    I have a 2002 35 Cabo flybridge with 3126b cats in it. If the motors are off and ignition is on the orange diagnostic light give me 43 as a code. Code 43 says open or short circuit of injection actuation pressure sensor. Motor starts fine and seems to run fine any help would be appreciated.

    Time to get a CAT mechanic out to your boat. Between this and the gauges, you have a wiring issue on your engine. A good CAT mechanic can probably find and fix it within an hour or two.

    Agree, this is not something you are going to diagnose or fix on your own. It could be as simple as a bad sensor or injector or it could be a bad ECM.
