission fluid pump or current sensor can range from $200 to $500, including parts and labor. Additional costs may apply if there are other underlying issues that need to be addressed. It's recommended to consult with a professional mechanic to get an accurate estimate based on your vehicle's make and model.
