hi Guys,i,ve had problems with my summit hanging rpms when clutching in over 4500 rpm.once i hit 4500-5000 rpm and let the throttle go it just hangs there.....I have to shut it down to get rid of the hanging.I've checked all cables,accelerator and clutch components and everything seems A1. Anyone having the same problems or have any thing I could try to fix this?  thanks for any help.

TPS is out of range.  Shop time.

The first thing to check for  if a vehicle exhibits higher than normal idling RPM is throttle cable free play.  It is extremely important to have the proper free play.

 

 

E-TEC engines have an idle governor designed into the ECM mapping.

This idle governor controls the idling speed to around 1100-1200 RPM once the engine is warm.

If a vehicle seems to have a high idle [2,000- 2,500] RPM or the idle speed seems to hang or slowly come down, a few items need to be checked.

In order for the idle governor to function correctly, a few parameters must be met:

  • The TPS must be between 0 and 0.5 degrees.
  • The RPM must be below 2,500 when cold or 2,000 when warm.
  • If these conditions are met the idle speed should be governed accurately.
The first thing to check for  if a vehicle exhibits higher than normal idling RPM is throttle cable free play.  It is extremely important to have the proper free play.  Consult the shop manual for proper setting.
 

Next check the closed throttle TPS reading (you will need to take it the shop for this)

It must be  at 0 or at least less than 0.5 degrees.

If not reset the closed TPS setting using the appropriate shop manual.

If these parameters are met and the engine continues to idle higher than normal, replace the TPS.

There is another thread going on this subject.

My sled hangs at 5000 rpms regardless of stock clutching or my clutch kit.  Sometimes I have had to grab the brake to slow the sled down.

Did you find the issue ?? I’m having similar issue on a ‘16 Etec 800. Hangs in that 4-5k rpm for a second on its way down

Did you find your issue. Just stumbled across this today. Never even heard of the problem and I've fixed a whole bunch of e-tec issues since they came out.

Hey there , well I switched from Polaris /team clutches and I think I’ve learned that it is just how the doo clutches feel. The engine braking part of it , like they stay revved up a little to keep the primary engaged /more so then a team clutch

mine bogged a little after it was idling high at around 3100 it went away after a little but all I did to fix the high idling is pin the throttle in an out while it was off I dont seem to have the problem anymore

Maybe DJ was referring to me. I had an abnormal amount of cruise control when I let off the gas. Took way to long to come down to idle without using the brake. It was not a throttle issue either.

Mine is a 800 ptek but if the Rave system is the same, I had a check valve in the wrong direction. That was my fault and was pulling my hair out. Turned out when I rebuilt the crank shortly after I got it, I assembled it wrong. There’s a number of diagrams online to use as a reference that I found. If you have not had a reason to pull the motor or change the vacuum/pressure lines, it would probably be something else, but worth a check.

Brilliant! The 2013 E-TEC employs a manifold to simplify the spaghetti mess of tubes and check valves, and this manifold is prone to failure.

Did anyone ever find the solution to this? Mine hangs at 5000rpm anytime I rev it over that for about 2 seconds then returns to idle. I've metered the TPS it was also reset with buds. Down a leak down test. But it's running rich. I pulled the airbox and verified the butterflys are closed fully and still revs 5000rpm for 2 seconds before returning to idle.

Probably different, but my 800r does something similar. I start it and it revs up to clutch engagement rpms on its own. I can push the throttle plates and they are fully closed.

I wonder if the throttle plates are not closing fully and need cleaning.

For what its worth....My wifes 2014 Summit 600 XM had this same problem. Ran fine, but would hang around 2500-3000 RPM when the throttle was released, then slowly work its way down to a somewhat regular/irregular idle. Turned out to be a faulty AIR INTAKE TEMPERATURE SENSOR. Super easy fix and only cost me $20. Everything is running fine now.
