Install referring to the following if the installation positions cannot
be identified.
*: Air fuel ratio sensor 1 is the same for both bank 1 and
bank 2.
CAUTION:

Before installing a new air fuel ratio sensor 1 and heated
oxygen sensor 2, clean exhaust system threads using oxygen sensor thread cleaner (commercial
service tool: J-43897-18 or J43897-12) and apply anti-seize lubricant (commercial service tool).

Do not over torque air fuel ratio sensor 1 and heated oxygen sensor 2. Doing so may cause dam-
age to air fuel ratio sensor 1 and heated oxygen sensor 2, resulting in the “MIL” coming on.Glass tube color
