2016 Sundancer 280 Mercruser 6.2L. I installed the Vessel View Mobile so I could figure out why my OBD Service Soon warning is showing on my smartcraft dash guages. The Mercury Vessel View Mobile is showing Fault Code 945-6 Catalyst oxygen storage capacity port.
Is this an O2 sensor? Is there a way to test my O2 sensors to determine which one may be causeing the fault code.
