Code P1E29 Description
The P1E29 diagnostic trouble code (DTC) refers to the Auxiliary Transmission Fluid Pump Control Module Calculated Motor Position Performance. This code indicates that there is a problem with the control module that manages the auxiliary transmission fluid pump, which is responsible for regulating the flow of transmission fluid in certain vehicles. The control module calculates the motor position to ensure proper operation of the pump, and if it detects that the motor position performance is outside of acceptable parameters, it will trigger this code.
Common Causes of P1E29
- Faulty Auxiliary Transmission Fluid Pump Control Module
- Worn or damaged transmission fluid pump
- Electrical issues such as wiring faults or connector problems
- Mechanical issues with the transmission system
- Software glitches or calibration errors
Symptoms of P1E29
- Erratic shifting or hesitation when changing gears
- Decreased fuel efficiency
- Transmission overheating
- Illumination of the Check Engine Light
- Harsh or delayed transmission engagement
