What P090C means
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.
P090C at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor1 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P090C
- Check engine light on
- Even gears or reverse unavailable
- Limp mode or no drive
Common causes of P090C
- Most likelyClutch B actuator motor with internal short to ground
- PossibleFailed TCM output stage (Ford program 14M02 lists this code)
- PossibleChafed motor wire touching ground
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P090C means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 9 | Area: transmission. |
| 0C | The exact fault in that area. |
What to do next
- Note P090C 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 P090C
What does P090C mean?
P090C means "Clutch B Actuator Control Circuit Low". Set when the control circuit of the clutch B actuator shows a low state, which on the documented application means a short to ground. It is a generic code, so it means the same on every make.
Is it safe to drive with P090C?
Drive gently and only to a workshop. With P090C the car can go into limp mode (reduced power) to protect itself.
Will P090C fail an emissions test?
Yes, it can. P090C 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 P090C to fix?
Difficulty: medium. A typical repair takes 1 to 3 hours of work. This is a job for a workshop.
Will P090C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
