[Diy_efi] Could someone please explain Wide

[Scott Campbell]

All O2 sensors require heat to function properly.  Some narrowband O2 
sensors include self-regulating heaters and some do not.  Those without 
depend on heat from the exhaust to bring them up to operating temperature.

Since temperature is a key variable in the output response of an O2 
sensor, a wideband sensor controller will carefully control the 
temperature of the sensor.  If the sensor is located in a position where 
the exhaust gas is hotter than the optimum sensor temperature, the output 
of the sensor will be inaccurate.
