Don't Race Me
 

Hello Fellow Jeepsters,

Warm weather is upon us (at least in New England) and the new tight-as-
a-drum soft top is gently billowing!

If you may remember, I had a PS pump replaced a few short weeks ago,
and upon pickup noticed the check engine light was on, followed by
high revving startups, almost conking out gas pedal taps, and
stuttering on heavy acceleration. I figured the TPS got fouled out
from the engine washdown and cleaned the contacts with cleaner as I
read Mr. Romaine (sp?) suggest countless times here before. In
addition, the mechanic suggested new plugs, wires, rotor, etc... and I
took the advice yet nothing changed.

Now it seems to take a while to fire up on starting, just cranking for
what seems like forever (3 or 4 seconds)...but the time is getting
longer as each day passes, and heavy acceleration is a joke. High revs
on startup are intermittent as well as the near-conkout when the gas
pedal is goosed - some days it's fine, others it's bad. It also seems
to miss a beat every-so-often while at idle.

I did the ignition code trick and it's saying 24 (12, 24, 33, 55).

12 - recently unhooked battery to install cd player
24 - TPS voltage
33 - no AC (AC?! in a Jeep Wrangler?!?! hahahaha!!!)
55 - blinking lightshow is over

Will a new TPS really clear this up? I would go and get one right away
if it weren't the darn-tootin' cash flow issue. Money is a little
tight to drop $50 (at NAPA) on a new TPS... so really - how accurate
are these codes? I did purchase STP Throttle Body Cleaner and plan on
doing it this weekend - does the part need to be removed? Or can I
blast the crap out of it right there?


All the best, and thanks in advance,

~Jon

Re: Don't Race Me
 

So do you have a YJ or a Jeepster?

There are very few 'Jeepsters' on this group and I highly doubt they
would have any idea about a modern FI engine screwing up unless they
have modified their rigs.

I am not a Jeepster owner, but I do know what the voltage readings
'should' be on a 4.0 engine.

With the engine off and the AC off and the key in run, you back probe
the TPS plug with a multimeter to read the voltage levels. The two
wires for engine control will read 200 mv at the idle position and 4.8V
at the wide open throttle position with a smooth rise. The other wire
for the tranny shifter will read opposite to that or 4.8 at idle.

This code will always come up.

This can cause poor starting and rough running.

I can't explain why this would come on.

I'd not second guess the codes. The trouble you have is that you don't
really know how long those codes have been stored. I suggest you clear them,
then look again in a week or so and see if any of them have come back. You
should expect to see 12 and 55, any others (especially those that repeat
from this list) are codes that need your attention.

Do you think it might be because he 'has' no AC.....?

Re: Don't Race Me
 

I would not expect an option that is not installed to throw a code.

Maybe I give the engineers too much credit to write firmware that is able to
understand what is installed or not, and only issue codes for failures of
installed systems.

Re: Don't Race Me
 

I would not expect an option that is not installed to throw a code.

Maybe I give the engineers too much credit to write firmware that is able to
understand what is installed or not, and only issue codes for failures of
installed systems.

Re: Don't Race Me
 

Yup, you give them too much credit for sure.

The Jeep computers 'always' throw an AC code if you don't have it, I was
being funny, hence the wink, ;-)....

Well, alright then.

TO THE OP,
Do not attempt to troubleshoot the code about the lack of AC, it's supposed
to be there.

Re: Don't Race Me
 

Aye!!

By "Jeepster's", I was alluding to "Jeep Enthusiasts". I will learn
the proper terminology next time! ;)

Thanks for the heads-up on the meter readings. I will give that a try
tonight when I get back to the house.

I indeed DO NOT have AC.

Thanks for the insight everyone! You guys have class, and your time
spent helping out noobies is admirable!
