Detailed Description

GBR 522-057 is an exhaust backpressure sensor used in diesel electronic control systems. It helps the vehicle’s control module monitor exhaust pressure so the engine can manage operating conditions correctly. When the sensor fails, the vehicle may set a check engine light, run poorly, or produce elevated exhaust emissions. This part is a fitment-based replacement for select Ford E-350 Club Wagon, E-350 Super Duty, E-350 Econoline, E-350 Econoline Club Wagon, Excursion, F-250 HD, F-250 Super Duty, F-350, and F-350 Super Duty diesel models.
