Alright, so I have a 2003 2.0L SXT. Nothing fancy done to it. Bone stock. Awhile ago I had the solenoid go out, and take the ECM/PCM with it one day while driving, the car lurched and suspended the car into limp mode. (Ouch yeah I know) Well after having both the solenoid pack and the ECM/PCM replaced I'm still getting these two codes. And, when I decelerate my car will lurched right before I come to a complete stop. I have my transmission fluid replaced, along with the filter. Can anyone offer any insight as to what to look at next? I already spent a pretty penny on the new ECM and solenoid pack..

Thanks so much!

 

bump please

 

No need to bump after less than an hour. Once a day is plenty fine.

Since you have a new solenoid pack and PCM, I'd go over the wires to the solenoid pack as a start. I'm sure you've already looked for a leak? These are the possible causes of a P0841 code, with the items in blue I'd look at first:

• If code P0944 is present, ignore code P0841 and perform code P0944 diagnostic procedures
  
• LR pressure switch sense circuit, open or shorted to ground between PCM and solenoid pack
• LR pressure switch sense circuit shorted to battery
• Solenoid/Pressure Switch assembly
• Valve body - solenoid switch valve stuck in LU position. May be accompanied by a code P1775.
• Loose valve body bolts
• Plugged filter - internal transmission or torque converter failure
• PCM

 

What should I be looking for when giving these wires a look over, because when I installed the PCM everything looked fine..

Edit: Also, which cords correlate to the pressure switch? My fluid levels were fine when I had the fluid replaced, I just wanted to replace them and the filter to be certain that wasn't the issue.

 

You should be looking for a wire that is broken or one that is missing sheathing that would allow the actual strands of wire to be possibly grounding out.

P0841 is the DTC for the LR Pressure Switch Sense Circuit. The LR pressure switch wire color is dark green. That should be your main focus, but certainly check all 8 wires of the solenoid while you are looking at the one.

 

If it is one of the wires, how difficult is it to repair/replace?

And how could the wiring be affected the driveability? By sending incorrect readings?

 

Likely, it would be as simple as cutting out the bad piece and splicing in new wire.
If the wire is broken, there will be no way at all for the computer to "communicate" with the LR pressure switch. If it is randomly grounding out, the pressure switch will either be unable to communicate at all, or it will be communicating incorrectly resulting in things such as stumbling or jumping because there is only a partially correct communication between the switch and PCM.

 

Thanks I'm going to have to take a look at it soon and ill let you know the diagnosis

 

Update! I went to take a look at the wires, with some electronics cleaner spray. Sprays down all the plugs and connections. cleaned that area up some. HOWEVER now the plug wont plug back into the PCM because the plastic clips are dry rotted. Just my luck. I had to jerry rig them back into place. And after looking for the wires and checking for breaks and tears they all look great. I think I would need a schematic to search for all the grounds..

Any tips on how to get those plugs to stick and stay back into the PCM without buying new ones? And, how many grounds are there, I could spend forever trying to find all the grounds.

I also found this cord just hanging around during my investigation, it was up near the brake fluid reservoir and battery. Any insight as to what it is? http://i48.tinypic.com/2w39u2v.jpg

 

Battery temperature sensor. Belongs on the battery blanket. Is your battery light on? Dodge wiring diagram is located in the link in my signature.
