Post 07 500 Sportsman Check Engine light

Hi Guys.
I have a 500 EFI HO and it has developed a bit of an issue.
It started with a check engine light (which I did and found nothing a miss, so I started it up and it went away).
Later on that ride the bike developed a stall at low idle and became hard to start after it stalled, it would even blow a bit of blue / white smoke on getting it going.
At the end of the ride i noticed the ols spanner came up and was blinking so i knew it was due for a service.
This morning I went to start to warm up the oil for the service and the check engine light is back on and the bike was very hard to start again.
I checked the oil level and low and behold the oil level is way over full.
The coolant level is good (oil is not milky) but i would hazard a guess that it will be fuel in the oil as it does smell a little that way.
Any one able to tell me how to pull up the fault code and test my injection system to see where my issue lays?
Regards Fuzzybear

Try draining the oil & refill it with new oil. 2qts should all be needed, mine had a similar problem & thats what I did. Welcome to the forum!

Unhappy

Ok Service done but I still have a "Check Engine" on.
I removed the fuel tank and cleaned out all the old fuel and refilled it.
It is idling now but it does have a bit of a flat spot just above idle and will often die with a bit of a back fire?

07 500 Sportsman Check Engine light

Check the boot connections between the throttle body and the engine.

What code is it?

Based on your symptoms I would guess it's the MAP sensor or its wiring harness. The wires tend to break inside the insulation at or near the sensor. They will look good but if you tug on them a broken one will feel stretchy. A better than oem replacement harness can be had at http://otbpowersports.com/

07 500 Sportsman Check Engine light

To get the code turn the key on 3 times in 5 seconds leaving it on the third time. Count the blinks of the check engine light and write it down. There will be a slight delay between digits. E.g. 1-2-2-1-5-2-6-1.

The codes are 13, 45, 46, & 61.

I've never seen 13 but I'm pretty sure it's just a marker to begin the sequence. 61 means it's the end.

45 and 46 are both for the MAP sensor low and high input respectively. That means your voltage signal from the MAP sensor is all over the place or nonexistent at times. The sensor itself would be really hard to damage so I suspect the wiring harness is bad. It's a very common problem.

I would replace it with the one at the link I posted earlier. It's really easy and comes with everything you need.

I know one of my efi 500 s were acting strange years ago. I would ride then quad would act up and sputter then the needle on gauge would blink. After 3 months of issues I figured out my stator was bad. But you don't have that issue otherwise your battery would always be dead because not charging. Someone told me once a low battery does affect efi machines more than others becuase it depends so much on good voltage. Check that you battery is good and that its getting charged........just thought......
