2. Select "FUEL INJECTION" in "ACTIVE TEST" mode, and select "RR O2 SEN-B2" as the monitor item with CONSULT.
3. Check "RR O2 SEN-B2" at idle speed when adjusting "FUEL INJECTION" to ±25%.
-
"RR O2 SEN-B2" should be above 0.48V at least once when the "FUEL INJECTION" is ±25%.
-
"RR 02 SEN-B2" should be below 0.43V at least once when the "FUEL INJECTION" is ±25%.
Without Tools
1. Start engine and warm it up sufficiently.
2. Set voltmeter probes between ECM terminals (66) (sensor signal) and (43) (engine ground).
3. Check the voltage when racing up to 4,000 rpm under no load at least 10 times. (depress and release accelerator pedal as soon as possible)
-
The voltage should be above 0.48V and below 0.43V at least once during this procedure.
-
If the voltage can be confirmed in step 3, step 4 is not necessary.
Reference Data
4. Keep vehicle at idling for 10 minutes, then check the voltage. Or check the voltage when coasting from 80 km/h (50 MPH) in 3rd gear position.
-
The voltage should be above 0.48V and below 0.43V at least once during this procedure.
