before it starts. 11. Drive the vehicle at 32 km/h (20 mph) or more and maintain a constant speed for 2 minutes or more. 12. After this driving make sure that the Data List "Alcohol Density Learning" is "Compl". 13. Monitor the output voltages of the A/F and HO2 sensors (AFS Voltage B1S1 and O2S B1S2 or AFS Voltage B2S1 and O2S B2S2) displayed on the Techstream. Result RESULT REFERENCE Sensor Output Reference Values SENSOR OUTPUT REFERENCE VALUES Reference values when normal (E0 Fuel) SENSOR OUTPUT REFERENCE VALUES - NORMAL (E0 FUEL) Result Proceed to A/F sensor and O2 sensor output both consistently indicate rich or lean C Except above B HINT: *1: Aggregate fuel trim is approximately equal to the following: Short FT + ((1 + Air-fuel Ratio A/F Sensor HO2 Sensor Lean Higher than 3.25 V Below 0.4 V Rich Below 3.25 V Higher than 0.55 V AFS Voltage B1 S1 3.28 V AFS Voltage B2 S1 3.28 V O2S B1 S2 0.76 V O2S B2 S2 0.70 V Short FT #1 1% Long FT #1 -6% Short FT #2 2% Long FT #2 -6% AF Lambda B1 S1 0.99 AF Lambda B2 S1 0.99 Alcohol Density Estimate 0%
