Code P1E2A GMC Description
The P1E2A diagnostic trouble code (DTC) for GMC vehicles refers to the Auxiliary Transmission Fluid Pump Phase U Current Sensor Circuit Low Voltage. This code indicates that there is a problem with the current sensor circuit in the auxiliary transmission fluid pump, specifically in phase U. The auxiliary transmission fluid pump plays a crucial role in ensuring proper lubrication and cooling of the transmission system. The current sensor circuit is responsible for monitoring the electrical current flowing through the pump, and a low voltage reading suggests an issue with the sensor or the pump itself.
Common Causes of P1E2A GMC
- Faulty current sensor
- Wiring issues in the sensor circuit
- Defective auxiliary transmission fluid pump
- Low transmission fluid levels
- Electrical system issues
Symptoms of P1E2A GMC
- Harsh shifting
- Transmission slipping
- Reduced fuel efficiency
- Transmission overheating
- Illumination of the Check Engine Light
