DF250AP check Throttle sistem message, error 7-3 and 3-2

[jozi-111]

I have purchased 2013 Beneteau Flyer 7.5 with 2012 DF250apxx - new engine not used until now... sometimes after cruising while idling i get 7-3 and 3-2 error and message: check throttle system.
Engine also runs verry odd and vibrates at idle then.
Only solution is to turn off and again on main switch, then is everything ok again.
Does anybody have similar problem or solution?
Thnx!

On the DF300AP the codes are:
7-3 ETV (Electronic Trottle Valve)
3-2 MAP Sensor 2 (Pressure Detect Passage)

Error 7-3 will trigger the fail-save mode while 3-2 will not.

As you have problems with bad running it seems thatg those error are real errors.

It seems that - at least the DF300AP - has problems with gost error messages generated by a software problem on 2016 engines using SMIS gauges.
You should have your dealer to pull the codes from the engine using the Suzuki SDS diagnostic software to verify if the errors apear also in the engine ECM.
If they don't appear in the engine ECU then you have the same problem as me and acdiii another users here.

Thank You for quick response.
The engine is 2012 built, first used 5 days ago and has only 3 hours.
I think it is ecu/electronic fault because restarting the engine dosen't help, but turning the main switch to off and on cures the problem...

Ok,
at this point you should go to a Suzuki dealer to check in depth the problem.
Probably a sticking/out of norm value MAP sensor and/or Trottle Valve as the engine was a long time stored.
There may be still a problem that there is a software problem with your SMIS gauges as they can be troublesome if the wrong software is installed.

It sounds like when the shifter is brought back to the idle position, the signal voltage in the shifter is different to the throttle position switch signal voltage on the throttle plate. Because there is no cable, or idle speed control motor, on start up the pcm will open the throttle around 18% and slowly drop to around 12% as the engine warms up. When coming off high revs and the shifter is brought into the idle position there is different signal voltages between the shifter and the throttle plate and the idle quality is bad, this would bring the map sensor code on because manifold vacuum will drop and signal voltage will rise. also if your engines have variable valve timing if the throttle position signal voltage is out, the camshafts wont lock in the idle position. When you disconnect the battery the pcm will go back to it's default settings.

Ok, thanks for explanation.
What is the possible cause for diferent voltages in shifter and throttle plate?

Sensor adjustment or two much movement in the shifter, maybe a faulty sensor, with out a scan tool, or in this case the Suzuki sds hooked up you will have know idea. Any engine system using electronic throttle control is impossible to diagnose a problem with out a scan tool. Driveability problems will arise with no codes or a check engine light coming on to tell you where to look, and unless you have a good scan tool you will be going know where.
