Exhaust cam Sensor

[Chad76]

Hey fellas, Need some input. I just took boat out for first time in about 3 months it ran great, but I has a warning pop up EXHAUST CAM SENSOR. The boat continued to run fine and no issues what so ever besides it kept popping up. Any ideas. I am gonna carrying it in as it is under warranty boat is 2015 SE 450. Thanks in advance.

Don't ready about that much. Usually it's some obscure fault code that ends up with the bad O2 sensor.

I would assume the fault code is stored. The dealer will probably put a ohmmeter on the sensors (crank/cam) to test it out. Or will probably replace the part.
