P0878

Transmission Fluid Pressure Sensor/Switch "D" Circuit High

DTC P0878, sometimes indicated as P087800 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the transmission (gearbox) causing transmission fluid pressure sensor/switch "d" circuit high.

A transmission fluid pressure sensor/switch "D" circuit high message may be caused by a defective transmission fluid pressure sensor/switch, a wiring problem, a short to power in the wiring, a short to ground in the wiring, or a defective ECM.
If a defective transmission fluid pressure sensor/switch is causing the problem, the sensor/switch should be replaced.
If a wiring problem is causing the problem, the wiring should be repaired.
If a short to power or short to ground is causing the problem, the short should be repaired.
If a defective ECM is causing the problem, the ECM should be replaced.
