Accelerator petal position sensor
I have a 2002 dodge cummins automatic, every day when I get up to go to work im forced to drive 20 mph down the road until the truck warms up... Once the truck is warm it usually is on its way and I can get along down the road. Sometimes it will still run 20mph even when warm so i have to pull over and shut the tuck off for approximately 30 seconds then start it again and proceed down the road at 20mph for about 15 seconds then the power kicks in and I'm on my way even when I'm able to do the speed limit the truck still acts up I'll have to pump the pedal several times for the power to finally kick in... I cannot keep a constant speed I'm either accelerating or decelerating. Every once and awhile codes appear one was either TPPS or APPS which is the acceleration pedal position sensor I've heard there can also be a sensor out in the transmission where it goes into some mode... Please help i love my second gen and do not want to get rid of it I need to resolve this problem

If you were getting the codes for the TPS, you can try the reset procedure. If that doesn't help, get a Timbo APPS. Genos and other places have them, or you can get them from Timbo. If you do a search on here you can find the reset procedure and also info on the Timbo APPS.

An APPS code is generally an indication that it needs to be replaced. But.....always check the alternator AC voltage levels before you replace such electrical components because excessive AC voltage from the alternator will cause interference and create odd electrical problems with sensitive neighboring items.
When checking the alternator, you're looking for no more than .020 AC volts at idle and .1 at around 2000 RPM with all electronics on high. Anything outside those figures is bad and usually means a bad diode.
As for what APPS to get, TIMBO is what you normally hear people use since its much cheaper and better than OEM.
Other than that, if you have an auto then I've heard of members having issues with cold automatic transmissions acting up and doing things similar to what you're describing.
