O2S Test Result

Rear O2S (Bank 1 Sensor 2 and Bank 2 sensor 2) voltage monitor 

O2S HST RESULT

TEST DATA Description of TEST DATA Conversion Factor Unit Standard Value of TEST LIMIT
MIN O2S V The minimum voltage during O2S monitoring N/A V Between 0 and 0.4 V
MAX O2S V The maximum voltage during O2S monitoring N/A V Between 0.5 and 1.275 V

If the sensor voltage is out of the standard value, the ECM interprets this as a malfunction.

Rear O2S (Bank 1 Sensor 2 and Bank 2 sensor 2) crack monitor 

O2S HST RESULT

TEST DATA Description of TEST DATA Conversion Factor Unit Standard Value of TEST LIMIT
Time $81 Percentage in monitoring time where oxygen sensor voltage is less than 0.05 V Multiply 0.3906 Between 0 and 60 %
Time $84 Percentage in monitoring time where oxygen sensor voltage is 0.70 V or more Multiply 0.3906 Between 20 and 100 %
Time $85 Maximum Rich (gtequal 0.45 V) time Multiply 0.2621 Second Between 20 and 66.8 seconds

If all the values ($81, $84 and $85) are out of the standard values, the ECM interprets this as a malfunction.
