Active Engine Faults

Recommended Posts

I have a 2013 LSV with the 450 Corvette motor. 
I’m getting an engine fault code 

SPN 65566. 
Can you please tell me what this means? 
Boat runs great, oil pressure good and temp good. 
thank you.

Look through this, but I think that's something with the fuel management. 

Action Taken When the SPN Sets

SPNs 65565 and 65566 are Type B SPNs.

Conditions for Clearing the SPN

SPNs 65565 and 65566 are Type B SPNs.

Diagnostic Aids

• The system will become lean if a fuel injector is not supplying enough fuel.

• A lean condition could be present during high fuel demand due to a fuel pump that does not deliver enough fuel, a plugged fuel filter, or a restricted fuel pipe.

• The system will become rich if a fuel injector is supplying too much fuel.

• Review the Freeze Frame/Failure Records with a scan tool.

Doubt it. It looks like that code means it’s starving for fuel. Maybe even a vapor lock?  These are just maybes, I am not a professional, but I’ve been tinkering with these boats for 20 years. I would need to put it on a scan tool or you need to take it to the dealer. Anything fuel related I wouldn’t want to take a chance on. 

I have a Diacom scan tool your welcome to borrow, but I already have a guy on this forum I offered it to.  So when he’s done your welcome to borrow it. But please give it back when your done...lol.

Wow. I really appreciate all your help but I’m located in Theodosia, MO. 
I think I’m gonna call the local marine in town and see if they have a scan tool. 
how much does a scan tool cost?
