Code P1E2D GMC Description
The P1E2D diagnostic trouble code (DTC) for GMC vehicles refers to the Auxiliary Transmission Fluid Pump Phase V Current Sensor Circuit Low Voltage. This code indicates that there is a problem with the current sensor circuit associated with the auxiliary transmission fluid pump in the vehicle. The auxiliary transmission fluid pump plays a crucial role in ensuring proper lubrication and cooling of the transmission system. When the current sensor circuit detects low voltage, it means that there may be an issue with the power supply or the sensor itself, which can lead to inadequate fluid circulation and potential damage to the transmission components.
Common Causes of P1E2D GMC
- Faulty auxiliary transmission fluid pump.
- Malfunctioning current sensor.
- Wiring issues or loose connections in the sensor circuit.
- Low voltage in the power supply to the pump.
- ECM software or hardware issues.
Symptoms of P1E2D GMC
- Illumination of the check engine light on the dashboard.
- Transmission slipping or delayed shifting.
- Overheating of the transmission fluid.
- Reduced fuel efficiency.
- Unusual noises coming from the transmission system.
How to Fix P1E2D GMC
- Diagnose the root cause of the issue by using a scan tool to retrieve the DTC and perform a thorough inspection of the auxiliary transmission fluid pump, current sensor, wiring, and power supply.
- Replace the faulty auxiliary transmission fluid pump or current sensor if they are found to be defective.
- Repair any damaged or corroded wiring in the sensor circuit and ensure all connections are secure.
- Test the power supply voltage to the pump and address any issues with low voltage.
- Clear the DTC from the ECM memory and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P1E2D GMC
The typical repair costs for addressing the P1E2D code can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, replacing the auxiliary transmission fluid pump or current sensor can range from $200 to $500, including parts and labor. However, additional costs may apply if there are wiring or power supply issues that require attention. It's advisable to consult with a qualified mechanic or auto repair shop to get an accurate estimate based on the specific circumstances of your vehicle. Keep in mind that labor rates can vary, so it's recommended to inquire about local rates before proceeding with the repairs.
