Fig. 6 EGR valve position sensor:
This sensor, Fig. 6, is used to monitor the EGR valve pintle position. The computer applies a reference voltage to the EVP sensor, and the resulting signal from the EVP sensor is proportional to the amount of exhaust gases flowing through the EGR valve pintle into the intake manifold. Depending on the input from this and other sensors, the computer can increase or decrease EGR flow by activating or deactivating a pair of solenoid vacuum valves.
