CAUTION:
 Before installing a new air fuel ratio sensor and a new heated
oxygen sensor, 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).
 Never over torque air fuel ratio sensor 1 and heated oxygen sensor 2. Doing so may cause damage
to air fuel ratio sensor and heated oxygen sensor, resulting in “MI” coming on.
