HEATED OXGEN SENSOR (HO2S) INSPECTION (FOR E-02, 19, 24)

• Disconnect the HO2 sensor lead wire coupler. (!5-79)
• Inspect the HO2 sensor and its circuit referring to flow table of
the malfunction code

" Resistance: 4.0 – 5.5 Ω at 23 °C (73.4 °F)
(White – White)
# 09900-25008: Multi-circuit tester set
$ Tester knob indication: Resistance (Ω)
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.
