well i've been reading on here about wide band o2 sensors and i did some research. what i've found is that the wideband is faster and more accurate than a egular 02 sensor, also that they use more wires. im just kind of looking for a better understanding of wideband 02, can anyone help point me in the right direction?

The true value of a wide band is realized when tuning. It'* more accurate and allows you to adjust other dependent tuning tables to a tighter tolerance.

The standard O2 sensor is a narrow band O2, so it only looks threw a very small window to see the ratio. A wideband sees far more, there fore much better for tuning.

Proper operation on a narrow band is different than a wideband. The output valves are different etc.

Narrow band reports in millivolts between 0 and 1. It should always be fluctuating from low to high or say 200 to 700 to 150 to 800. The faster it flips, the better. A lethargic sensor is on it'* way out, and causing excessive fuel consumption. At rest or unplugged a NB o2 should read 450mV.

Wideband sensor reports from 0 to 5 volts and/or in Air Fuel Ratio (AFR). AFR is important and under normal cruising our pcm aims to maintain 14.7 AFR. This reading only fluctuates by the true AFR and does not bounce up and down from lean to rich like a NB.
