Alarms On A 5/0 Efi
 

Can anyone tell me why my alarm is going off on my 202 islander. the drive oil is full the water temp is good 160 and the oil pressure is 60 psi. we un hooked the oil sensor wires and the alarm still goes off. running easy every mile it beeps twice, when running hard it comes on and stays on, could it be a fuel problem . It is a 5/0 efi please help the leaves are changing color and we want to get a few more rides in. Thanks.

have to scan to be sure. If it only comes on above 3000 rpm could be a code 44 knock sensor. if above and below 3000 rpm have seen alot of H20 pressure sensors go bad.

thanks I will get it scaned

Water pressure?

My double beep alarm on my 496 was the IAC, Idle Air Control valve. Double beep about every 2-3 minutes.
