(888) 312-8812 Login SignupThe Paccar Exhaust Gas Recirculation (EGR) Pressure Differential Sensor monitors pressure changes within the EGR system during engine operation. As exhaust gas flow varies, the sensor detects differences across the system and converts that information into an electrical signal. This signal is sent to engine controls to adjust EGR operation in response to changing conditions. The sensor functions continuously while the engine is running and reacts automatically without driver involvement. It remains part of the emissions control system and supports regulated exhaust management. The Paccar 2003641 contributes to accurate EGR system feedback during daily vehicle operation.
