• Solutions

The P0875 fault code indicates an issue with the Transmission Fluid Pressure Sensor/Switch D Circuit, which is responsible for monitoring the hydraulic pressure within the transmission. When this code is triggered, it generally implies that the vehicle's computer has detected an abnormal reading from this sensor.

What are the symptoms of the P0875 code?

Common symptoms associated with the P0875 code include:

• Transmission slipping or delayed engagement.
• Check Engine Light illuminated.
• Erratic shifting behavior.
• Poor acceleration performance.
• Increased engine RPMs without corresponding vehicle speed.

What causes the P0875 code?

Several factors can contribute to the P0875 code, including:

• Faulty transmission fluid pressure sensor.
• Wiring issues such as shorts or open circuits.
• Poor electrical connections.
• Low transmission fluid levels or contaminated fluid.
• Malfunctions in the transmission control module (TCM).

How to fix P0875?

To resolve the P0875 fault code, follow these steps:

1. Inspect the wiring and connectors for any visible damage or corrosion.
2. Check the transmission fluid level and condition; replace or top off if necessary.
3. Test the transmission fluid pressure sensor to determine functionality.
4. If the sensor is faulty, replace it.
5. Clear the fault code and test drive the vehicle to ensure the issue is resolved.
