Removal and Installation
 
 
REMOVAL
  • Disconnect each joint and mounting.
  • Remove heated oxygen sensor 2 with following procedure.
    • Using heated oxygen sensor wrench [SST: KV10114400] (A), removal heated oxygen sensor 2 .
      : Exhaust front tube
      : Vehicle front
      cautionDiscard any 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; use a new one.
 
 
INSTALLATION
Note the following, and install in the reverse order of removal.
caution
  • Always replace gaskets with new ones when reassembling.
  • Discard any heated oxygen sensor 2 which has been dropped onto a hard surface such as a concrete floor. Use a new one.
  • Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxygen sensor thread cleaner [commercial service tool (J-43897-18 or J-43897-12)] and apply anti-seize lubricant (commercial service tool).
  • Never over torque heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sensor 2, resulting in the “MIL” coming on.
  • If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat insulator, remove them.
  • When installing heat insulator avoid large gaps or interference between heat insulator and each exhaust pipe.
  • Remove deposits from the sealing surface of each connection. Connect them securely to avoid gas leakage.
  • Temporarily tighten mounting nuts and bolts. Check each part for unusual interference and mounting rubber interference, and then tighten them to the specified torque.
  • When installing each mounting rubber, avoid twisting or unusual extension in up/down, front/rear and right/left directions.
  • Install the mounting rubber with the FR arrow mark facing the front of the vehicle.
