Circuit description
The ecm compares the two waveforms of the heated oxygen sensors located before and after the catalyst to determine whether or not the catalyst performance has deteriorated. Air–fuel ratio feedback compensation keeps the waveform of the heated oxygen sensor in front of the catalyst alterna ...

Source voltage drop
The srs is equipped with a voltage–increase circuit (dc–dc converter) in the airbag sensor assy center in case the source voltage drops. When the battery voltage drops, the voltage–increase circuit (dc–dc converter) functions to increase the voltage of the srs to normal voltage. ...
