Warning beep


Recommended Posts

Good evening

Tks in advance for your reply….

I get a warning beep only when going over 30 MPH.  I dont get the warning beep when running neutral and 3000 RPM.  

Also, I did change the Crank, Cam, Knock sensors.  Unplug oil sensor… still get the warning beep!

any idea what could be the problem?

boat model: 2004 Malibue  LSV 25, 8.1 L

thank you

I have the same issue with me 2002 and can’t figure it out. I may find the beeper and poke it with a screwdriver to make it stop. It’s annoying for sure.

Using something like Rinda Diacom or Codemate to help diagnose the problem may be more helpful than replacing random sensors or poking things with a screwdriver.

BEEP CODES — the 4 maintenance items that can trigger the beeper are:

  •  High engine water temperature (NOT dash sensor, and >203*)
  •  Low oil pressure (NOT dash sensor, and <6 PSI)
  •  High transmission temperature (>140?*)
  •  A diagnostics trouble code

The last one can be many things, but the beep pattern may help diagnose it.

Thank you for the reply.

I am using the Rinda DIACOM and the warning beep I get does not generate a fault Code. 

Apparently, there is a description of warning Beep in Malibue user manual.

FInally, it was the Knock sensor......loose connector.

After changing 2 sensors with no result, I tried to unplug-plug back in the knock sensor and realised it was not connect properly (rusted)

Reconnected properly and back to normal.
