OXYGEN SENSOR HEATER INSPECTION
1) Disconnect sensor connector.
2) Using ohmmeter, measure resistance between terminals
"V " and "GND" of sensor connector.
B
If found faulty, replace oxygen sensor.
NOTE:
Temperature of sensor affects resistance value largely.
Make sure that sensor heater is at correct temperature.
Resistance of oxygen sensor heater
HO2S-1 : 5.0 – 6.4 Ω Ω Ω Ω at 20 °C, 68 °F
HO2S-2 : 11.7 – 14.3 Ω Ω Ω Ω at 20 °C, 68 °F
1. Viewed from terminal side
3) Connect sensor connector securely.
