ok ok i know this has been discussed before i searched it up but couldnt find exactly what im looking for.. I dont mean to repost but if yall could help me id appreciate it. ok so the past week my trucks pedal will just go dead. i can put it all the way to the floor and it just wont go anywhere. i have to pump the gas a few times and finally it will kick in. a check engine light does come on and it says the code for tps or apps. i always clear it with my bullydog programmer restart the truck and its good for another few days. well recently its been happening more often maybe once a day, well it happened today and i just kept driving instead of clearing the check engine light. well the check engine light went off by itself but im still getting a dead pedal every once in awhile. why is it doing this?

The light will probably go off. Mine did this as well. Its when the slider in the apps/tps wears out and the contacts can't feel the slider touching them anymore, then it throws a code and puts the truck in limp mode so to speak. Just replace the apps/tps sensor, there about 100 bucks or so.

awesome thank you for the quick reply. tps/apps is the same sensor? thats the part that has me confused.. still new to all this and trying to understand it ALSO is there a different sensor for a automatic tranny or are they the same cause i looked at the link you put up and then did a search of mine and ended up seeing a automatic apps for 04 2500 and it was like 300 dollars.

no as far as i know they are the same sensor. I have an 04 3500 with an automatic and i used that exact sensor that i gave the link to. You might have found the one where the whole assembly comes (sensor/bracket/cables). I just replaced the sensor on mine and it worked.

Haha, yeah i am in high school and its hard to afford stuff when your paying for fuel and working part time. I remember one time i got stranded leaving the approach of my local tire shop and i had some people stuck behind me for a couple minutes until the truck decided it wanted to go again.

haha im in the same situation daily now.. but it always happens to work again when i have the pedal all the way down and then i end up black smoking all over the people behind me and they get so pissed. but they dont realize im not trying to do it on purpose. do you know where exactly the sensor is located?

Lol sounds about right hah. Here is a different video that shows it better and is shorter and more to the point. At 1:55 is where i just swapped sensors and calibrated it with the foot pedal like he does later in the vid, i didn't take those cables off or anything i don't recall.
