Use special care when servicing an oxygen sensor or air/fuel ratio sensor:
A) Oxygen sensors and air/fuel ratio sensors have a permanently attached pigtail and electrical connector which cannot be removed from the sensor. Damage or removal of the pigtail or electrical connector will ruin the sensor. Do not attempt to repair the oxygen sensor lead. If the lead is damaged, the sensor will need to be replaced.
B) Grease, dirt and other contaminants should be kept away from the electrical connector and the louvered end of the sensor.
C) Do not use cleaning solvents of any kind on an oxygen sensor or air/fuel ratio sensor.
D) Do not drop or roughly handle an oxygen sensor or air/fuel ratio sensor.
E) Be sure to install the silicone boot in the correct position to prevent the boot from melting and to allow the sensor to operate properly.
