(1) Clean all mating surfaces.

(2) Inspect rubber silicone seal on intake manifold.

Replace seal if damaged.

(3) Install new gasket between the EGR tube and

EGR valve and loose install bolts to EGR valve (Fig.

(4) Slide clamp into the intake manifold slot (Fig.

1). Tighten the bolt to 11.3 N·m (100 in. lbs.).

(5) Tighten bolts to EGR valve to 11.3 N·m (100 in.

lbs.) torque.

(6) Install the air cleaner box.

(7) Connect the negative battery cable.

The EGR valve consists of three major components.

First there is the pintle, valve seat, and housing

which contains and regulates the gas flow. Second

there is the armature, return spring, and solenoid

coil to provide the operating force to regulate the

flow by changing the pintle position. The solenoid coil

assembly is in parallel with a diode and connects to

the two connectors in the connector assembly. The

third major component which senses pintle position

and is connected to the three connectors in the elec-

trical connector.

The exhaust gas recirculation flow is determined

by the engine controller. For a given set of conditions,

the engine controller knows the ideal exhaust gas

recirculation flow to optimize NOx and fuel economy

as a function of the pintle position. Pintle position is

obtained from the position sensor. The engine con-

troller adjusts the duty cycle of 128 Hz power sup-

plied to the solenoid coil to obtain the correct
