 O2 SENSOR

 REMOVAL
 Disconnect the O2 sensor connector.
 Remove the bolts attaching the muffler and
 dismantle the muffler.
 Apply        anti-seize  compound       on
 circumference of thread area before
 installation.
 Torque: 2.5 kgf-m (25 N-m, 18 lbf-ft)

 Don't twist the wire when removing the               O2 sensor
   connector.


 INSPECTION

 Measure the resistance between each White
 wire terminals of the O2 sensor side
 connector.
 Standard: 6.7  ~ 9.5 




 Measure the input voltage for the O2 sensor.
 Disconnect the O2 sensor's connector.
 The positive terminal connects the pin of
 harness wire and the negative terminal
 connects the earth. The figure should be
