  1. Polaris Sportsman
    Hi all, Bought a used 2007 sportsman 700 EFI about 2 years ago and ever since I had it, it has been producing the same problem but getting worse over time. I have tried everything i can think of to resolve it. The quad used to generally start up fine but if i let it get too warm and idle then...
  2. Polaris Sportsman
    2014 Sportsmen 850HO Starts fine, idles fine. Under acceleration it bogs down and then the light comes on. Just like a TPS bad on a car. So I did my own work at 1st. Adjusted cable, cleaned connectors checked wires. It went away for a month then came back. So I took it to the dealer. They...

    Hi I recently bought a 500 sportsman and the first ride I went not far and after a few minutes the machine started backfiring and trying to stall. Took it to my shop and see the engine light is on. I researched and came with codes 22 and 47. I adjusted the throttle cable and the sensor seems...

    Quad is 2008 Sportsman 500 EFI....What happens with the quad is when I first start it up it idles and runs fine after quad warms up I notice a engine misfire at a specific RPM range of 4600 - 5100 below and above this range the quad runs fine. I'm wondering if the TPS has a issue where when it...

    I have a 2009 Sportsman 800 H.O EFI that all the sudden started running like junk. The machine is bone stock and only basic oil changes have been done to it. I have read a million post about the TPS and TBAP sensor harnesses are awful quality, so I started there and tested everything. I am...

    I am suffering from the dreaded check engine throttle sensor issues. All posts indicate a newer TPS will repair this - but I could not find anyone that could tell me if the newer TPS would fit my older bike. I have a 2010 850XP Sportsman - this TPS doesn't even come close to fitting. I paid...
  7. Polaris Outlaw
    I have a 2007 Polaris Outlaw 525 IRS and it had some issues in the fall when I rode it. It would stall if I jabbed the throttle. After doing literally everything I could have tried to make it run better... cleaning carb, cleaning needles, replacing carb boots, getting it to run great (not too...
  8. Polaris Sportsman
    I have a new Sporsman XP 850 H.O. and I was wondering if anyone knew the factory setting for the Throttle position sensor? I would imagine I need to test the voltage on my multimeter, but I don't know the correct volatge settings. Does anyone have the factory spec or know the voltage?
  9. Polaris Sportsman
    Has anyone heard of/experienced this: My 2012 Sportsman 400 will run fine, then suddenly start sputtering at speed. If I keep on the throttle, it will usually start missing, backfiring, and operating at what feels like half power. If I let off the throttle, it rolls to a stop and shuts off...
