It can’t be the right part. There has to be a cross reference issue etc. I would double check your numbers.  18 to 26 mm not clicking. The TPS is a very temperamental part so  should get numbers re checked and the calibration tool as well from Amazon so it’s installed properly.

Post a pic I’m curious to see what it looks like. I’m curious about the dimensions. We may be talking about thickness (26mm) of the sensor and not the circumference? 

I guess  you would have to see the dimensions of the part to be sure

It looks like it will fit.  Only way to be sure obviously is to try it.  

But i would measure it first before you slap it on and see what the numbers look like.  

Quick question. What’s the part number on the original one.

I looked up the part number and it’s showing that the 26mm does indeed fit so I think your good to go.

So I’ve looked everywhere and it all comes up the same. The old number is superseded by the new number. The old part is roughly 0.7 mm or 3/4 of an inch in diameter and the new one is 26mm or 1.02 inches in diameter. Very strange.   

I was looking on eBay and found the part number for the oem one and it’s available if you want to take a chance?

Frank  we had to put a spacer between the tabs and the throttle body, but it does work, not real thrilled with the setup but it is stable sealed and working

Ok that would make sense. I was wondering about maybe possibly spacer.  But did the spacer come with it ? 

Also how thick was the spacer ? I know that the shaft coming out of the throttle body is only so long? 

Lastly did the new sensor have any paper work that mentions anything about the spacer? I would reach out to the Polaris via email and let them know about this problem and the aggravation it’s caused. Pain and suffering damages of not being able to ride!!!!! Lol. 

Nice work brother, ride safe.

      We had an issue with the lights working on occasion.  Then they just stopped working completely (front and rear). We looked at the EFI fuse and it was melted, but not blown.  We replaced the fuse, but now the ignition will not turn on UNLESS we pull the fuse out...and BTW, the lights still didn't work with the new fuse. Any help would be appreciated. Thanks!

      Hello all just recently acquired this atv which as you can see in the pics that it has had an unsheltered life. i did get it running and put some used tires on the front.
      It still needs a bit more well needed maintenance, chains tightened and oiled. needs an airbox or air cleaner and other misc items.

      I have a 2017 Sportsman 570 SP with a power steering issue. Dealer tells me my machine is one that is not covered by recall and offers no help other than bring it in they will look at it. Any ideas?

      Hi, I am having the hardest time figuring out where and how to line up the flywheel for TDC on my sons 2019 Sportsman. The older models where much easier and the identification marks are self explanatory but this ones different and I can’t find a service manual. Any help would be awesome?

      Does anybody know how to determine which of the 2 key blanks fits my ATV. I have called several dealers, and Polaris and nobody seems to know which key fits which ATV. I thought with the ViN number they could look it up, but apparently not. I hate to spend the money at Polaris for a key blank and then pay a locksmith to cut it, but the locksmiths around me don't have the Polaris keys in stock. I find them on Amazon and places, but I can't tell which key blank is right for my ATV. Any help would be appreciated.
