C0560 code meaning
Brake Pressure Sensor A Missing Calibration
Chassis system Generic code C05xx codes Check engine light
What C0560 means
The brake module expects stored calibration data for pressure sensor A, normally the master cylinder pressure sensor: zero offset, sensor identity and a flag that the end-of-line or service calibration succeeded. C0560 means this data is absent or does not match the fitted sensor. GM's 2019 and 2025 tables check only the stored status, 500 ms after wake-up, Type A with MIL; GM's 2016 hybrid tables also call it when a test pulse reads above 110 % or below 90 %. Ford hybrids set it when checksum or sensor ID stored in sensor and module disagree (150 or 70 ms). Mitsubishi has a similar uncalibrated sensor code without SAE number (C105E-92). It typically follows a module or hydraulic unit swap; the scan tool calibration usually clears it.
C0560 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.3 to 1 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0560
- ABS, traction or stability lamp on after brake repair
- Brake assist or stability functions unavailable
- Check-engine lamp on some GM models
Common causes of C0560
- Most likelyPressure sensor calibration skipped after replacing the brake module or hydraulic unit
- PossibleCalibration interrupted, e.g. pedal touched or voltage dropped during the routine
- PossibleUsed or wrong hydraulic unit whose sensor data do not match the module
- Less likelyNon-volatile memory error in the brake module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0560 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 C0560
What does C0560 mean?
C0560 means "Brake Pressure Sensor A Missing Calibration". The brake module expects stored calibration data for pressure sensor A, normally the master cylinder pressure sensor: zero offset, sensor identity and a flag that the end-of-line or service calibration succeeded. It is a generic code, so it means the same on every make.
Is it safe to drive with C0560?
Drive gently and only to a workshop. With C0560 the car can go into limp mode (reduced power) to protect itself.
Will C0560 fail an emissions test?
C0560 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0560 to fix?
Difficulty: medium. A typical repair takes 0.3 to 1 hours of work. This is a job for a workshop.
Will C0560 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
