What P2872 means
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.

Symptoms of P2872
- Engine turns with the wheels in EV mode, unusual noise or drag
- Engine stalls when the vehicle stops
- Hybrid system warning and MIL
Common causes of P2872
- Most likelyClutch A plates seized or welded together
- PossibleForeign material holding the proportional valve in the apply position
- Less likelyControl unit commanding or reading clutch state incorrectly
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |

What to do next
- Note P2872 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2872
What does P2872 mean?
P2872 means "Clutch A Stuck Engaged". P2872 is set when clutch A stays closed although it should be open. It is a generic code, so it means the same on every make.
Is it safe to drive with P2872?
Drive gently and only to a workshop. With P2872 the car can go into limp mode (reduced power) to protect itself.
Will P2872 fail an emissions test?
Yes, it can. P2872 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2872 to fix?
Difficulty: workshop only. A typical repair takes 1 to 10 hours of work. This is a job for a workshop.
Will P2872 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
