4-90 FI SYSTEM DIAGNOSIS
Is the voltage OK?
• W/G wire or B/Br wire open or shorted to
ground, or poor
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
YES
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
NO Replace the HO2 sensor with a new one.
6) After repairing the trouble, clear the DTC using SDS tool.
( 4-28)
Step 1 (When indicating C44/P0135:)
1) Turn the ignition switch OFF.
2) Remove the left under cowling. ( 8-5)
3) Check the HO2 sensor coupler
If OK, then measure the HO2 sensor resistance.
4) Disconnect the HO2 sensor coupler and measure the resis-
tance between terminals.
HO2 heater resistance: Approx. 8 Ω at 23 °C (73 °F)
NOTE:
* Temperature of the sensor affects resistance value largely.
* Make sure that the sensor heater is at correct temperature.
