High combustion temperatures can lead to increased NOx emissions in the exhaust. To reduce these emissions, the Exhaust Gas Recirculation (EGR) system allows small amounts of exhaust gas into the combustion chamber, lowering the temperature. The EGR valve is the main component of the system, regulating the amount of exhaust gas that enters the intake. It is controlled by a solenoid, which is in turn controlled by the Electronic Control Module (ECM) or Electronic Control Unit (ECU). The solenoid opens and closes to control the vacuum supply to the EGR valve. Common problems with the EGR system include rough idling, stalling, and poor engine performance. To check the EGR valve, inspect it for cracks or leaks and use a vacuum pump to test its operation. If necessary, replace the valve. To check the EGR valve solenoid, verify the vacuum at the solenoid and at the output port. If there are issues with the solenoid or ECU, have them checked by a professional. To replace the EGR valve or EGR tube, disconnect the necessary hoses and bolts, remove the old component, clean the mating surfaces, and install the new component with a new gasket.
