Yamaha F150 error code 18

[aldo]

Can anybody tell me the meaning of error code 18 in a Yamaha F150, before I'm able to get official assistance on Monday?

TIA

P.S.: I'm posting in every forum I know since I'm quit anxious to know what happened today. The gauge flashed 'check engine' and cutted rpm and I had to go back with one engine at 8 kts...

Not sure if Yamaha uses the same fault codes across their lineup, but my 2005 Yamaha 300 HPDI manual says 18 would be a "Incorrect throttle position sensor". My guess is Yamaha would use the same codes.

Thank you, Ludicrous, for the quick answer. I'm not sure if a two stroke could have the same error codes as a four. Nevertheless it seems reasonable, since I had some difficulties, before the alert started, to sincronize rpm on the faulting engine...

Let me know how it worked out.

Code 18 is a throttle position sensor on your F150.

Mud Runner, thank you very much for the confirmation of the code. That's very reassuring for me.
