Code P1E1C Description
The diagnostic trouble code P1E1C refers to an issue with the Auxiliary Transmission Fluid Pump Control Module Hybrid Battery Voltage Isolation Sensor Circuit 1 operating at a low voltage. In hybrid vehicles, the auxiliary transmission fluid pump helps to maintain proper transmission fluid pressure for smooth operation. The hybrid battery voltage isolation sensor is responsible for monitoring the voltage levels within the hybrid battery system to ensure proper functioning. When this sensor detects low voltage in the circuit, it can indicate a potential problem with the transmission fluid pump control module, which can lead to issues with transmission performance and overall vehicle operation.
Common Causes of P1E1C
- Faulty auxiliary transmission fluid pump control module
- Defective hybrid battery voltage isolation sensor
- Wiring or connection issues in the sensor circuit
- Low battery voltage or electrical system issues
- Software or programming issues in the transmission control module
Symptoms of P1E1C
- Erratic shifting or hesitation during gear changes
- Transmission slipping or jerking
- Reduced power and acceleration
- Illumination of the check engine light
- Vehicle going into limp mode
How to Fix P1E1C
- Diagnose the exact cause of the low voltage condition using a diagnostic scanner
- Inspect the auxiliary transmission fluid pump control module and sensor for any signs of damage or malfunction
- Check the wiring and connections in the sensor circuit for any loose or damaged components
- Replace the faulty transmission fluid pump control module or sensor if necessary
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved
