HELP! 2017 outlander 650 RPM jump
So I have a 2017 outlander 650 that runs great idles great besides you can not hold rpm anywhere from about 1800-2800 rpm. If you slowly move throttle once it gets up to 1800 it just jumps up. Same thing decelerating. I have read every post I can find. Seems like couple other people have had this but haven’t seen post on the fix. I leaning towards getting new idle air control valve. I put volt meter on throttle position sensor and seems smooth with no dead spots. Any help much appreciated.

Welcome to the site!
As long as your throttle cable/butterfly in the intake is stroking free and returning to stop, IAC is about the only other thing this could be
That's what I was going to recommend. You can remove it from the intake and attempt to clean it/verify it's moving freely not sticking. There's a couple threads floating around here, one's real good, pictures n all. Search for IAC.

So you tested ohms? You need to test ohms with this table. You could check the IAC valve also.

Ok thanks a ton. this is exactly the information I was wanting. So first of all I did remove the IAC and verified it is moving but that's about all I did. I will check the resistance on it. So when I checked the TPS I just dc volts and watch the voltage rise smoothly from about .45 volts up to about 4.5 volts roughly. Do I need the ECM adapter tool to check the resister on the TPS. It looks like I can just test the pins can't I?

Thanks a ton, So I dont have the ECM adapter tool and doesnt seem worth it yet for me. I did go and test the resistance on the IAC. It reads right around 50. I had it out and kind of pressed on the plunger is what I would call it. Put it back in and it was kind of all over the place idling. which I expected. it settled down but then running the throttle up and down it was the same only worse. I'm fairly confident its the IAC and probably first thing i'm going to replace. If its not will get a TPS as they arent that expensive. I will report back once I get a sensor but going to be mid next week before I get a new IAC
You can replace the IAC without fuss, but if you remove the TPS, you will have to re-zero the sweep via BUDS

Well i'm still waiting on an IAC that I ordered but it kind of hit me to try and go run the machine while covering up the hole in the throttle body to the IAC. So I started it and as i started to cover the hole i gave it a little throttle as i knew it would die. I then completely covered the hole and ran the throttle up and down. I was able to hit all RPM and hold around 2000 if I wanted. I assume this gives me a pretty good idea that it is in fact the IAC. We will find out next week though. Thanks again for all the help
Where did you order it from?

Ordered from local dealership. Thought about an Chinese made one for cheap but my father in laws machine that I borrow so not worth it. He wants the oem.
For the sake of saying it, check Rocky Mountain ATV and Partzilla for the best prices on OEM BRP stuff.
Sometimes the local dealer route makes sense too, but they rarely sell below full list, unlike those two ^

Little update for anyone that cares. I installed the new IAC and it significantly smoothed out the throttle. This wheeler still has an aggressive engine brake and pretty high torque but it made it so much better. Thanks for all the help.
So problem fully solved?
