this technology needs a lot of improvement yet.

recently my car stops responding to throttle command and light in the dashboard lit
|~|

the good thing here is that the car went into LIMP mode and i can drive it back to home safely that day.


I suspected something wrong was on the throttle body and i proceed to disasemble it, after some tests (find out that it doesn't open and made clicking sounds) and research on dodge forums. so i went to buy it and replaced it.

here is the outcome

removed the bad TB, does not have any brand of it.. it just has BW on it. (borg-warner) maybe?

Image

then i broke it to open as there are no screws

once open i saw what the damage is.. worn teeth on the gears used for open/close the plate

Image


Image


finally i discover something interesting.. it has a Hella circuit board... interesting mix of components for an "American" car

Image


after buying it from the dealer (around 200 usd + tax) and a scanner i get from AZ to clear codes. it is running like a charm.

car is 07 model 1.8L engine, manual trans passed 100,000 km mark

When you said you broke it open, did you damage it enough that it would never go back together?
(looking over at the soldering iron and scope)... Maybe I shouldn't be thinking what I am thinking.

On the up side, shave 0.001 seconds off the response time, will make the butt dyno happy. Would love to see the stealership void my warranty on this type of mod.

To the OP, have you had anything else go funny with your car?

well not until this.. what i had noticed after replacing that part is it that engine started right away at the first time when left parked in intense sunshine. (not a problem when is cold or parked in the shade)

before i had to crank 2 times.. the dealership always toldme that it went away after tune ups. which in fact did but the issue re-appears after some weeks.

everything else on the car is fine.

the part is sealed (id say "canned") so is not going to keep moisture off if resealed, and will be noticeable by your dealer.

Nice review of your issue! Thanks!

I wonder... can anyone confirm whether the 1.8 and 2.4 in-fact do not use the same TB? This would be another thing I wouldn't want to have happen at 11pm on a Sunday night in the middle of nowhere...

thats pretty intense that the gears were destroyed

I will say, i do hate how EVERYTHING on this car is controlled by a computer

Yea, drive by wire is nice, and blah blah blah, but all it takes is a problem with the computer to leave you stranded

x2 on the hating everything computerized.

I do have to ask, how can driving by wire be nice?
I miss feeling what my thottle is doing. I my wife's old done up neon, you could feel any change in the clutch and the thottle.
I also hate the fact that I am suggesting something to the computer.

lol, theres not much benefit to it, ill give you that

its one less wire under the hood? :rofl:

My old car, the throttle cable actually wore out, stretched out, whatever lol, and i had to replace it

Compared to my old car, the throttle seems smoother, but thats comparing ford non drive by wire to a dodge drive by wire, so apples to oranges :rofl:

Throttle Body

I have a feeling that this is causing my recurring problems... no throttle response on and off...now going on 118,000 km and been to dealership at least 5 times with no improvement. I'll be mentioning this possible fix next time I'm in !!!

@mraguilar- I was wondering if you could post pics as to how to remove the throttle body. I can't seem to find it on my car. Thanks

It has 2 screws and it can be either removed from above , you have to remove airbox, pipes , clamps and some sensor wires. and of course the connector of the TB itself.

you can remove as well from below the car if you have ramp or a pit. i think is easier.

Mine is getting replaced right now at the dealership. My service guy got it fixed for free under the emissions warranty which is up to 50,000 miles. I just bought the car 6 days ago and I have 43,000.

I wanted you to know that this post is the reason I joined. I always get Googled to this site when looking up issues for my 2.4L Caliber R/T. But I had to join to thank you and let you know how much this helped me understand the missing link in the intermittent behavior I was dealing with.
HATS OFF TO YOU FOR BREAKING IT APART!
I plan to do the same with mine to see if I am right in that I have the same problem.
Also I have a friend with a Avenger doing the same thing!

So thank you for this post!

i just took my 2010 caliber 4 cylinder, to the dealership and they want $629.00 just to make in run :( they said my throttle body is sticking and would replace just that for $498. i do not have that kind of money and found many parts for around 200 or less. however im worried with all the technology in this stupid thing i wont be able to rest a code or something and it wont run. any details about how i get around that would be much appreciated.

Most of that will be labor. It should cost about $180 and can be changed yourself from under the car. Check out wermopar.com.

get this, the dealer put the throttle body in and now my car wont move. they told me they are waiting on Chrysler to make a decision on what to do now.Either give them software to download because the car wont except the new part or try a different throttle body. :notallthere:
