The Exhaust Back Pressure (EBP) sensor monitors exhaust gas pressure within the emissions system and provides critical feedback to the engine control module (ECM). This information is used to manage EGR operation, turbocharger performance, and Diesel Particulate Filter (DPF) regeneration. A failing sensor can result in improper DPF regeneration, reduced engine performance, poor fuel economy, and Check Engine Light illumination.
