EGR Differential Pressure Sensor (7/320) [2019-2022]: Description

The EGR differential pressure sensor is used to determine the amount of low pressure exhaust gas recirculation that can be applied. The sensor measures the pressure difference between the exhaust system and the air intake system, before the low pressure turbocharger. The sensor transmits the measured value as a digital signal and is monitored by the Engine Control Module (ECM).
