I got an 07 250 Pro XS. I have an alarm going off,says fault 15 manifold absolute pressure sensor. Any idea what this is and how serious?

i would post this in bassboatcentral.com under the 3 liter merc section. Ask Don Weed and provide a serial number with your question. He is an awesome guy and very very helpful.

Where do you see the code when the alarm goes off?

The fault 15 reads out on the gauges on the console along with the absolute manifold sensor.

The reason I ask is I had an alarm go off this past weekend but no code on the smart craft gauge.

indicates a map problem if it was critical it would put you in guardian but I would get it looked at soon it could affect MPG and possibly a little loss @ WOT
