EGR Transducer
Electric EGR Transducer (EET)
PURPOSE
The Electric Exhaust Gas Recirculation Transducer combines the functions of the Back Pressure Transducer and the Electric Vacuum Solenoid
into one devise.
TRANSDUCER OPERATION
The backpressure transducer measures the amount of exhaust gas backpressure on the exhaust side of the EGR valve and it varies the amount of
vacuum supplied to the EGR valve. The transducer uses this backpressure signal to supply the correct amount of vacuum to the EGR valve
depending on engine load conditions. Vacuum is supplied to the backpressure transducer from a port on the EVAP Purge Solenoid.
SOLENOID OPERATION
The Electric Vacuum Solenoid is controlled by the Powertrain Control Module (PCM). The PCM monitors engine coolant temperature and other
operating conditions to determine when to energize the solenoid. When the PCM supplies a ground to the solenoid (energizing), vacuum is cut off
from the EGR transducer. When the PCM removes the ground from the solenoid (de-energizing), vacuum is allowed to flow through the solenoid
and out to the EGR transducer.
