identified.
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.

a. Remove quick connector cap from quick connector.
b. Disconnect quick connector from fuel tube as follows:
CAUTION:
Disconnect quick connector by using the quick connector release [SST: — (J-45488)], not by pick-
ing out retainer tabs.
i. With the sleeve side of quick connector release facing to quick connector, install the quick connector
release onto fuel tube.
ii. Insert the quick connector release (A) into quick connector (2)
until sleeve (B) contacts and goes no further. Hold quick connec-
tor release on that position.
CAUTION:
Inserting quick connector release hard will not disconnect
quick connector. Hold quick connector release where it
contacts and goes no further.
iii. Draw and pull out quick connector straight from fuel tube (1).
CAUTION:
 Pull quick connector (E) holding position (D) as shown in
the figure.
 Never pull with lateral force applied. O-ring inside quick connector may be damaged.

 Avoid fire and sparks.
 Keep parts away from heat source. Especially, be careful when welding is performed around
them.
 Never expose parts to battery electrolyte or other acids.
