Component Inspection

1. Check HO2S (B2/S1)) Heater resistance
(1) IG "OFF" and disconnect HO2S (B2/S1) connector
(2) Measure resistance between terminal 1 and 2 of HO2S (B2/S1) (Component Side)

Specification : 3.0 - 4.0 ohms at 21 °C (69.8 °F)





(3) Is the measured resistance within specification ?
