P28C7Clutch A Motor Phase U-V-W Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P28C7 flags that the clutch A motor's phases are electrically intact but the motor does not respond as expected, e.g. currents and rotation do not match the commanded drive. Stellantis documents it in bulletin 21-040-26 (May 2026) for European 2022-2025 Jeep Renegade and Compass with the 1.5 MHEV engine and the 7HDT300 hybrid dual-clutch gearbox: together with P2787 it points to the actuator cylinder of the odd-gear clutch, which in this gearbox is clutch A. Cause given there is small debris in the transmission blocking a pump inside the actuator; the MIL comes on and odd gears may be lost. If the guided test fails, the actuator is replaced (1.5 labour hours). The even-gear counterpart is P28D5 with P27F3.
- What you may notice
- MIL and transmission warning lamp on
- Odd gears unavailable on the 7HDT300
- Often stored together with clutch A temperature code P2787
- Likely causes
- LikelyDebris from the transmission jamming the pump in the clutch A actuator (Stellantis 7HDT300)
- PossibleWorn or sluggish clutch A actuator motor
- RareIncreased resistance in a phase connection causing unbalanced currents
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
