So my family and I are planning a Colorado jeep trip in august and had the jeep put in the shop (a small auto shop in town) to have the brakes checked and a tmps malfunction looked at. Well while researching the TPMS issue they found codes showing that my throttle body had lost connection with my pedal afew times. He said that if this is true, I could lose the ability to accelerate while driving and be stranded somewhere. 500 bucks parts and labor because you have to replace throttle body assembly and gas pedal.

Is this total BS or is it something I should actually have done. I have the money to pay for it but thatll put a big damper on our vacation.

Anyone have experience with this?

 

Never heard of this. Unless you've actually noticed the problem though, I'd say you're ok for now. If it's not actually throwing the code to the dash, it could be a fluke and may never happen again. I've had a similar experience myself. Chrysler sets those OBD sensor thresholds for a reason.

Sounds like you made the right choice. If you notice it throwing codes or feel the problem while driving, you know it's a problem. Even then, replacing both the throttle body AND pedal assembly at the same time sounds like major overkill. Blind fire. For all these guys know, it could be a simple wiring connection that came a little loose.

Check the connection on the harness at the throttle body, I guess.

 

thats what I was thinking as well, a real problem would show up on the dash board. thanks for your input

 

Haha. Right after posting this I went to meet my brother for some drinks - he's worked as a mechanic at a few dealerships and is now working for a small shop here in SD - I asked him what his shop would do and he said:

"Well, it depends on which mechanic you ask. That guy over there (points) would say 'gotta replace it all' because he's too lazy to diagnose the problem and would slap you with a huge bill without blinking an eye. Then you drive away with a new throttle body and pedal but, SURPRISE - didn't actually fix anything"

...

"While that guy (points) emphasizes maintaining good customer relationships over big dollar repair jobs and would take the extra 20 minutes to figure out the REAL problem and save his customers a few hundred dollars, guaranteeing they come back for more work in the future"


Such a shady industry.

 

Not sure they have to be changed as a pair. My Pro Cal unit has a function to sync the throttle body and gas peddle.

 

Might just need a dealership flash. Doesn't sound like a real problem.

 

Hi all

I hope trip went fine............................BUT mechanic may have been right ......................why.................??


a lot of jeepers dont realize that the throttle position sensor built into the trhottle body is a resistive sensor, over time it wears out over the spot where it sits in normal idle, you check it and it looks normal, till it barely looses contact and you get that glicth or roughness, scanner wont see it as it is to long on time interval between scans, only way to pick up is with ociliscope.( dealer has this) any vehicle jeep or car that has over 100km should really have TPS sensor replaced, but since jeep maintians that it is a module, they make you buy the whole thing..........................hopefully someone will take one apart and figure out cheaper solution, if you have a warranty dont worry take it to dealer.


Sometimes dealer may be right (yipes!!) it does wear out especially over 100km and wont throw codes, as time interval on obd2 scanner is to long to pick up, need more specialize equipement to pick up.


I am going thru this now, try to find cheaper solution.......................................... .
