Weird Apex issue ???

[Bauer]

I'm not sure where to start. I've never had a problem with the sled.
I've searched around but haven't found anything.

It's an 06 Mountain ~5000 miles, all stock except for clutching.

What it does is fall on it's *** after/during a climb, if, and only if, I let off the throttle even a little, it acts like I hit the kill switch, then takes off again. When it happens it looks like I'm riding a mechanical bull. Braaaa, bleh, braaa, bleh, and so on. Hilarious for riding buddies to watch. At one point, when she was really being ugly, the "cold temp" red light and the engine light "yellow" came on at the same time. I was too busy trying not to wad it up into the trees to look for a code. If I checked the codes right, it showed 22. IIRC that is the IAT.

But that doesn't add up to the problem for me. It doesn't make any sense. Then again, I'm no mechanic. I can take off and put on just about anything, if you want me to test for continuity, on a specific sensor, I go full deer in the headlights.

^^ see what I did there, I made it almost sound like I knew what I was doing.

Anyway, it seems to only happen under load. Climbing, mostly. It ran fine on the flats back to the peekup. Flogging on it and letting off didn't do anything.

Earlier in the day it took a tumble down the hill without me. I guess that is what I get for trying to be awesome.

But it ran fine for several hours after the tumble.


Any help would be awesome.

O ya. TORS has been bypassed.

Dang, nobody? Rats.

Maybe someone can help me with this.. When I check the codes. I get to 61 and it just has the #22. When I go to 62 it says there are 3 in the system.. How the heck do I find out what the other 2 are???

(should all of them show up in the display at once? Or did it just throw #22 3 times?)

In 61 just wait and it will cycle through the stored codes if there are more than one
Those had problems with the TPS sensor and that can do all kinds of things
Mode #1 is TPS setting, what numbers are you showing closed and full open
Also some had probs with the short harness between the main harness and the meter

Thanks!!

In 61 I just clicked select again thinking it would just go to the next one. I waited and it came up with 22-30-84. 30 and 84 had happened before. 30 I just leaned it oil tank up to make sure there wasn't an air pocket, and 84 was driving me nuts so I bypassed it 2 years ago. 22 is the only new one. Well, new to me.

In screen/mode 1 should it be 14-19 closed and 95-100 at WOT. Or so? I'll have to check that tomorrow, I have it all busted apart hoping that anything that may have gotten wet will dry out.

Another fun thing I found. The air box was NASTY. Standing water, and a 1/8" thick layer of oil/water goo on the inside top of the air box and other places. (this is after being in a heated garage for 2 days) It was only upside down for a few seconds. Guess I should have checked that right then and there. The vent and the drain hole were also plugged with the oil/water goo. I can't imagine what it looked like all fresh and warm.

TPS was 16-95.

I have an IAT sensor on the way just cuz. I'm hoping that it was just the oil/water goo in the air box sloshing around. It started and ran fine, no codes, so I'll just keep my fingers crossed. And stop rolling it down hills..

The TPS sounds like it's fine but check it when you are on the hill experiencing the problem
Also open it slowly and see if there is a spot in the middle where it freaks out, when they ar bad the sled run's well at WOT but not good anywhere else
The air box get's oil in it when it get's upside down while running, it doesn't really get in there from being U/D
I would go over the wire harness everywhere and look for a rub through
Delete all the codes and see if they come back

I went over the wires pretty well, I didn't see any wires that were bad. I'll check again if it continues. It was off when it was upside down. But there was a bunch of oil in there?? What gives?

I'll check the TPS again on the hill. Cleared all the codes.

Thanks for the help 0007!!!

Hey baur how ya doing? you can ck the tps on the display to see if its working correctly. thats the first thing id do. I had a issue with mine last year. If you need the sequence pm me and ill get it too you. there is a section in the tech manual on it. If you dont remember me i was the one with the sc apex you rode last yr.

Thanks MT! Are you guys going to make it out here this year? Of course I remember you. I still have dreams about your sled. Awesome. Pure Awesome.

Mine ran flawlessly this weekend. I put in a new IAT, and got rid of the oil/water goo in the airbox. It ran like it should. Never missed a beat. Not sure if it was the IAT,the goo, or some random thing got wet while hanging upside down.

I'll just try harder to keep it upright from now on.
