2000 Toyota Camry Rear Oxygen Sensor


  • 8850

The rear oxygen sensor in your Toyota is responsible for monitoring the operation of your catalytic converter. When your cat fails or there's another issue with your emissions equipment, your secondary or downstream O2 sensor will read high hydrocarbon content in your exhaust stream. Once this happens your Toyota engine computer will trigger and store a OBDII DTC trouble code.

This will turn your Camry check engine light on, and when this happens you'll need a OBDII scan tool to check your stored engine codes. If you have a OBDII trouble code for your secondary or downstream oxygen sensor, you need to test it to make sure that your sensor is the one that's failed and not your cat.

In order to do this, you'll need a DIY article on how to test your rear Camry O2 sensor. Lucky for your our online community at My Pro Street has what you need. Our DIY tutorial will show you how to test the downstream Camry oxygen sensor using just a multimeter.
