Code P1E19 2018 Chevrolet Silverado Description
The P1E19 diagnostic trouble code (DTC) in a 2018 Chevrolet Silverado indicates that the Auxiliary Transmission Fluid Pump Control Module is detecting a low voltage condition within the system. The auxiliary transmission fluid pump is responsible for maintaining proper fluid pressure in the transmission system, especially during low-speed and stop-and-go driving conditions. When the control module detects that the system voltage is below the specified threshold, it triggers the P1E19 code.
Common Causes of P1E19 2018 Chevrolet Silverado
- Faulty auxiliary transmission fluid pump
- Malfunctioning control module
- Wiring or connection issues
- Low battery voltage
- Electrical system issues
Symptoms of P1E19 2018 Chevrolet Silverado
