Ford Expedition shift fault sensor causing sudden unintended braking on Ford Expedition

Some Ford Expedition owners report experiencing sudden unintended braking, which may be linked to a faulty shift fault sensor. This issue can stem from an electronic brake control module failure that triggers the OBD C1631 code, leading to unintended brake applications and sudden engagements. Such occurrences are detected by the vehicle's onboard computer and require prompt attention for safety. Owners are advised to have their vehicles inspected by a qualified mechanic if they suspect a shift fault sensor issue to ensure effective diagnosis and resolution.
