What C053D means
The brake pressure sensor A signal is electrically present, but its value does not fit the braking situation. GM stores C053D in the brake system control module, calling it a circuit performance fault: on 2019 Silverado/Sierra 1500 drivers got a hard pedal plus the Service Brake Assist warning (PIT5638), and bulletin 20-NA-073 lists it among faults that drop the brake-by-wire system into its mechanical Push-Thru mode; the fix is BSCM software. Stellantis logs it as Brake Pressure Sensor 1 Performance in the PCM of the 2023 Grand Cherokee, where the PCM compares the sensor with the pedal position sensor inside the BSCM; remedy is a PCM flash or an ABS initialization. Mitsubishi maps C106C-02 to it (Outlander PHEV 2023, ASC lamp plus MIL after two trips).
C053D at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyHard
- Typical labor0.3 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of C053D
- Brake assist or stability control warning shown
- Brake pedal hard or travelling further than usual
- Check-engine lamp on some models
Common causes of C053D
- Most likelyBrake or engine control software with an over-sensitive plausibility check (several bulletins)
- PossiblePressure and pedal sensors not initialized after module or hydraulic unit replacement
- PossibleAir in the brake lines distorting the pressure build-up
- Less likelyStop-light switch or pedal sensor delivering a mismatching reference
- Less likelyDrifting pressure sensor in the hydraulic unit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C053D 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 C053D
What does C053D mean?
C053D means "Brake Pressure Sensor A Range/Performance". The brake pressure sensor A signal is electrically present, but its value does not fit the braking situation. It is a generic code, so it means the same on every make.
Is it safe to drive with C053D?
Drive gently and only to a workshop. With C053D the car can go into limp mode (reduced power) to protect itself.
Will C053D fail an emissions test?
C053D 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 C053D to fix?
Difficulty: hard. A typical repair takes 0.3 to 3 hours of work. This is a job for a workshop.
Will C053D clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
