- How the car detects it
- P2871 means clutch A does not close, or slips so much that it behaves as if open. Mitsubishi documents this for the clutch in the front transaxle of the 2023 Outlander PHEV, which links the engine to the wheels in parallel mode: once parallel mode has been active for 2 s, the PHEV-ECU counts how often the speeds before and after the clutch differ by 75 rpm or more for 2 s, and after eight such events the code sets and the MIL lights. Mitsubishi points to a worn clutch, low fluid, a leaking or contaminated valve body, the oil pump, pressure regulator or relief valve, and very low ambient temperature. Volvo also stores P287100 in the rear-axle inverter of its T8 hybrids and clears it with IEM software.
