I have a 2004 dodge late model. Right after I bought it the TPS went bad so i replaced it and it fixed it for 2 months maybe. I have cleaned every ground I can find on dang thing also. After you drive the truck on a good drive (like 200 miles) it will go into limp mode and throw at least 12 codes. It throughs every code twice to for some stupid reason. They are like tps sensor, turbo, fuel rail pressure, camshaft position sensor, and so on. sometimes it throws up to 20 codes. the computer on the side of the motor had salvage writing on it so it has been replaced before i bought the truck so i though maybe it was bad. I found a used computer and bought it and put it on. It was a pull off computer that has a reconditoned sticker on it.(but it had been used after the recondition) Well it didnt fix the problem either. i didnt get the computer reprogrammed at the dealership or anything but everything worked. I was impressed. I dont know if its bad too or what but dodge wants 2 grand for a new one. But like i say it only does it after it gets good and hot. the truck does not have a chip or anything on it. And i dont believe it has ever had one. The manifold hasnt been tapped or anything. It has the fuel pump in the tank already. 160,000 miles. no white smoke or anything. It goes into limp mode when it does it though so its not a good deal. it sucks when your a couple of states away. sometimes it will die or just sit there and cut out really bad. but after you let it sit there a while it will start and run fine. I carry a scanner in it and sometimes it will delete the codes and fix it and other times it wont delete them. ive had a scanner at a dodge dealership on it and they didnt know anything more than me. i really dont know what do. Maybe a big cliff is in order. i would really appreciate any help. tyler.

 

Have the dealer reprogram the other ECM with the options on your truck. Can't take an ECM off one and put it on another. Be cheaper than a new ECM, IF it works.

 

Hello,
You cannot just put another unit in without programing it. Also the number has to match if not the will not work. I purchased mine here was programed and ready to go Auto Computer Exchange - Auto Computer Superstore - Cheaper than dealers and mechanics.
I talked to a guy name G he helped me out.

Hope this help

 

thanks a million guys. it worked all but the windows wouldn't roll down and the ABS light was on. but it needed to be programmed. i put the old computer back on it now.
