A plug type device with an electronic connector or contact at one end, a wrenching facility in the middle. The opposite end may be threaded with a probe device. It is designed to change its output voltage as the exhaust gas to oxygen content changes when compared to the oxygen content of the atmosphere. A constantly changing voltage signal is sent to the electronic control assembly and microprocessor control unit for analysis and adjustment of the air/fuel ratio.
