guys im at a loss and literally tried every dang thing... so i have a 2015 nissan titan several mods including a 102mm intake manifold TB LT headers so on and so forth so ive had these mods for YEARS with zero issues so im confident its not mod related but however my cruise control doesnt work and neither does my throttle. ive replaced the tb with a new updated version and the pedal itself is brand new. the ecm is throwing the code P1564 when it lets me clear this code ill gain partial throttle control for a few seconds and then it throws the code again. Im going to change the trans speed sensor thats in the trans but guys please i need help!!!! someone has had too have had this issue with a helpful solution

Your 2015 Titan is a different truck than the 2016-up Titan XD.

That being said, you probably won't find answers here and would likely do better on a site dedicated to the first generation standard Titan.
