My 2007 Chevy Silverado was starting to almost seem like it was misfiring but I knew it wasn’t rough enough to be a misfire so I put my foot into it when it started to act up and boom I got an engine code and my truck went into limp mode so I was pretty confident what it was after an associate came out and used the scanner tool to read my engine code and boom part was in stock and I was back on the road!.
Where should the throttle sensor be mounted?
It should be mounted to your throttle body, which is on top of your engine. You should disconnect your negative battery cable before removing the sensor. This helps you avoid the risk of electrical shock or causing an error code on your engine control module.

New spark plugs and wires for the 100k 2015 Silverado. Hows the plugs look?
Step 1 – Open hood and pop off plastic engine cover
That behemoth of a top cover on your Vortec V8 is held on by only two tabs. Gently lift the front until it pops up from its post, then reach under and toward the rear of the cover to pop the back tab. (It's so easy, a US Congressman could do it!)
Step 3 – Remove air intake tubing
At each end of the intake tubing, you'll see a worm-drive clamp. Loosen both clamps at the air cleaner and TB unit. There will also be a tab at the far left side rear. Simply pop that off. Finally, unplug the sensor plug on the intake tube.
Step 4 – Remove power leads to the throttle body
Simply push down on the gray clip tab, and remove the entire plug. You should not have to remove the pink clip.
Step 5 – Remove the throttle body assembly
Using a 10mm wrench, remove the two nuts and two bolts. Then, slide the TB off the studs.
Step 6 – Inspect O-ring and replace if needed
The O-ring should be intact; however, if it has any cuts, abrasions, or is just plain grungy, you should have a new gasket in the new throttle body kit.
Step 7 – Install the new (or refurbished) throttle body
Simply line up the stud screws and slide the unit in place. Tighten the nuts and lower bolts in a crisscross pattern until tight. Do not over tighten! There is no torque spec for these, so use common sense when tightening. Plug the sensor plug in, and secure it with the gray clip.
Step 8 – Reinstall air intake assembly and cover
Install the plastic air intake tubing assembly, tighten the worm-drive clamps, and push the PCV valve back in place. Simply line up the front and rear tabs on the engine cover. Then, push down firmly until it snaps into place. Plug in the sensor at the air cleaner end of the intake.
