Standard Ignition Blind Spot Detection System Warning Sensor P/N:BSD128
Standard Motor Products
Standard Ignition BSD129 blind spot detection system warning sensor for the 2019-2021 Ford Transit Connect and other vehicles senses traffic in the lanes beside the vehicle. It feeds the blind spot warning system that alerts the driver.
A blind spot warning light that stays on or alerts that never appear can mean the sensor has failed. A damaged wire or a loose plug can look the same from the driver's seat, so with the vehicle off, look over the connector and wiring for damage before you replace the sensor.
It is a direct-fit OE replacement for the 2019-2021 Ford Transit Connect, the 2017-2018 Ford F-250 Super Duty and the 2017-2018 Ford F-350 Super Duty. This listing is one sensor, and the quantity per vehicle is two.
