2016 ar190 head change getting check engine light

[cc580]

I have a 2016 ar 190 with 370 hrs on it that was smoking. I brought it to a dealership who told me that it had a cracked head. it was running well other than the smoke. the dealership gave me a high price to fix it because they were going to use all Yamaha new part. I purchased a used complete head assemble on eBay that has 85 hrs on it. I installed the head with the engine in the boat and disconnected the intake manifold and the exhaust manifold bolts and left everything on the intake and exhaust assembled. I set the cams on the timing marks and set #1 cylinder at tdc with a dial indicator. when I started it up it ran rough and the check engine light came on. I thought I must have messed up the cam timing so I checked it and it is spot on. I have a maptuner x and I checked the error codes and the error codes are.

224 cam position sensor
241 engine management
240
52
1 overheat
131 accelerator position
3 ecu
49 over cooling

where do I start with these codes?

@Neutron may have some insight on those codes.

Would it be safe to say that you most likely got check engine and codes because the intake and exhaust weren't on the motor?

At first thought seeing so many codes i would think its a voltage or ground issue for the harness.
Double check the harness and connectors. If it isn't a wiring issue then start with the ecu codes and go from there. One is most likely causing all
