Laymans terms

This code means that the car's computer has detected a problem with the sensor that measures how hard the transmission fluid is pushing in a specific part of the transmission. It's like when a video game controller button isn't working right.

Explanation

The P0875 code is triggered when the Powertrain Control Module (PCM) detects an issue with the transmission fluid pressure sensor or switch circuit labeled 'D'. This sensor helps monitor the pressure of the fluid in the transmission to ensure proper operation.

Technical description

The transmission fluid pressure sensor/switch is responsible for sending signals to the PCM about the pressure of the transmission fluid. If the PCM receives a signal that is out of the expected range or no signal at all from the 'D' circuit, it sets the P0875 code. This can affect the transmission's ability to shift gears properly.

Symptoms

• Check Engine Light is on

• Transmission slipping

• Harsh or erratic shifting

Common Causes

• Faulty transmission fluid pressure sensor

• Damaged or corroded wiring/connectors

• Faulty PCM
