EGR System Schematic
PURPOSE
Sensor detects EGR control valve operation. Signals PCME to optimize EGR system operation through its control of the EGR vent and vacuum
side solenoid valves.
LOCATION
Top of EGR valve.
OPERATION
Sensor is a variable resistor. PCME detects resistance changes as EGR control valve moves during operation.
