    When the buzzer is going off, press and hold the button on the cluster until a two digit number appears. Report back what the number is and that will help diagnose the issue.

    Ultra,whats your rpm.Whats the EFI settings at? An EFI controller with just a milled head has to be killing your performance.Let us know if any codes.

    No code showing on display! Just check engine. Could the display be broken?

    Was the ski smoking and running real rich when it initially happened? Ive had both 15 (engine temp) and 18 (TPS) both go off and did not see them on the screen. The only way to see them was data logging the YDS software... 15 makes the ski run really rich and sluggish and smoke a bunch... Tps wont usually allow it to start... Most of the times Ive had codes like this it was due to a bad ground or corroded connection

    ok i just found the code sticky and the 01 is normal! but now the ski has no check engine, and it was doing it earlier today. i think im going to ride it for a while tomorrow and see what it does. i hooked it up to a hose for about 10min and nothing!

    Do you have a resistor in there to by pass the temp sensor?
