EGR Valve: Description and Operation
LINEAR EGR VALVE SYSTEM
Output messages are sent to the EGR system indicating the proper amount of exhaust gas recirculation necessary to lower combustion temperatures. This
electronic metering of exhaust gas is ten times faster than a vacuum operated system and has improved diagnostic capabilities.
Solenoid Resistance
Positioned at the top of the linear EGR assembly are five terminals:
^
"A" is the pulse width modulated negative signal from the PCM.
^
"E" is the positive voltage from the ignition.
^
"B," "C" and "D" are terminals from the PCM for the integral pintle position sensor.
