How Do I Replace an O2 Sensor on a 95 Chevy Corsica

The 1995 Chevrolet Corsica depends on an oxygen sensor within the exhaust system to monitor the amount of oxygen in the exhaust. The oxygen content of the exhaust determines how much fuel the car uses to keep the engine running. If the sensor fails, your car may start to use a lot more fuel than needed. To save this needless fuel expense, buy a replacement sensor from an auto-parts store and change it at home. The location of the O2 sensor will vary, depending on the engine in your Corsica.

Instructions

1

Start the engine and allow it to warm up, heating up the exhaust system. Turn the engine off before removing the sensor. Raise the Corsica with a jack. Place a set of jack stands beneath the car to support it.

2

Locate the oxygen sensor from beneath the car. The sensor threads into the rear of the manifold or the side of the exhaust pipe. Pull the wiring harness connector apart on the end of the sensor.

3

Remove the oxygen sensor from the Corsica with an oxygen sensor socket and ratchet. Place the new sensor into the mounting area and thread it by hand until it no longer turns easily. Tighten it with an oxygen sensor socket and ratchet.

4

Torque the sensor to 30 foot-pounds with your torque wrench. Connect the wiring harness by pressing the connectors together.

5

Raise the car with a jack to remove the jack stands. Return the car to the ground.
