Step 2 (When indicating C44/P0135:)
1) Turn the ignition switch OFF.
2) Disconnect the HO2 sensor coupler.
3) Check the resistance between the terminals (White – White)
of the HO2 sensor.
! HO2 heater resistance: 6.5 – 8.9 Ω (at 23 °C/73.4 °F)
(White – White)
NOTE:
* Temperature of the sensor affects resistance value largely.
* Make sure that the sensor heater is at correct temperature.
" 09900-25008: Multi-circuit tester set
% Tester knob indication: Resistance (Ω)
Is the resistance OK?
4) After repairing the trouble, clear the DTC using SDS tool.

YES
• O/W or W/B wire open or shorted to ground, or
poor
A or
Z connection.
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
• 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.
