This exhaust pressure sensor from DELPHI is designed to accurately measure the pressure within the exhaust system. Proper measurement of exhaust gas pressure is crucial for the engine control unit (ECU) to optimize fuel injection, ignition timing, and exhaust gas recirculation (EGR) operation. This leads to improved engine performance, better fuel efficiency, and reduced emissions. Engineered to meet or exceed OE specifications, this sensor ensures reliable and consistent readings for your vehicle's exhaust system.
