Map sensor error

[Rejean22]

I'm having map sensor issues on one of my engines and the result is rough or stall when idling. I tried switching the sensors between the two engines and the problem remains with my starboard engine. The code at the helm is 2 beeps followed by 3 beeps. The computer returns a map sensor issue.

Your assistance would be greatly appreciated

Check wiring to sensor.

I'm pretty sure I eliminated that. I also switched the Air Temp sensors and it did not improve. I'm just wondering what could cause the manifold air pressure to go awry.

Thanks

Same issue

Hello,

My name is Chris and this is my first post. I am having the same issue with my 05 DF140. It has a rough idle after getting warm. It is throwing 1 beep followed by 3 beeps. If I am correct is this a Map sensor error as well. I looked at my owners manual and I believe that is the code it is throwing. Any help will be much appreciated.
