How to Remove the Oxygen Sensor on a Tracker

A Tracker is a small sport utility vehicle that was sold under the GEO and Chevrolet nameplates from 1989 to 2004. The Chevrolet Equinox took the Trackers place in the 2005 model year. The oxygen sensor on your Tracker makes sure the correct air/fuel ratio is achieved by sending signals to the engines electronic computer module. Your engine will not run at its maximum efficiency if the oxygen sensor is not operating properly. The first step in replacing the oxygen sensor in your Tracker is to remove the old one.

Set the parking brake. If the engine has been run recently, let it cool for a few hours before you begin.

2

Raise the vehicle with a hydraulic jack and place jack stands under your Trackers frame to support its weight. Lower the hydraulic jack and set it aside.

3

Crawl under the vehicle on the right hand side (drivers side) near the drivers door. Locate the catalytic converter, which is mounted in-line with the exhaust pipe.

4

Locate the oxygen sensor which is mounted in the exhaust pipe near the rear of the catalytic converter.

5

Remove the wiring harness connector from the oxygen sensor by squeezing in the connector tabs with your fingers while simultaneously pulling the connector from the sensor.

6

Remove the sensor from the exhaust pipe by turning it out with an adjustable wrench in a counterclockwise direction.
