Hall effect sensor Wikipedia

A Hall effect sensor (or simply Hall sensor) is a type of sensor which detects the presence and magnitude of a magnetic field using the Hall output voltage of a Hall sensor is directly proportional to the strength of the field. It is named for the American physicist Edwin Hall.. Hall sensors are used for proximity sensing, positioning, speed detection, and current sensing applications.

Disconnecting O2 sensor, what happens? | TTORA Forum

Oct 09, 2006· When it takes 15 minutes to go closed that means the heater didnt do its job and it only went into closed loop because the exhaust finally got the sensor to warm to its 600 deg. operating temp. So one of three things. o2 sensor heater core is bad, the o2 wiring has a short or some malfunction, or the o2 itself needs complete replacement.
