P0872 SATURN DescriptionThe 4th clutch pressure switch is located in the hydraulic passage to the 4th clutch. When oil pressure is supplied to the 4th clutch, the switch is grounded, LOW. When oil pressure is not supplied, the switch is open, HI. The PCM receives the signal from the 4th clutch pressure switch to detect the fluid pressure status, in order to reduce the shift shock when shifting into 4th gear, from 3rd to 4th or 5th to 4th. If the 4th clutch pressure switch is ON when the gear ratio is not 4th gear, the PCM determines it is a fault and Diagnostic Trouble Code (DTC) P0872 sets. DTC P0872 is a type C DTC. The Diagnostic Trouble Code (DTC) will set if the 4th clutch pressure switch is OFF when the transmission is in 5th gear for 2 seconds or greater.
