REMOVAL
CAUTION:
•
Wear protective gloves when removing the sensor.
•
The exhaust pipe assembly is extremely hot
immediately after the engine has stopped.
•
Confirm that the exhaust pipe assembly has cooled
down before removing it.

REMOVE AIR FUEL RATIO SENSOR
(a) Remove the 3 bolts, then remove the No. 2 exhaust
manifold stay. (for LH Bank)
(b) Disconnect the 2 air fuel ratio sensor connectors.
(c) Using SST, remove the 2 air fuel ratio sensors from
the exhaust manifold.

REMOVE AIR FUEL RATIO SENSOR
(a) Check the resistance.
(1) Using an ohmmeter, measure the resistance
between the terminals.
Standard resistance
If the result is not as specified, replace the air
fuel ratio sensor.
