I've been getting this limp mode problem on the new motor that I've been trying to diagnose. The boat ran fine for 2 days last year before going into limp mode. I've been limited on time, so haven't really been screwing with it because I was sureeee it was the EIDBS system sensing a dead house battery. But that wasn't the problem apparently. I've also had a dead oil pressure gauge but had a mechanical gauge installed and it showed good, so I wasn't concerned. In addition the sending unit (I can only find one, although I think someone mentioned there is 2 on this motor...06 340 MP) is brand new. New batteries and the boat went into limp mode again after about 20 mins. Well I decided to swap out the gauge and in a pinch purchased 100 psi gauge from O'reilly's b/c it's all they had in stock that even remotely matched. It came with it's own sending unit since it was a 100 psi gauge, I knew I'd need a diff. one anyways. Well problem is now gone.
So the 2 things that have changed that cured the problem..... I've changed the sending unit and I've put in a new gauge. I guess it's possible I got a bad sending unit, but what are the chances the thing went bad after 2 days????
So that's why I'm wondering if there is anyways possible for the motor to sense the gauge is reading 0 psi and throw it into limp mode?
