Step 1 (When indicating C44/P0135:)
1) Remove the right frame cover. (VL800K1 7-2)
2) Turn the ignition switch OFF.
3) Check the HO2 sensor coupler for loose or poor contacts.
4) Insert the needle pointed probes to the HO2 sensor coupler.
5) Turn the ignition switch ON and measure the heater voltage
between W/B wire (ECM side) and ground.
6) If the tester voltage indicates the battery voltage for few sec-
onds, it is good condition.
! Heater voltage: Battery voltage (W/B – Ground)
NOTE:
Battery voltage can be detected only during few seconds after
ignition switch is turned ON.
" 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
& Tester knob indication: Voltage (')
Is the voltage OK?
YES Go to Step 2 (When indicating C44/P0135:).
• Loose or poor contacts on the ECM coupler.
