O2S Test Result
Refer to PRE-CHECK for detailed information.
Rear HO2S Voltage:
If the value is out of the standard value, the ECM interprets this as a malfunction and sets DTC.
O2S TEST RESULT (REAR HO2S VOLTAGE)
| TEST ID | Description of TEST DATA | Conversion Factor | Unit | Standard Value |
|---|---|---|---|---|
| $07 | Minimum rear HO2S voltage | N/A | V | Below 0.45 V |
| $08 | Maximum rear HO2S voltage | N/A | V | 0.6 V or more |
| $31 | Time that rear HO2S output changes Lean to Rich | N/A | sec. | Below 3 sec. |
| $32 | Time that rear HO2S output changes Rich to Lean | N/A | sec. | Below 3 sec. |
Rear HO2S Slow Response:
If the time is out of the standard value, the ECM interprets this as a malfunction and sets DTC.
O2S TEST RESULT (REAR HO2S SLOW RESPONSE)
| TEST ID | Description of TEST DATA | Conversion Factor | Unit | Standard Value |
|---|---|---|---|---|
| $37 | Time until rear HO2S voltage drops to below 0.2 V after fuel-cut starting | N/A | sec. | Below 7 sec. |
Rear HO2S Low Voltage:
If all the values ($81, $84, $85 and $87) are out of the standard values, the ECM interprets this as a malfunction and sets DTC.
O2S TEST RESULT (REAR HO2S LOW VOLTAGE)
| TEST ID | Description of TEST DATA | Conversion Factor | Unit | Standard Value |
|---|---|---|---|---|
| $81 | Percentage in monitor time where rear HO2S voltage is below 0.05 V | Multiply 0.3906 | % | Within 60% |
| $84 | Percentage in monitor time where rear HO2S voltage is 0.7 V or more | Multiply 0.3906 | % | 20% or more |
| $85 | Continuous time that rear HO2S voltage is 0.45 V or more | Multiply 0.2621 | sec. | 20 sec. or more |
| $87 | Percentage in monitor time where rear HO2S voltage is 0.45 V or more | Multiply 0.3906 | % | 40% or more |
