2003 dt225 check engine blinking code

[baldbob]

My check engine lite is giving a 3 then 4 lite blinking code. Cant get a real service manual till next week. Anyone know what this 3-4 check engine code is indicating? Happy Thanksgiving !

I think Suzuki has kept the error codes consistent
My df150:175 manual translates to a map sensor

Thank You

trying to find the map sensor now

Parts page not very helpful for this engine
It could be this part number
18590-94600 SENSOR, AIR PRE
But not 100% positive
Best bet is to get your hands on the service manual

Art 2 strokes don't use map sensors.
I'll see if my book indicates what the 3-4 code relates to.
But in the meanwhile, can try to Google "Suzuki outboard error codes". You might get a hit.
Good luck. Post back if you find out.

No MAP Sensor

Engine not wired. I'm now getting a TPS sensor error code. Replaced sensor, voltages are good but code not clearing. These engines are not easy to work on for sure !

The sensor needs to be set up like the manual explains, otherwise it may still give incorrect reading.
The 225 is different from my 140s, sorry.

Good luck.
