    bought a 93 del sol si with a d16z6 in it..
    car only runs one o2 sensor..well its got a brand new bosch o2 in it but it still throws code 41(o2 heater malfunction)even after resetting the ecu so im thinking its wired wrong..so im trying to figure out which wires are supposed to be what..
    i already know the wires for the actual o2..now i need to figure out the wires for the engine harness.
    orange with black stripe-
    green with white stripe-
    yellow with black stripe-
    solid white-

    for the o2 its
    black-signal to ecu
    grey-ground

    its wired wrong because it is a bosch 4 wire universal o2..honda does not use 4 wire universal from the factory..this is a new o2 where you wire it to a plug yourself..
    thanx for the info but it wasnt what i needed..

    Could still be the sensor itself. I went through 3 or 4 Bosch ones in one year due their heaters failing.
