EGR Differential Pressure Sensor: Testing and Inspection

Inspection 

1. Apply vacuum to the EGR differential pressure sensor using a vacuum pump.
2. Turn the ignition switch to ON.
3. With the EGR differential pressure sensor connector still connected, measure the voltage at EGR differential pressure sensor connector pin 3

(GRY).
