- How the car detects it
- P2872 is set when clutch A stays closed although it should be open. Mitsubishi's 2023 Outlander PHEV uses it for the engine clutch in the front transaxle: in EV mode, or in series mode where an open clutch would leave a large speed gap, the front motor turns at 750 rpm or more, yet input and output of the clutch differ by 8 rpm or less for 3.5 s. Both the hybrid warning and the MIL come on. In the workshop the front wheels are lifted and turned by hand; if the crankshaft pulley rotates with them, the transaxle is replaced, and a failed pressure test leads to a new valve body. Ford also lists P2872 as an MIL code. A clutch stuck closed drags the engine along, can stall it at a stop and loads the driveline.
