Can you change your own 02 sensor?
I changed my downstream sensor by driving the car, 2000 Alero, onto ramps then I set the emergency break. I disconnected the battery to reset the computer before I removed the sensor. The sensor on this car was located on a short pipe between the converter and the muffler. I guess that there is a special socket to remove the sensor but I just grabbed the nut of the sensor with a pipe wrench, since I was replacing the sensor anyway. With the extra pulling power of the big wrench the sensor screwed right off. I carefully pulled the cable of the sensor away from the clips all the way up to the connector. The connector had a safety clip which pulled out, then the electrical connector is pulled apart by bending down the plastic side clip of the bottom connector. I replaced the new sensor using care not to break the wires. Then I worked backwards replacing the cable the same way that I removed the old one.
What do colors mean on 02 Sensor need to connect universal 02 sensor and don't know which colors to match you need to connect Universal 02 sensor to Toyota wiring?
From Underneath the vehicle locate the sensor and using an open end box wrench lossen and remove the o2 sensor follow the wire up into the engine compartment dissconnect from the connection, plug in the new 02 sensor and carefully fish it through so that you can install it as the old one was removed
