Typical Scan Tool Data
HO2S 1
| Circuit | Short to Ground | Open | Short to Voltage |
|---|---|---|---|
| Operating Conditions:
Engine operating in Closed Loop Parameter Normal Range: Fluctuates between 3.2-3.4 volts/1.0 Lambda |

| HO2S 1 Input | 1.232 Lambda/4.99 volts* | 0.999 Lambda/3.3-3.4 volts | 0.999 Lambda/0.00 volts** |
| Low Reference | 1.232 Lambda/4.99 volts* | 0.999 Lambda/2.9-3.2 volts | 0.999 Lambda/0.00 volts** |
| *Actual circuit voltage is not the same as scan tool displayed voltage **Actual circuit voltage is not the same as scan tool displayed voltage. Once DTC sets displayed voltage may default to fixed 3.30 volts. |
