Application
This A/F control sensor generates a voltage of between 0 and 1 V depending upon the concentration of oxygen in the exhaust gas, and is most widely used as the central part of current exhaust gas cleaning systems. It has high performance and high reliability that enable it to meet the strengthened exhaust gas regulations, and contributes to clean air.
This sensor uses a quick start type high power heater (※FLO/※※FLO (U) type) in addition to a standard type heater. It functions as soon as the engine key is turned ON, and can greatly reduce HC during a cold start, thus meeting the severe emission regulations subsequent to LEV.
This sensor has characteristics that cope with the exhaust gas components on the downstream side of the catalyst, and is also used for correcting the oxygen sensor on the upstream side of the catalyst which guarantees long-term low emission.

Features

• Is of compact design and has excellent mounting freedom.
• Has excellent deposit resistance and achieves long life.
• Has excellent low temperature performance, and achieves a wide operating temperature range.
• Has excellent sealability to prevent the ingress of gasoline and water.
• After the engine key is turned ON, FLO starts to operate within 15 seconds, and FLO (U) within 10 seconds (40 seconds in the case of the standard type).
  Long life is achieved in combination with heater control.
• Supports a sub-feedback system for applications downstream of the catalyst, and also OBD judgment.
