I have been testing an HHO unit I built. I have an O2 sensor enhancer so I can add a little voltage to the signal for the O2 but wanted to make sure I have a narrow band O2 sensor. After reading for a bout an hour last night here and on an HHO forum I think mine might be narrow band, that is if the Haynes book is correct about the voltage. According to what I read, the narrow band has a very low, fluctuating voltage, less than 1 volt and the wide band has a lot more so I'm going on that premise to connect my O2 enhancer. Anyone know more please let me know, I'm not doing anything till the weekend so I have a lot of time to research this. It's on my 1998 Dakota 5.2 4X4.
