O2/O2 HT SENSOR
REMOVAL/INSTALLATION
Disconnect the O2/O2 HT sensor connector,
then remove it from exhaust muffler.
Installation is in the reverse order of removal.
Tighten the O2/O2 HT sensor to specified
torque.
Torque: 2.5 kgf-m (25 N-m, 18 lbf-ft)
O2 sensor data should be outputted only
when its temperature over 350°C.
O2 heater heat O2 sensor to over 350°C
earlier than exhaust muffler.
The data of O2 sensor is one of the data that
control fuel injector operation.
INSPECTION
(Using a commercially available
multimeter)
Disconnect the O2/O2 HT sensor connector.
Measure the resistance between each White
wire terminals of the O2/O2 HT sensor side
connector.
Standard: 7.7±1.2 " (at 20°C/68°F)
