Code P1E3A Description

The P1E3A diagnostic trouble code (DTC) relates to the Auxiliary Transmission Fluid Pump Motor Torque Delivered Performance. This code indicates an issue with the performance of the auxiliary transmission fluid pump motor in delivering torque as expected. The auxiliary transmission fluid pump plays a crucial role in ensuring proper lubrication and cooling of the transmission components. When the motor's torque delivery is not up to par, it can lead to inadequate transmission fluid circulation, which can result in overheating, increased friction, and accelerated wear and tear on the transmission components.
