EGR Control Solenoid: Description and Operation
EGR Solenoid Location:
To regulate exhaust gas flow, an
PCM controlled EGR control valve
relay solenoid is used in the vacuum line. The PCM uses information from the following sensors to regulate the solenoid:
^

^
Throttle Position (TP) sensor.
The
EGR vacuum control has a vacuum
solenoid that the
PCM turns "ON" or "OFF."
