Intake Air Temperature (Iat) Sensor - Isuzu 1999 RODEO Workshop Manual

4. Remove the sensor from the exhaust pipe.
f Because of the expansion and contraction of the
metal in the exhaust system over time, this may be
difficult if the engine temperature is below 48°C
(120°F).
Inspection Procedure
All four sensors are identical. Inspect each in the same
way.
1. Inspect the pigtail and the electrical connector for
grease, dirt, corrosion, and bare wires or worn
insulation.
2. Inspect the louvered end of the sensor for grease,
dirt, or other contaminations.

Installation Procedure
IMPORTANT:
f A special anti-seize compound, P/N 5613695, is used
on the HO2S threads. This compound consists of
glass beads suspended in a liquid graphite solution.
The graphite burns away with engine heat, but the
glass beads will remain, making the sensor easier to
remove.
f 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.
1. Apply anti-seize compound or the equivalent to the
threads of the oxygen sensor, if necessary.
2. Install the oxygen sensor on the exhaust pipe in its
original position.
Tighten
f Tighten the oxygen sensor to 55 N·m (40 lb in.).
3. Connect the pigtail to the wiring harness.
4. Connect the negative battery cable.
