What C0572 means
C0572 marks the upper end of the same sensor C channel: the pressure signal is at or above its top limit. GM's 2016–2019 hybrid brake modules check the signal voltage against the supply voltage and set the code when the two are practically equal for 0.1 s. The 2019 EBCM uses more than 95.24 % of supply voltage and explicitly includes an open signal line, so GM has no separate open-circuit code for this sensor. In the 2023 and 2025 tables the SENT master cylinder sensor reporting its maximum of 30,000 kPa for 0.96 s triggers it. All variants are Type A with MIL. A short to the reference voltage is the usual wiring cause; since the module would otherwise see heavy braking that is not happening, it stops trusting the sensor and limits brake functions.
C0572 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0572
- Check engine light plus ABS or stability lamp (GM)
- Scan tool shows high brake pressure with the pedal released
- Brake assist and regenerative braking restricted
Common causes of C0572
- Most likelySignal line shorted to the 5 V reference or another supply
- PossibleOpen signal line pulled high by the module input (GM counts this here)
- PossiblePressure sensor reporting full scale because of an internal fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0572 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 C0572
What does C0572 mean?
C0572 means "Brake Pressure Sensor C Circuit High". C0572 marks the upper end of the same sensor C channel: the pressure signal is at or above its top limit. It is a generic code, so it means the same on every make.
Is it safe to drive with C0572?
Drive gently and only to a workshop. With C0572 the car can go into limp mode (reduced power) to protect itself.
Will C0572 fail an emissions test?
C0572 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 C0572 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will C0572 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
