SV211 IAT Sensor Fault

[traves_peterson]

My 2008 SV211 TE is throwing a warning code/buzzer with the IAT Sensor Fault. My dealership said they have not seen this problem and don't want to use my boat as a guinea pig trying to figure it out. I have the Z6-390 engine with closed cooling, ~138 hours on the boat. Does anyone have any thoughts? I did replace the airflow sensor on a recommendation from another dealer but that didn't solve the problem. If anyone has ideas, I'd love to hear what may be causing this issue or where to start. Thanks in advance. I troll this forum daily and have found a ton of useful information, I'm sure someone on here has some ideas.

I don't have an answer to help you out... But am I the only one that thinks that's a pretty lame excuse from YOUR dealer to say ohh well we've never seen that and would rather not even bother to try and figure it out to help out a customer? I mean really? They should be able to fix or diagnose anything on the boat in my opinion. They are a Nautique dealer right?

I typed pleasurecraft and IAT FAULT in Google and got some kind of training guide. It has a section in it with these faults and probable causes , not sure this helps.

Thanks Tim, I'll have a look. I've been searching PCM and get many results but not targeted enough. Scooter, I agree it's lame. They are not a Nautique dealer but have sold and serviced many Nautiques. Not exactly sure what the deal is on not even wanting to try. I'll find someone willing.
