1 Connect the diagnosis instrument, the ignition
switch is in the "ON" Next step
yes Next step 2 Dial the joint oxygen sensor wire harness, check
with a multimeter, the joint 1# (connected with the
oxygen sensor white relative) is about 12V value
between I voltage at pin
No To step 4
yes Next step 3 Using a multimeter to check the oxygen sensor 1
(white), 2#(white) resistance between Pin value at 2

in 5.4~6.6 ohm
No Replace the sensor
No Replace the fuse 4 15A fuse check the main relay power lines of the
fuse
yes Next step
No Repair or replace the wire
harness 5 Check the ECU X1-8#, the main relay X1_21#
pins respectively in sensor connector 1# (and
oxygen sensor connector, relative to white) 2#
(with the oxygen sensor is connected between pins
relative color line) to supply short circuit)
