Moparman, I finally had some time today to further investigate the spliced wires on my APPs sensor. The first was with. The blue/green splice to a ground. The second is the blue/white going to pin 23 of the PCM. I disconnected both splices and now my wait to start light flashes and the truck wont start. Does this mean I have a bad ECM and was the blue/white splice a workaround? I should mention that the originally wiring is intact. Thanks, Chris Out of curiosity, I reattached the splice going to the ground and my WTS light stopped flashing and the truck started. I've left the splice to the PCM unhooked for now. Chris

Today's code is P0121 - TPS A circuit range/performance. Thanks

Jwirth thank you for the advice. In another effort in futility, I disconnected the batteries for 2.5 hours today, then reset the apps module after hooking them back up. To my dismay, the truck went into dead pedal less than 2 blocks from the house. Argh! BTW, I've cleaned every grounding point. I guess it's back to tracing wires.

Hello All, I wanted to jump into this thread because I'm experiencing a dead throttle pedal issue as well. I've replaced the apps with both a Timbo and Wells and no luck. I had Mechman build me a new alternator thinking that I was getting high AC levels, no luck. For some reason, the previous owner installed a jumper from the #3 pin on the apps to the 23 pin on the ECM - orange/black wire (data link/fuel inj) . I'm not following this logic. I drive the truck on Friday 150 miles without a problem but, yesterday I had a dead pedal 7 times in 5 miles. Ready to sell if I cant get it figured out. Thanks for the help, Chris
