• Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a concrete floor; install a new one.
• Do not over-tighten the heated oxygen sensor. Doing so may damage the heated oxygen sensor,
resulting in the MIL coming on.
• If any mounting insulator is badly deformed, repair or replace it. If deposits such as mud pile up on
the mounting insulators, clean and inspect them.
• Temporarily tighten the nuts on the exhaust manifold side and the bolts on the vehicle side. Check
each part for interference with other components, and then tighten the nuts and bolts to specifica-
tion.
INSPECTION AFTER INSTALLATION
• With the engine running, check exhaust tube joints for gas leakage and unusual noises.
• Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.
