What does engine code P0868 mean?
Transmission Fluid Pressure Low
OBD-II Code P0868 is defined as a Transmission Fluid Pressure Low. The Transmission Fluid Pressure Sensor tells the Transmission Control Module (TCM) the pressure of the fluid going through the transmission.
Where is the transmission fluid pressure sensor?
The pump pressure switch is located on the transmission housing next to the pump. The switch lets the computer know what the pressure is coming from the pump when the engine is running. The servo pressure switch is located on the housing near a band or servo in the transmission.
What does low transmission pressure mean?
