P0876: Transmission Fluid Pressure Sensor/Switch D Circuit Range/Performance
What to do
Ask for the pressure sensors to be compared with one another rather than assessed individually.
What this code means
The fourth pressure reading is valid but does not match expectation. As with the other pressure sensors, its value lies in comparison — agreement across sensors points at a shared cause, disagreement locates the loss in this circuit.
Likely causes
Start here
- Worn valve body · specialist
- Low or degraded transmission fluid · easy
- Faulty pressure control solenoid · moderate
Less common
- Worn clutch packs · specialist
- Faulty transmission fluid pressure sensor · moderate

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
