  • Oxygen sensors failed - 140 hp 4 stroke

    hello, have a 140 Hp Stroke - 2015 MY - the oxygen Sensor was replaced a few months ago and now it needs to be replaced again - any issues with them ? Code 3-6 on gage and an alarm.

    They replaced 3 of them on mine till they figured out the ecm was throwing false codes. replaced ecm and no problems since.

      There was an ecm recall back when they came out, as well as an upgraded oxygen sensor design. Make sure that both have been fitted.

        When you say ECM - do you mean the main computer ? Thanks !

          Yes, that is it.

            Where can you find recalls for the Suzuki outboards? I just replaced my O2 sensor with the newer version and holder and want to be sure there is not an ECM issue. I have a '12/'13 DF115A.

            Thanks!
