What it means
Brake Pedal Position Sensor A 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 A reports pedal movement to the control module, which uses that signal to coordinate braking and stability functions. C0619 sets when the learned offset for sensor A falls outside the module's allowed learning range, often because the sensor or pedal linkage is mispositioned or its calibration was not completed.
Common causes
Most likely first.
- Brake pedal position sensor A 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 sensor or calibration codes and review freeze-frame data for pedal position readings.
- With the vehicle stationary, inspect sensor A at the brake pedal for looseness, incorrect seating, damaged mounting, or interference from the pedal mechanism.
- Watch sensor A data while slowly pressing and releasing the pedal, checking for a stable resting value and smooth change.
- Inspect sensor A wiring and connector terminals for damage, poor pin fit, corrosion, or an intermittent connection.
- If the installation and circuit are sound, perform the manufacturer's sensor offset learning or calibration procedure and confirm the code does not return.
Common fixes
- Correct sensor A alignment or installation at the brake pedal.
- Repair a loose, damaged, or corroded sensor A connector or wiring.
- Complete the specified brake pedal sensor learning procedure.
- Replace sensor A or repair worn pedal mechanism parts if its reading remains out of range.
Can I keep driving?
The vehicle may still brake normally, but ABS or stability control and possibly brake assist can be reduced. Drive cautiously and have the sensor offset checked promptly; do not rely on stability assistance.
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.
