2006 5.0 MPI. Had just refilled. Alarm every minute or so

Neutral invoked immediate stall, no wind thankfully.

The only two guesses I have are sender unit or water.


Gauges all normal, water temp a little low at 160

I believe when it is going off every minute it is in guardian mode!

If you have access to a scan tool that would help narrow it dwn prety quick! Doesn't sound like its a fluid alarm, but would check all anyway!

Well I was going to pull it this week for cleaning. Someone must have told the boat it is for sale. Hopefully my marina guy has the scan tool, I hate guess and spend.

I hear ya, nothing worse than throwing money at it and still having the same problem!

Good luck!

Have to check this out soon. What kind of alarm do you get with gear lube level?

Gear oil is a constant buz

Most likely the IAC is bad.

It wasn't constant, about once every minute or so. I had always wondered how loud they are, THEY ARE LOUD! Thankfully, I made it to the dock, even if the bow was almost impaled on a windlass.

I've heard about bad idle control valves, is that what the IAC is?

+ 1 if it stalled its the IAC.
