What it means
Brake Pedal Position Sensor B Offset Exceeded Learning Limit: the control module has detected this fault condition.
At a glance
- Usually lights the ABS or stability-control warning light
How it works
Brake pedal position sensor B provides a second pedal-position signal that the control module compares with the other pedal input for braking and stability functions. C061A sets when sensor B's learned offset is beyond the allowed range, which can point to sensor B alignment, wear, wiring, or incomplete calibration.
Common causes
Most likely first.
- Brake pedal position sensor B misaligned or incorrectly installed
- Sensor or pedal mechanism wear
- Damaged wiring or poor connection
- Calibration or learning not completed
Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
How to diagnose it
- Scan the brake and stability modules for related pedal sensor codes and review freeze-frame data for sensor B and other pedal readings.
- Inspect sensor B and its mounting at the brake pedal for incorrect position, looseness, damage, or pedal linkage interference.
- View sensor B live data while slowly pressing and releasing the pedal, checking that its resting value and movement are consistent.
- Inspect sensor B's connector and harness for corrosion, backed-out terminals, damaged insulation, or a poor connection.
- If the sensor and circuit appear sound, carry out the manufacturer's offset learning procedure for sensor B and verify the fault stays cleared.
Common fixes
- Reposition or correctly install brake pedal position sensor B.
- Repair damaged wiring or poor terminal contact at sensor B.
- Run the manufacturer's sensor B calibration or learning procedure.
- Replace sensor B or repair worn pedal mechanism parts if the offset remains outside the learning limit.
Can I keep driving?
Braking may remain available, but ABS or stability control and possibly brake assist may be reduced. Use extra care, avoid situations that depend on stability control, and arrange prompt diagnosis.
