Brake Pedal Position Sensor A and B Correlation
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
Brake-by-wire and electronic brake systems use two redundant pedal position sensors. Their readings disagree by more than the diagnostic tolerance - one or both has drifted, or wiring picks up noise on one channel.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
