OXYGEN SENSOR

GENERAL
See Figure 4-14. The oxygen sensor (O2 Sensor), located in
the rear header pipe, monitors oxygen content in the exhaust
gas and converts it to a voltage reading. This voltage reading
is used by the ECM to maintain the proper air/fuel ratio during
closed loop operation.

INSTALLATION

NOTES
Do not install sensors that have been dropped or impacted

may have occurred. Replacement sensor assemblies have
threads coated with anti-seize lubricant and new seal rings.
If reinstalling O2 sensor, apply a thin coat of anti-seize
(Part No. 98960-97) to threads of each O2 sensor prior to
installing in header. Do not use any other grease or sealant
product on sensor threads. The electrical connector must
also be clean and free of any dielectric grease.
