aaps sensor

Ok just got back from my buddies house installed new IP and lift pump started it up and it ran just like it did before. It Idles fine but when you give it the gas it just runs rough. No accelleration or power. The cruise control light blinks on and off randomly and the temp gauge goes crazy. I mentioned this in an earlier post. Anyway we pulled the codes. I know we should have done that first (long story). These are the codes we got.
PCU p0122, p0500, p1693.
ECU p0121, p0230, p1689, p0217, p1488, p0575, p0562, po237.
Not sure what to do next. From looking up the codes could be Apps or ecm. Any other suggestions or thoughts would really be appreciated. I actually have the same truck 2002 6 speed HO stock except mine is 4wd and his 2wd. Would it be advisable to put my APPS sensor on his truck just to see if it made a difference. I don't mind doing it to help him out but after seeing how much they cost (595.00) just don't want to screw mine up. Any help would be greatly appreciated. I feel bad for him cause he just laid out 1500.00 for the IP and LP and his truck is still messed up.
Thanks for your help in advance
Rob

POSSIBLE CAUSES


DTC detected in the PCM


First if you have mods, remove, clear codes and run. if they go away, put mods back on one by one and see if any set the codes off. The bad thing here is when mine did it it was a bad ECM, and every symptom leads to a bad ECM. I have seen it work to clear codes. So try this first, but I would have to say it sounds like a bad computer. They can be rebuilt or buy a reman.

Thanks Hin
Sorry so late getting back. BUSY!!! Anyway he ordered an apps sensor from Mopars source timbomb I think. But will get onto checking the computer. I think I saw on mopars or somwhere in all my searches about testing the apps sensor. Will look for that. Is there away to check the computer for good or bad ? On the codes. His truck is completely stock. Is there away to clear the codes and start over ? When you get a code when you fix the problem is it erased or does it stay ? Sorry that sounds dumb but was just wondering how that works.
Thanks Rob

It will not go away right away. It may take a few cycles, but unfortunatly it will effect the way it runs. check out bule chip diesel for the apps. it is way cheaper and way better.

Don't bother with the APPS... Look at you codes... You got a mess of low volt codes that are not making sense...

ECM is on the way out... I've seen this before...

Thanks to both of you for your replies. While I am sure this is not what he wants to hear at least we are getting closer to getting it fixed. Next question I guess is where the best place to get a replacement ecm at a good price ?
Thank you Rob
