i am installing a wideband o2 in my 93 240sx se. i am haveing problems with the 0-1 volt output on the wide band so i conected a volt meter to it to see what it was reading. i was geting as high as 1.3 volts so i disconected the o2 meter and cheacked the voltage on the ECU side of the wiring harnes and it read .3 volts? whats up with this? did not think i would get voltage out of the ecu on the o2 sensor wire. could you guys check your cars and see if you get any voltage out of the ecu side of the plug to your o2 sensor? it would help me a lot. mabe my ecu is bad or the wireing harnes. thanks
