The stock O2 is a 2 wire sensor with a 1 volt range AFAIK and the Wideband O2 is a five wire sensor with a 5 volt range and is far more accurate for tuning your vehicle for heads/cams or forced induction and mods of that nature.

 

I thought our truck came with 4 wire o2 sensors. I changed mine not to long ago and they had 4 wires. I might be missing something though.

 

A stock sensor is a four wire. 1 for 12+ for the heater, 1 12- for heater gound, 1 for 0-1v to PCM, and 1 for sensor ground.

 

oh, ok thanks for clearing that up. later

 

Sorry my mistake on the stock O2 sensors. Not an expert just trying to help out didn't mean to be misleading and causing confusion.

I learn something new all the time. Sorry again for the incorrect information.
