I cant tell u what will fix it U saw the possible cause that I listed above I am not standing infront of the car with a scanner to tell u or I would get it done. What I am telling u what wont fix it and thus far nothing U has said will take it to an experienced Chrysler driveablity guy for this code unless U have deep pockets and can throw any and all parts at it.

Okay... here's the latest scoop...

I was told to take the car to our local Chrysler dealer.

There was a TSB put out about "erroneous codes"...

Here's the TSB # 18-031-02

My "erroneous code" is P0152. The dealership is going
to do a reprogram on the PCM and this is "supposed"
to fix the problem.

What do ya think?

By the way... all this work is costing me nothing.

Thanks,

At what point are u gonna listen to what I am saying this tsb will not fix your issue

I dont see a p300 nor a p175 on there do u??
this flash is for 02 sensors issue U dont have that U have a fuel system rich the list I gave u are the possible causes for what your car is doing a trained tech that knows about Chrysler cars will know what to look for.
If u flash the computer all the valuable data that will help find this issue will be lost.

also one more thing do u have a 3.5 or a 2.7 engine?

My engine is the 3.5.

UPDATE: New Engine... Same Codes!
 

Hello there.

After months of fooling around with the codes
that were being thrown... (P300, P152, etc..)
the dealer put a new(used) 3.5 engine with 70,000
miles on it in my 2002 Chrysler Concorde Limited.

After installing the engine, the car STILL threw
a P300 code...LOL

These "techs" have replaced sensors of ALL TYPES
and are now saying the car runs great it's probably
a problem with the computer itself.

Any thoughts?

Thanks,
G
