P090C on Ford: Causes, Symptoms and Fix Cost
Quick Answer
Not safe to drive
P090C on a Ford means the transmission control module found a low voltage in the control circuit of clutch actuator B. It is a generic code, and it is most often seen on dual-clutch and other semi-automatic gearboxes, where an electric actuator opens and closes each clutch. A technician forum report ties it to the Ford 6-speed DPS6 PowerShift. The code points at the actuator's circuit: the actuator, its wiring and connector, a poor ground or the control module.

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Ford models that log P090C.
Ford Focus (6DCT250 DPS6 dry-clutch automatic)
2012-2018
A technician forum post describes a 2016 Focus SE 2.0 with the 6-speed DPS6 dual-clutch gearbox that stored P090C, described there as clutch B actuator control circuit low. The shop's troubleshooting found no wiring fault, the control module and actuator motor were replaced, and the car came back with the same symptoms but no code, so confirm the cause before buying parts. The dry-clutch DPS6 uses electric motor and solenoid actuation.

Ford Fiesta (6DCT250 DPS6 dry-clutch automatic)
2011-2017
The Fiesta shares the 6DCT250 DPS6 dry-clutch gearbox with the Focus, so the same checks apply. The PowerShift's known problems include faulty connector pins and a poorly connected main ground at the control module, and failing shifter motors, so check connectors and ground before replacing an actuator.

How to diagnose P090C on a Ford with OBD2
- Read all stored codes and the freeze frame. Other P09xx clutch codes, speed sensor codes or U-codes for lost communication change the picture.
- Check the 12V battery and charging voltage first. Low supply voltage can set actuator circuit faults and costs little to rule out.
- Inspect the connector at the actuator and at the control module for corrosion, bent or pushed-back pins and moisture, then check the main ground connection at the module.
- Test the actuator circuit against the workshop wiring diagram: supply, ground and signal continuity, with the plugs disconnected.
- Use manufacturer-level software to read the actuator and clutch data and run the gearbox's own tests. A generic OBD2 reader shows the code and freeze frame but cannot read clutch position or actuator duty on most cars.
- After any actuator, clutch or module replacement, the gearbox usually needs an adaptation or relearn with manufacturer software. Ask whether it is included in the quote.
- Confirm the diagnosis before ordering parts. In one forum report of a 2016 Focus, the module and actuator motor were replaced after troubleshooting found no wiring fault, and the car came back with the same symptoms but no code.
