Today, we’re going to show you how to replace the rear O2 sensor, also known as the downstream sensor, in a truck. This sensor is located on the driver’s side, right behind the catalytic converters.

To begin, you’ll need a 22-millimeter wrench. With the wrench, you can easily disconnect the O2 sensor by pushing up to loosen it. Follow the wire up to the top of the transfer case to locate the connector, push the little tab down, and pull on the connector to disconnect it. After that, you can spin the O2 sensor out of the exhaust system.

When installing the new O2 sensor, remember to put the sensor in first and tighten it before plugging it in. This will prevent any damage to the wires. Use the 22-millimeter wrench to tighten up the O2 sensor from the front just like when you loosened it. Once it’s tight, feed the wire up over the transfer case and connect it into the wire harness.

Thank you for watching. For quality auto parts, fast and free shipping, and the best customer service, visit us at 1AAuto.com.
