Laymans terms

This code means that the motor that helps pump fluid in the car's transmission isn't working right. It's like when a toy car's motor doesn't have enough power to make it go.

Explanation

The P287D code indicates that the torque output of the electric or auxiliary transmission fluid pump motor is not within the expected range. This could affect the transmission's ability to shift gears properly.

Technical description

The electric or auxiliary transmission fluid pump is responsible for maintaining the necessary fluid pressure in the transmission system, especially in hybrid or electric vehicles. The P287D code is triggered when the torque output from this pump's motor is detected to be outside the manufacturer's specified range, indicating a potential issue with the motor or its control system.

Symptoms

• Transmission warning light on

• Erratic or harsh shifting

• Transmission overheating

Common Causes

• Faulty electric transmission fluid pump motor

• Issues with the pump motor control circuit

• Mechanical failure within the transmission

Glossary

Torque: A measure of the force that can cause an object to rotate about an axis.

Transmission: A system in a vehicle that transmits power from the engine to the wheels.

Diagnosis steps

• Check for other related codes

• Inspect the wiring and connectors to the pump motor

• Test the pump motor's electrical circuit for proper voltage and ground

Repair procedures

• Replace the faulty transmission fluid pump motor

• Repair or replace damaged wiring or connectors

• Reprogram or replace the transmission control module if necessary

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools

Estimated repair cost

$300 - $800
