I have been reading about upgrading to a 3 wire o2 sensor. I do have a few questions. First off what are the benifits of doing this. Ive read mixed reviews on them.
2nd how do you wire them up. Is it just a power ground and signal? I have plugs and pins at work to make a plug for it so thats not a big deal. From what i can see in pictures there are 2 wires are the same color and one is blue or pink. Im assuming the 1 wire that is different is the signal.
3rd how does the heater portion of it know when to turn off? Is there something in there that turns it off when it hits a certain temp or is it just on all the time? If it is on all the time how does it not burn itself out.
