P090DClutch B Actuator Control Circuit High
- 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 high state, i.e. a motor or control line is shorted to battery voltage. Ford documents P090D as the short-to-power check of the clutch B motor in the DPS6 PowerShift transmission of the Fiesta and Focus. Ford customer satisfaction program 20B23, covering some 2016-2017 Focus cars, names P090D together with P0900 and several hall and driver codes as signs of failed clutch actuator motors, with erratic shifting, vibration and a lit check engine light; dealers replaced both motors. P090A and P090C are the open and ground faults of the same circuit, P0903 the clutch A equivalent. CARB requires circuit checks on such transmission outputs.
