heinzbean Hi Sam
Im glad I spotted this post because my mil light was permanently on . Manual 6 speed only 5k miles. There was no code. The dealer just reset the computer and didn't really know why the light had come on .The mil light and a loud chime.
After reading your post i have discovered that When I start the jeep there must be a sensor at the top of the clutch travel (which lets the engine start). There must be another sensor at the bottom of the clutch travel (which tells the computer you have engaged the clutch properly). I was previously starting the jeep by just engaging the clutch enough to start the engine.
So far so good. No stupid mil light. And why no mention of this in the jeep manual.

Throwout bearing resides in the fork, and (this is where I'm fuzzy) doesn't touch the splines in the pressure plate until the clutch is engaged. Touching the clutch peddle and feeling where the loose slop stops, and you can start to push against the retract spring for the fork should do absolutely nothing.

Yes, once the spring and fork start to move, yes.
Resting on the spring and not moving it should be zero wear.
You are definitely correct if we're talking about very light pressure on the pedal. But if people are throwing CELs, i suspect they're moving the TOB. The throwout bearing on my nissan has virtually 0 clearance before it starts pressing on the retaining springs. I haven't seen the jeep trans apart, but it does feel like the action occurs with very little pressure.

I sure hope this doesn't trigger the sensor, but I think it might.

As long as you're past the friction point of the clutch, you're not going to hurt it. You probably don't want to sit at a light and half clutch while waiting, but you shouldn't hold the clutch in at lights anyway for fear of destroying the throw out bearing.

This. There have been situations where drivers rest their foot on the clutch and get the light. You mentioned that you have done that, probably the reason for the light. And, some do rest their foot on the clutch even though it should never be done. Why, who knows. Why do some seniors rest their foot on the brake. I've seen that too.

I couldn't say why, but I know of a lot of people that do, and I've been behind people who must rest their left foot on the brake too. I once followed a car through town and the brake lights were on almost the entire way.

LMT Rubi OP, I have a 2013 JKR 6 speed with less than 2000 miles and my TOB is fried. i am getting a new clutch next week. Prior to all this, I had the same code noted above, show up twice. Dealer techs were useless and couldnt find the reason the codes were coming on so they just cleared them and sent me on my way

If I had to guess, this is the problem.

Caveman1965 For around a hundred dollars you can get an OBD2 code reader. It plugs in under the dash and it will tell you what the fault code is and allow you to clear the code and shut off your check engine light. More importantly, you'll go to the dealer with an important advantage. You'll know why the check engine light came on in the first place. Your dealerships explaination soulds a little fishy to me. I'd want to see that code for myself. Good luck.

Holy Crap!

Well I expected a reply but maybe next september or something. Thanks so much for the input!

The dealer is Wickstrom in Barrington Il. I have known them for a long time and they have always been very good. They told me that the sensor in the pedal indicated I was not depressing the pedal all the way.

I thought about what you said about resting my foot on the pedal and I will have to say I did find myself doing that once or twice. I never heard the engine racing or anything while driving but I did think just the way my foot rests on the ground that may have happened.

Maybe that sensor works both ways, either all the way in or not all the way out.

Either way I think I found a nice place to talk Jeep

Thanks alot,
Sam

Ask for the fault code and research it.

With as many careless and speed shifts that occur daily in many '12-'13 model year Jeep Wranglers, equipped with manual transmissions; this board would be awash with idiot light questions if this were the case.

Creepin__Jeeper I have over 10K miles on my 12 JKU 6 spd I would estimate that for the first few thousand miles I pressed the clutch all the way down until I eventually I realized I could basically half clutch it and get smoother shifts I have never had any check engine lights so I dont think it has anything to do with that.

I'm curious about what your dealer has told you... are they indicating that in one way or another there is a sensor in the trans or maybe on the clutch pedal that can "monitor" the travel of the clutch? I call BS on that explanation from them since I know I half clutch and I'm sure many others out there with the manual trans do also and I've never heard of this.

I will add that with this clutch it doesn't seem that you need much pressure on the pedal in order to make it disengage or "slip" so do be careful to not rest your foot on the pedal...

Stick shift and check engine light.

Hello,

I will start by saying I am new to this forum and appreciate all input.

I have had 3 Jeeps in my life, the first a 85 CJ7. I loved that car but boy was it a pain, so many problems I can't count. I owned it from 87 until about 92 and had to get rid of it. Next was a 99 Wrangler sport and it never gave me a problem over 2 years. Both of these where stick shift as have been all my cars over my life time. Some include a 94 Honda Accord, 96 BMW M-3, 04 BMW 330, 07 BMW 335 and a 09 BMW 335.

I say this because I have been driving stick shift cars my entire life and have always enoyed A real Jeep and have had them in my car mix over the years.

I purchased a 2013 Wrangler Sahara and almost right off the bat my check engine light came on. I took it to the dealer and they tell me I am not pushing the clutch all the way down. Has anyone had this problem? I can't fnd anything on it but will say in all my years I have never had a problem and never worn out a clutch. As far as I can say you do not have to hit the fire wall to engage the clutch.

Is this a real problem or do I have to live with the check engine light going forward?

Any help or thoughts are appreciated and thank you.

Sam
