EGR System
The EGR system reduces oxides of nitrogen (NOx) emissions by recirculating exhaust gas into the intake manifold and combustion chambers. The system consists of the EGR valve, EGR vacuum control valve, EGR position sensor, and EGR control solenoid valve.
EGR Valve Lift Sensor
PCM calculates ideal EGR valve lifts for varying operating conditions. EGR valve lift sensor detects amount of EGR valve lift and sends the information to PCM. PCM compares this information (actual EGR valve lift) with ideal EGR valve lift. If the 2 signals differ, PCM closes EGR control solenoid valve to reduce vacuum applied to the EGR valve.
