What it means
This code has no standardized generic meaning in the SAE/ISO list. Its meaning, if used by your vehicle, depends on the manufacturer.
How it works
The title refers to brake pressure sensor C, but C0573 has no standardized generic definition that confirms what the module detected. Its meaning, including whether it indicates an open circuit, depends on the vehicle manufacturer and brake-system design.
Common causes
Most likely first.
- Manufacturer-specific code definition
- Vehicle-specific diagnostic data needed
Symptoms
- Symptoms depend on the vehicle-specific fault
How to diagnose it
- Use a scan tool that can read the vehicle’s brake module to retrieve the full manufacturer-specific description for C0573.
- Confirm from vehicle-specific service information whether sensor C is fitted and what an open-circuit diagnosis requires.
- Inspect the identified sensor C connector and harness for disconnection, corrosion, broken conductors, or other visible damage.
- Test sensor C circuit continuity and sensor operation only according to the manufacturer’s procedure.
Common fixes
- Reconnect a loose sensor C connector if the vehicle-specific diagnosis confirms it is disconnected.
- Repair an open conductor or damaged connector identified in the sensor C circuit.
- Replace pressure sensor C only if vehicle-specific testing confirms it has failed.
Can I keep driving?
The generic code does not establish whether braking functions are affected. Check the vehicle-specific brake-module description promptly, and do not drive if a brake warning appears or braking feels abnormal.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
