Transmission Fluid Pressure Sensor/Switch D Circuit
The P0875 code means the vehicle's onboard diagnostic system has detected: Transmission Fluid Pressure Sensor/Switch D Circuit. This is a moderate severity code.
- Keep driving?
- Short distances only
- DIY difficulty
- hard
- Estimated cost
- $150 - $600 (parts and labor)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.
Basic scanners only read engine codes. This reads transmission, ABS, and airbag too.

What Are the Symptoms of P0875?
- Check Engine Light illuminated
- Erratic shifting in certain gear ranges
- Transmission slip or flare during specific shifts
- Possible limp mode activation
What Causes P0875? (Most Likely First)
- Faulty transmission fluid pressure sensor D Very High
- Wiring fault in pressure sensor D circuit High
- Corroded or damaged connector at sensor D Moderate
- Internal valve body passage blockage at sensor D tap Low
Can I Still Drive with P0875?
Short distances only. P0875 is rated moderate severity. Keep trips short and get it diagnosed soon rather than waiting for symptoms to worsen.
Frequently Asked Questions
Why does my transmission have four pressure sensors?
Advanced transmissions with 9 or 10 speeds use multiple pressure sensors for precise control of different clutch packs and hydraulic circuits. Sensor D monitors a fourth pressure point.
Is sensor D more critical than sensors A, B, or C?
Each sensor monitors a different circuit and all are important for proper shift control. The severity depends on which clutch pack or circuit sensor D monitors in your specific transmission.
Is P0875 diagnosed the same way as other pressure sensor codes?
Yes, the diagnostic process is the same: check fluid level, monitor sensor data, inspect wiring, and test the sensor if needed.
