5. Inspect the pre - catalytic oxygen sensor ground circuit
A. Turn the ignition switch to position "LOCK".
B. Disconnect the pre - catalytic oxygen sensor wiring
harness connector E05.
C. Disconnect the engine control module wiring
harness connector E01.
D. Measure the resistance between terminal 3 of pre -
catalytic oxygen sensor E05 and terminal 36 of
engine control module wiring harness connector
E01.
Standard Resistance Value: less than 5 Ω
Is the resistance value normal?
Y
Go to step 6.
N
Repair the circuit between the pre - catalytic oxygen
sensor wiring harness connector E05 terminal 3 and
the ECM wiring harness connector E01 terminal 36.
6. Inspect the pre - catalytic oxygen sensor
A. Exchange the pre - catalytic oxygen sensor with the
normal vehicle of the same model
B. Use a diagnostic tool access to engine data stream,
observe the "pre - catalytic oxygen sensor voltage"
parameter.
Standard Voltage Value: 0.1 ~ 0.9 V
Is the fault eliminated?
Y
Replace the failed pre - catalytic oxygen sensor.
N
Go to step 7.
