What it means
This code identifies a fault associated with extended brake pedal travel information sent to the PCM. The specific failure depends on the diagnostic subtype.
At a glance
- Usually lights the ABS or stability-control warning light
How it works
The PCM receives information about unusually long brake-pedal travel, generally from the brake or ABS control system. This subfault code flags a problem with that extended-travel information; the subtype is needed to tell whether the pedal travel itself or its reported signal is at fault.
Common causes
Most likely first.
- Extended brake pedal travel
- Fault in the monitored signal or circuit
Symptoms
- Brake warning light
- Brake pedal may travel farther than usual
How to diagnose it
- Read the C0075 subtype and freeze-frame data with a scan tool, and check for related brake or ABS codes that identify the source.
- With the vehicle safely parked, check brake-fluid level and look for visible leaks or other signs of a brake-system problem.
- Check whether the pedal feels unusually low or travels farther than normal, without driving the vehicle to test it.
- Inspect the wiring and connectors involved in reporting brake-pedal travel for damage, looseness, or corrosion.
- Use scan-tool live data and the vehicle wiring information to check whether the reported travel changes plausibly as the pedal is pressed, then test the identified circuit to the manufacturer's specification.
Common fixes
- Repair a brake-fluid leak or other confirmed cause of excessive pedal travel.
- Restore the correct fluid level after fixing any leak, following the vehicle's service procedure.
- Repair damaged wiring or clean and secure a loose or corroded connector in the travel-information circuit.
- Replace a faulty travel-sensing component or control module only after circuit checks confirm the failure.
Can I keep driving?
If the pedal travels farther than usual, feels soft, or braking is reduced, do not drive; arrange a tow because braking ability may worsen. If braking feels normal, have the code checked promptly and avoid high-speed or unnecessary trips until the brake warning is understood.
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.
