DF140 with Map sensor faults

[boatmangc]

Setting MAP sensor fault, replaced MAP sensor, Same problem
On Suzuki diagnostics while watching MAP if throttle position is moved MAP readings change, both with the old sensor and the new.
Harness?
ECU?

Error code 1 or 2

I don't remember right off hand
What's the difference and what should I look for from each if you don't mind?

[catacom225]

map sensor 1 code 3-4= receiving no signal with engin running map sensor 2 pressure detect passage code = 3-2 remove and clean detect pressure passage

These conditions will be caused by IAC valve failure or incorrect
by-pass air screw adjustment. If IAC valve is always closed
or by-pass air is too low, the ECM controls the IAC valve duty
to increase to maintain the idling / trolling speed specified.
NOTE 2:Map error 3-2
This condition will be caused by clogged pressure detect passage
in intake manifold.

Final outcome.
When I looked at the motor the client was there and wanting to save some bux.
I found the Map sensor code and let him buy and install the sensor.
When I got back to it the Map code was gone and the motor was idling @ 1100 or so. The alarm was sounding but no codes were present.
Reset idle with fixed timing @ 650. Restarted the motor and all is good!

suzuki's always fixes the codes when you fix the problem
