How to Replace Oxygen Sensors in a Chevy Metro

The Chevrolet Metro was manufactured from 1998 to 2001. The car is equipped with two oxygen sensors, which are upstream and downstream of the catalytic converter. A failed oxygen sensor increases the amount of fuel burned by the cars engine, decreasing your gas mileage and costing you substantially more at the pump. Save the needless expense by replacing the sensors as soon as you discover the problem.

Instructions

1

Start the engine of the Metro. Let the car idle until the engine reaches operating temperature. When the temperature gauge reaches the point where it commonly runs, turn the engine off.

2

Raise the car with a jack. Position jack stands under the car. Remove the jack when the car is supported on the stands. Locate the sensors on either side of the catalytic converter.

3

Disconnect the electrical connection by pulling it apart. Remove the sensor with a wrench. Install the new oxygen sensor by hand. Tighten it with a wrench. Push the wiring harness connection back together until it clicks.

4

Repeat the process on the second sensor if needed. Raise the car slightly to remove the jack stands. Lower it to the ground.
