Me thinks it's time to replace my O2 sensor. Mine is a one-wire sensor. Would it make any sense to install a three-wire sensor assuming that it will send more accurate readings sooner than an unheated one? How would the two-wires for the heater be installed? Would it confuse the ECU or are the sensors the same other than the heater?

    stick to what it calls for. the heated sensor brings the sensor to working temperature nominally faster than yours.

    in this drivers opinion a distinction without a meaningful difference.

      I agree. Little if any difference warming up. My old 84 had a 3 wire whereas the current one does not. There was a shift in a few of the FI components late in the that model year, and the O2 sensor was one of them.

      Actually, there is a difference your wallet will notice.
