NOTES

•

Do not install sensors that have been dropped or impacted
by other components. Damage to the sensing element
may have occurred.

•

Replacement sensor assemblies have threads coated with
ANTI-SEIZE LUBRICANT and new seal rings.

•

If O2 sensor will be reused, replace the gasket. Use a
high-quality professional grade side cutter for gasket
removal. Make sure larger side of new gasket faces
exhaust.

•

If O2 sensor will be reused, apply a thin coat of ANTI-
SEIZE LUBRICANT to threads of each oxygen sensor

prior to installing in header. Do not use any other grease
or sealant product on sensor threads.

•

The electrical connector must be clean and free of any
dielectric grease.

Front O2 Sensor

If reusing oxygen sensor:

Remove used seal and install a

new

one.

Apply a light coating of ANTI-SEIZE LUBRICANT to
threads.

FUEL INJECTORS

GENERAL

Do not use solvents or other products that contain chlorine
on plastic fuel system components. Chlorine can degrade
plastic fuel system components, which can cause a loss
of fuel system pressure or engine stalling and could result
in death or serious injury. (000621b)

See the electrical diagnostic manual for information on the
function and testing of the fuel injectors.

REMOVAL

Remove induction module. See

4.11 INDUCTION

MODULE

NOTE

If not replacing fuel supply tube or O-rings, do not remove.

See

Figure 4-30

. Remove fastener (1) retaining fuel supply

tube (2).

Pull fuel supply tube from fuel rail. Remove sealing washer
(4) and O-ring (3) from fuel supply tube. Remove second
O-ring from fuel rail bore. Discard sealing washer and O-
rings.

See

Figure 4-31

. With a rocking motion, pull fuel injectors

with attached fuel rail from the induction module.

See
