If the vehicle was built with an oxygen sensor, you will need an oxygen sensor.
It's integrated into the oxygen sensor. Buy a new oxygen sensor and you get a free oxygen sensor heater.
Remove the oxygen sensor vacuum to. Remove the oxygen sensor screws. Reverse the process to install the new oxygen sensor.
Remove the vacuum hose from the oxygen sensor. Remove the oxygen sensor retaining screws. Reverse the process to install the new oxygen sensor.
To replace the oxygen sensor disconnect the oxygen sensor electrical connector. Use an oxygen sensor socket to remove the sensor. spray the sensor with penetration oil if it is difficult to loosen. install in reverse.
it is the oxygen sensor afterthe cat conv
No
An Oxygen sensor does not reset. You have to replace them and yes they are expensive.
