The oxygen sensor is installed in the exhaust manifold and is removed in the same manner as a spark plug. Always remove electrical connection before trying to remove the sensor. Exercise care when handling the sensor do not drop or handle the sensor roughly; the electrical connector and louvered end must be kept free of grease and dirt. If a anti-seize compound is used in installation, make sure to coat just the threads of the sensor and care should be used not to get compound on the sensor itself. You should disconnect the negative battery cable when servicing the oxygen sensor.
