There was a service bulletin out for the wiring harness on the 2011 800 xp's. I had to take mine in for it.

 

You would think that after 3 trips to the dealer they would have mentioned that. How can I get info on that service bulletin to take to my dealer?

 

My dealer said that the service bulletin expired. All that means now is that you have to pay for the repair. They should still know about the bulletin just tell them to check the tps, Tbap for broke wires.

 

Any ideas about the adjustment screw that was adjusted? Can it be set back to factory specs?

 

Idle problems

My 2011XP idle problem is caused by the tbap wiring harness shorting/breaking. Once the tbap wiring breaks, the engine runs rough, registers multiple engine codes and creates intermittent idle problems often making it impossible to shift until i turn off the engine, shift and re- start. The last time i had a tbap failure the engine just would not start period. The next day, it stated up, but would then die. No mystery, essentially the tbap wiring is essential to smooth/dependable engine operation.

The last repair was a new harness and a slight re-work of how the harness is routed over the engine. I am on my third harness. There is an after market tbap harness available. However, I have not tried that yet. The problem I have seems to be linked to the effect of normal engine vibration on the delicate tbap wiring traveling over the top of the engine.

This the only electrical issue I have had with the machine. Hope this helps.

 

Thanks guys! I will give this a try this weekend and post my findings.

 

Sounds like what mine is doing too. 2011 800 also. The dealer changed the IAC and wires to it but it still acts up! The dealer is to cheap to change the harness on the TPS and T-MAP sensors under the extended warranty. Let me know if you find the culprit. Or I'll let you know if I have any luck

Ranger is at the dealership....I will post an update once I hear back from them. I did order the after market tbap harness from OTB Powersports (I am sure I will need it eventually!)

Put this harness on my 2011 and havent had any issues since. Its a MUCH better built harnes and plug then the stock ones. The Oem wiring in the polaris harness is to small wiring and breaks due to the vibration.

 

I just ordered the OTB harness. How difficult is to install? Any suggestions? Thank you.

Not hard at all. Just follow the instructions it comes with to cross referance the wire colors and once you crimp them together you just plug it in. Probably about a 10-15 minute job.

 

Thanks, Honda.

 

Update:

My Dealer replaced the wiring and the plug going to the TPS. I was able to locate this as being an issue by wiggling the wires near the plug (thanks to great advice from this forum!!). I was able to show my dealer that this was causing the ranger to idle up and down. I have not installed the aftermarket tpab harness yet but I do intend to soon. I am taking the ranger for a long test ride this weekend to see if the tps wiring repairs corrected my issue.

Thanks to everyone for their help! I will post the test results after the weekend.

 

Gaducks, did the new harness fix your problem?

 

After much use this weekend it seems that the problem has been corrected for now. I still plan to change out the tpab wires once the aftermarket part comes in.

 

Harness arrived. Will try to install it this weekend.
