【Abstract】As an important part of closed-loop control，the switch oxygen sensor is mainly controlled by ECU in the application of EFI system.In the early stage，the main engine plants in China were packaged in the system，and the control of sensor heating was mainly in the hands of the overseas system EFI suppliers.In order to realize the unpacking of oxygen sensor system，it is urgent to realize the in-depth research and control of the heating control of oxygen sensor.Therefore，the heating strategy of switch oxygen sensor is studied in detail.

【Key words】switch type oxygen sensor;ZrO2;heating strategy
