Tried Everything, Then FIXED P1516 Throttle Position Sensor Code 2003 Chevy Silverado 

You’ll get another 250k out of the country strong 💪 Chevy 👍

Body earth are common on all vehicles the more they are in a rust belt the worse they are ,replacing earth links to the body is Good 👍 Engines relying on earth throughout the vehicle,bad Earth's will burn out sensitive part's like injectors to coils.

My 2005 Mustang GT had a bad throttle sensor. Man, drove me nuts for a few days. Finally had to swap it out for a new part in an Autozone parking lot. Then proceeded to drive 1000 miles to Tn in 12hrs. 😂😂

Carry your code reader with you and clear the codes till you get where your going

Still running good?

Joey said to say Donnie..its broke

going thru this right now with my 2002 escalade i changed the tps still went into limp mode changed the whole throttle body it worked for a day then back in limp mode… i would have to pull over clear the code and it’ll drive fine my mechanic can’t find out why it’s doing it

👍👍👍
