OXYGEN SENSOR CONTROL RESPONSIVE TO RESISTANCE AND IMPEDANCE |
| 摘要 |
Various methods are provided for operating an oxygen sensor. In one example, a method of operating an oxygen sensor including a heater comprises sampling a first heater resistance at a first temperature, and determining a resistance-temperature transfer function relating heater resistance to heater temperature based on the first heater resistance and a second heater resistance at a second temperature, the second temperature different from the first temperature. |
