How to Replace the O2 Sensor in a 1997 RAV
When the oxygen sensors in your 1997 RAV4 fail, you will find yourself paying significantly more at the fuel pumps until you replace it. The sensor regulates the engines fuel consumption based on the oxygen density of the exhaust. For the most cost-effective repair method, purchase replacement oxygen sensors from an auto-parts store. Change them at home for the cost of parts, saving the labor expense of a service center.

Raise the RAV4 with a jack and insert a set of jack stands beneath the truck. Remove the jack when the jack stands are secure.
2Pull the electrical connection apart to disconnect it from the top of the sensor. The sensors are threaded into the exhaust system on either side of the catalytic converter.
3Remove the sensor with a ratchet equipped with an oxygen sensor socket. Install the new sensor by hand to avoid cross threading, which can damage the sensor and the mounting area. Press the electrical connection into place.
4Repeat the process for the second sensor if needed. Raise the car with a jack to remove the jack stands. Return the RAV4 to the ground.
