Daytona IROC V6-181 3.0L SOHC VIN 3 FI (1992)
EGR Control Valve: Description and Operation
California Emissions
EET Solenoid Operation
EGR System Vacuum Connections
Electric EGR Transducer (EET)
Note: The EET assembly is a vacuum control solenoid and a backpressure transducer, in one package.
Purpose
The PCM controls when the EGR valve can be actuated, through the solenoid portion of the EET.
OPERATION
^
When the PCM energizes (grounds), the solenoid, vacuum does not reach the transducer.
^
Vacuum reaches the backpressure transducer when the solenoid is de-energized
^
The solenoid will always be energized (no EGR), under following conditions:
-
Engine warm-up, (engine coolant temperature below 40 °F)
-
Engine at idle
-
Wide Open Throttle (WOT) operation
-
Rapid acceleration/deceleration
-
During EGR system diagnostic check
Note: If the wiring or connector is disconnected from the solenoid, the EGR valve will operate at all times, (adversely affecting engine idle and
performance).
