Evening Ya'll, 1st things 1st, THANK YOU MIKE! THIS SITE ROCKS! I've been using this as my service help for the last few weeks. I picked up a 2002 Ram 2500 SLT, Automatic, 4x4, short bed. Got what I thought was a good deal. I drove it 150 miles home, it was a DOG. I pulled 2 codes, P0112 (IAT v low) and P0237 (MAP v low). Using Mike's trouble shooting guides for the above DTC codes, after much wire tracing, ground cleaning, and testing both sensors are good along with the corresponding wiring..The ECM was bad. OK...FAST FORWARD to the 14th of March. My new (rebuilt) ECM came in, programmed ready to go. Installed the ECM, hooked up two fulled charged batteries, and proceeded to do the APP reset. Started the truck, idled well, CEL is on. Scanned the truck, these are new code that I have never had before. I got P0122 (APPS/TPS v sig. v low) and P0236 (MAP too High to Long). Again following Mikes guides, The TPS looks good. The throttle is idle or WO, no matter the position of the throttle. I monitored the APP voltage, the was a clean gradual increase, no jumping. I'm at about .560v at idle, as I press the throttle the APP voltage at the PCM #23 sweeps nicely, when the voltage hits about .83x the engine goes WO. Here the video from this morning. I look forward to the the knowledge gained. Semper Fi. Hoss
