Inspection
Inspect the louvered end of the sensor for grease,
dirt, excessive carbon build up or othe
r
contamination.
A special anti-seize compound is used on the O2
sensor threads. This compound consists of glass
breads suspended in a liquid graphite solution.
The graphite burns away with engine heat, but the
glass breads will remain, marking the senso
r
easier to remove.
New or service sensors will already have the
compound applied to the threads. If a sensor is
removed and is to be reinstalled for any reason,
the threads must have anti-seize compound
applied.
Installation Procedure
1. Install the O2 sensor to the exhaust pipe.
Apply anti-seize compound or the equivalent to the
threads of the oxygen sensor, if necessary.
2. Tighten the O2 sensor with specified tightening
torque.
Tightening Torque
Bolt: 42N
m (4.3kgf
m)
3. Connect a sensor connector to the O2 sensor.
4. Connect the negative battery cable.
NOTE:
Verify any DTCs (diagnosis Trouble Code) are not
stored after replacement.
Verify no exhaust gas leaking from the senso
r
threads after replacement.

valve.
4. Loosen a bolt and remove the purge solenoid from
the intake manifold.
Installation Procedure
1. Put on the purge solenoid on the intake manifold.
2. Tighten the purge solenoid by a bolt.
3. Connect a connector to the purge solenoid.
4. Connect two hoses to the purge solenoid valve.
5. Connect the negative battery cable.
NOTE:
Verify any DTCs (diagnosis Trouble Code) are not
stored after replacement.
Verify proper connection of two hoses.

Service Precaution
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE
SRS COMPONENTS OR THE SRS WIRING, REFE
R
TO THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY, OR OTHERWISE UNNEEDED SRS SYSTEM
REPAIRS.
CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, o
r
other corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener.
When you install fasteners, use the correct
tightening sequence and specifications. Following
these instructions can help you avoid damage to
parts and systems.
