sor 2 on both banks using heated oxygen sensor wrench [SST].
? Put marks to identify installation positions of each heated oxy-
gen sensor 2.
CAUTION:
? Be careful not to damage heated oxygen sensor 2.
? Discard any heated oxygen sensor 2 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; replace with a new
sensor.
