C0575: Park Brake Actuator Position Signal Malfunction
The EPB module has detected an out-of-range position signal from a caliper actuator. The module cannot determine whether the brake is fully applied or released.
What C0575 means
C0575 is a generic OBD-II chassis code in the ABS & brakes group.
- Check engine light
- Usually off
- Emissions-related
- No
- Limp mode possible

Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
Common causes
- 01Actuator position sensor failedMost likely
- 02Actuator mechanically jammed (corrosion)Possible
Can I drive with C0575?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Usually lights the ABS, traction or stability warning instead of the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose C0575
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just C0575. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Fix other faults first
If other codes are stored, start with power-supply, sensor-circuit and communication codes. They can cause this code as a side effect.
- 3
Check live data
Watch the related sensor and actuator readings in live data (EPB actuator, EPB module, Actuator wiring) and compare them with expected values in the service information for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Actuator position sensor failed; actuator mechanically jammed (corrosion). Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

C0575 FAQ
What does C0575 mean?
C0575 means “Park Brake Actuator Position Signal Malfunction”. The EPB module has detected an out-of-range position signal from a caliper actuator. The module cannot determine whether the brake is fully applied or released.
Is C0575 serious? Can I keep driving?
We rate C0575 as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes C0575?
The most common causes, from most to least likely: Actuator position sensor failed; Actuator mechanically jammed (corrosion). Test before replacing parts, because several causes can set the same code.
How much does it cost to fix C0575?
Typical labor is about $100–$315 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix C0575 myself?
DIY difficulty is moderate. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will C0575 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
