5-69)
• Inspect the HO2 sensor and its circuit referring to flow table of
the malfunction code C44 (P0130/P0135).
• Check the resistance between the terminals of the HO2 sen-
sor.

If the resistance is not within the standard range, replace the
HO2 sensor with a new one.
NOTE:
* Temperature of the sensor affects resistance value largely.
* Make sure that the sensor heater is at correct temperature.
