When an O2 sensor (too called an Oxygen sensor) is malfunctioning on a Motor lorry, the engine management unit isn't getting the Correct info it needs to flight the engine; as a decision, the motorcar may flow poorly. Repeat this process for any other O2 sensors that you want to remove.
Lift up the vehicle using the jack and place it on jack stands. Make sure the vehicle is secure before you crawl underneath it.
2. Crawl underneath the truck and find the oxygen sensors. These are little metal tubes that stick out perpendicular to the exhaust tubing, typically near the catalytic converters. They also have two wires coming out of the ends, making it the only thing with wiring leading into the exhaust. Unplug the wiring to the O2 sensor using your hands.
3. Place the O2 sensor socket on the 3/8-inch ratchet and put the socket on the sensor so that the wiring is running out of the slot in the socket body. Unbolt the sensor and place it to the side. The place is to alternate the sensor, and it's a quota easier to end than one might consider. This duty should catch approximately 30 minutes to create, depending on the year, dash off and number of O2 sensors on the truck.
