2. Inspect the pre - catalytic oxygen sensor heater resistance value
A. Turn the ignition switch to position "LOCK".
B. Disconnect the pre - catalytic oxygen sensor wiring
harness connector E05.
C. Measure the resistance of the heater that between
terminal 2 and terminal 4 of pre - catalytic oxygen
sensor wiring harness connector E05.
Standard Resistance Value: 20 ℃ (68ºF) 1 ~ 6 Ω
Is the resistance value normal?
Y
Go to step 3.
N
Replace the pre - catalytic oxygen sensor.
Refer to: Pre - Catalytic Oxygen Sensor
(3.1.13 Electronic Control System - ME7,
Removal and Installation).
3. Inspect the heater working voltage
