CHECK HEATED OXYGEN SENSOR 2

With CONSULT

1. Turn ignition switch ON and select “DATA MONITOR” mode of “ENGINE” using CONSULT.

2. Start engine and warm it up to normal operating temperature.

3. Turn ignition switch OFF and wait at least 10 seconds.

4. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.

5. Let engine idle for 1 minute.

6. Select “FUEL INJECTION” in “ACTIVE TEST” mode of “ENGINE” using CONSULT, and select “HO2S2 (B1)” as the monitor item with CONSULT.

7. Check “HO2S2 (B1)” at idle speed when adjusting “FUEL INJECTION” to ± 25%.

   

   “HO2S2 (B1)” should be above 0.71 V at least once when the “FUEL INJECTION” is + 25%.

   “HO2S2 (B1)” should be below 0.18 V at least once when the “FUEL INJECTION” is − 25%.
