Clutch A Actuator Control Circuit Low
What it means
P0902 means the control circuit for clutch "A" actuator reads an abnormally low voltage — this is on an automated-manual or dual-clutch gearbox where a motor or solenoid, not a pedal, works the clutch. The engine still starts, but if the actuator can't be driven properly the clutch may not engage or release cleanly, making the car shift roughly or struggle to move. It's usually a wiring or actuator fault worth diagnosing before drivability worsens.
Can I keep driving? The engine starts, but on an automated-manual or dual-clutch transmission the clutch may not engage or disengage properly — shifting can be rough and the car may struggle to move; get it checked promptly.
Common symptoms
What you'll notice
- Check-engine light on
- Difficulty shifting gears
- Clutch slips or fails to engage/disengage cleanly
- Jerky launches or the car struggles to move
Common causes
Most likely first
- Open or short to ground in the clutch actuator control wiring (reads low)Likely
- Corroded or loose connector at the clutch actuatorCommon
- Failed clutch actuatorCommon
- Failed control module (TCM/ECM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the clutch actuator connector and wiring for damage, corrosion, or shorts to ground.
- Measure the actuator's resistance and control voltage against service data.
- Replace the clutch actuator if it fails its electrical checks.
- If wiring and actuator are good, suspect the control module. Clear and re-test.
P0902 by make
Based on commonly reported failure patterns across owner and repair communities, not on our scan data.
Dodge
On Dodge vehicles with the dual-clutch automatic, such as some Dart models, clutch actuator faults can cause shuddering or hesitation. Get it checked soon.
Ford
Commonly reported on Ford vehicles with the PowerShift dual-clutch automatic, such as some Focus and Fiesta models. Shuddering, hesitation or loss of drive with this code is worth getting checked soon.
Hyundai
On Hyundai models with the dual-clutch automatic, clutch actuator faults can cause hesitation or shuddering. Get it checked soon.
Volkswagen
On VW and Audi models with the DSG dual-clutch gearbox, clutch actuator faults can show up as shuddering or hesitation. Get it checked soon, since the cause may be in the mechatronic unit.
