4.6L Exhaust Gas Recirculation (EGR) System Module
WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not remove any part of the engine emission control system. Operating the engine without the engine emission control system will reduce fuel economy and engine ventilation. This will weaken engine performance and shorten engine life.
The EGR system returns a portion of the exhaust gas to the intake manifold to reduce the combustion temperature. This results in lower nitrous oxide formation.
The PCM controls the EGR system module. When the EGR system module valve opens, exhaust gas flows to the intake manifold.
The EGR system module to exhaust manifold tube:
- connects the exhaust manifold to the EGR valve.
The EGR system module transducer:
- monitors the EGR system module flow rate through the EGR to exhaust manifold tube.
- sends an EGR system module flow rate signal to the PCM.
The EGR vacuum regulator solenoid uses input from the PCM to change the EGR system module operation.
