Figure 18 EGR control
The EGR valve, installed in the top front of the air
intake manifold, has three major components: a two
head valve assembly, a DC motor, and an Integrated
Circuit (IC). The IC has three Hall effect position
sensors that monitor valve movement.
The EGR drive module, mounted on the EGR drive
module mounting bracket above the ECM/IDM
assembly, controls the DC motor.
