With fuel prices rising, the need for accurate air/fuel mixture monitoring is more important than ever. The engine computer needs to know what the fuel mixture is with a high degree of precision so it ...

前回STEP16ではブレーキスイッチ信号を入力しクルーズコントロールや、アイドルアップ制御の準備が進みました。 今回は純正のナローバンド O2センサー 信号をLINK ECUに入力します。 HA22Sの純正ECUピンアサイン 34PINコネクタの24番 OXがO2センサ信号になってい ...

An O2 or lambda simulator is used to send a simulated oxygen/lambda sensor signal to an engine ECU running in closed loop mode. O2 sensors generate voltages between 0.9V (rich) and 0.1V (lean). A ...

The days of the zirconia upstream oxygen sensor are behind us. Vehicle manufacturers have moved to what is commonly known as the air/fuel ratio sensor, or AFS. With the change in technology has come a ...

While oxygen sensors have been an indelible part of automotive technology for decades, the technology continues to evolve. In general, an O2 sensor relies on the fact that when the zirconium dioxide ...

Thought’s not the only maker of planar oxygen sensors– virtually every major supplier manufactures them for their OE customers–the announcement by Delphi that it would be offering planar oxygen ...
