P0879

DTC P0879, sometimes indicated as P087900 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 intermittent.

This code is set when the PCM detects an intermittent signal from the transmission fluid pressure sensor or switch.
Possible causes of this code include a bad transmission fluid pressure sensor or switch, a wiring issue, or a PCM issue.
If this code is stored, inspect the transmission fluid pressure sensor or switch for damage, and check the wiring for any damage or corrosion. If no damage is found, replace the PCM.
