2.14 Heated Oxygen Sensor

To avoid the possibility of personal injury,
allow the exhaust pipe to cool to ambient
temperature (less than 50 °
°°
°
C) before
attempting to remove the oxygen sensor.
Service Precautions
• Handle the HO2S carefully. Do not drop it, and keep it free of grease, dirt and other contaminants. Do not use
cleaning solvents of any type on the HO2S.
• Do not repair the HO2S or any of its parts. Replace the HO2S if any damage is evident.
• The HO2S may be difficult to remove when the engine is cold. Excessive force may damage the threads in the
exhaust manifold or exhaust pipe.

NOTE
Take care the spring (3) does not become
dislodged as the boot is removed.
To aid removal of the boot, use a blunt
instrument to lift the boot edge away from the
coil insulator and spray a release agent between
the boot and the coil insulator.
2 Remove the spring from the ignition coil insulator.
Figure 6C1-3 – 51
Reassemble
1 Position the spring (3) in the insulator recess, refer to Figure 6C1-3 – 51.
