P090CClutch B Actuator Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Set when the control circuit of the clutch B actuator shows a low state, which on the documented application means a short to ground. Ford defines P090C as the short-to-ground check of the clutch B motor in the DPS6 PowerShift gearbox, paired with P090A for an open circuit and P090D for a short to power. Ford's TCM program 14M02 for 2011-2015 Fiesta and Focus also lists P090C among the codes that a defective TCM can cause, so the module belongs on the suspect list along with the motor and its wiring. Swapping the identical clutch motors helps: if the fault moves to P0902, the motor is bad. CARB requires circuit monitoring of such outputs. Expect missing gears, erratic shifts or no drive.
