4-72 FI SYSTEM DIAGNOSIS
4) Disconnect the HO2 sensor coupler and measure the resis-
tance between terminals. If the resistance is not specified
value, replace the HO2 sensor with a new one.
 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 atmospheric tempera-
ture.
