Alarm sounds at higher speed/RPMs


Recommended Posts

MNMalibudad

I have a 2004 Malibu LSV with an Indmar Monsoon 340 engine with around 300 hours. Every time the engine  gets  into either higher RPMs or speed the alarm sounds and if I bring it down and turn it off and restart it  the alarm goes away.Any suggestions on how to fix it would be amazing?

 Got it fixed thank you everybody it was a knock out sensor 

This is an amazing form

Using a diagnostic computer to determine if there is a fault code may help point you in the right direction.  I would check the knock sensors first and make sure the harness is connected to them.  That is just a guess, if coarse.
