1999 GMC Sierra 2500 V8 5.3L 8th Vin Digit T Throttle Position Sensor TRQ ESA94902

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Replace the TPS sensor, throttle position sensor, which is located right here on the throttle body. Going to unclip the electrical connector, pull it out, and put that aside.

There are two T20 torque screws on either side of this. You need to remove those. A little tricky to get in here. It's taking a longer extension and it's not quite straight on but it should work, because the coolant hose is a little bit soft. I can squish down into it. Ratchet in here. Reach in and grab it with my fingers so I don't drop it. Pull it out. It's a little screw. I'll put that aside so I don't lose it. Got a different linked extension.

I'm trying to get to the bolt that's underneath. Now that it's loose I just pull it out with my fingertips and put that aside. Without the screws connecting it, with the harness out of the way, I grab the sensor. That should come right out of the throttle body. There it is. It does have a key way to it. We'll make sure when we install the new one, it goes on the same way.

Here's your original throttle position sensor or TPS sensor from our vehicle. This is our brand new one from 1AAuto.com. It's an exact match. The same little key way in here. New little O ring seal, two bolt holes, same style connector, so it'll fit great and take care of any throttle position sensor problems you're having.

While we're installing this, be sure we line up that flat key way with the flat key way on this part here of the throttle body in here. Align it back up. Sit right in the same spot. Install this upper screw. Install the lower screw. Start the threads by just my fingers and then I can switch to the torques bit and ratchet. It's just a very small bolt going into aluminum, so as soon as I feel it get tight I'm just going to stop. Sneak the ratchet and socket into here. The bottom one. Once I feel it get tight I'm just going to stop. Reinstall the electrical connector. Push it in. It'll click. The TPS sensor is replaced.

Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace the throttle position sensor on this 2002 Chevy Suburban with the V8 5.3 liter engine. The items you'll need for this includes a 10mm and 15mm socket, a ratchet, a flat blade screw driver, a pair of pliers, a pry bar, a T20 Torx driver, an 8mm wrench, and a hammer.

To start off, you want to disconnect your negative battery cable. Use your 8mm wrench and just loosen that up. Then it just pulls free. Set it aside. Next, you want to loosen up this hose clamp right here. Then loosen up the hose clamp right over here. Now, you can pull this intake hose forward and pry this part free. Lift it up. Now, using your pair of pliers, just push the clip, disconnect that lower hose, and set this intake aside. Using a 15mm socket and ratchet put it on the tensioner, pull the tensioner up, and pull that belt off your alternator. Then, carefully release the tension on the ratchet.

Pry up this tab and disconnect your alternator harness. Then pull back this rubber boot and remove this 10mm nut. That wire just pulls free. Now remove these two 15mm bolts. We'll fast-forward as Don does that. Using your pry bar, just pry the alternator up and out. Once you do one side, just repeat the process on the other side of the alternator. Now, pull back on this tab and disconnect your harness, and then remove these two T20 bolts. We'll just fast-forward as Don does this. Now, the sensor will just pull free.

Take your new sensor and push it into place and replace those two T20 screws. We'll fast-forward as Don tightens those up. Then reconnect your harness. Put your alternator back down into place and then pry it until you can line up those holes. Then push your first bolt in. The first one's going to be a little more difficult than the second one will be, because you're still trying to line everything up. Just use a hammer to help knock that bolt in. Once you get it to about this point right here, you're all set. The second bolt's going to be a lot easier to put in. Now, we'll just fast-forward as Don tightens those up with the 15mm socket and ratchet.

Reconnect the harness to your alternator. Put this wire back into place, and replace that 10mm nut. Then put that boot back over it. Again, use your 15mm socket and ratchet on the tensioner, and then pull your belt back up and on to the alternator. Now, take this upper intake assembly, push it back down into place, and push it back onto the engine. Re-clip that lower hose, then reconnect this hose, and tighten up those 2 hose clamps. Now replace your negative battery cable and tighten it up with your 8mm wrench, and you're all set.

In this video, we're going to be working with our 1996 GMC Sierra. We're gonna show you how to remove and replace your vehicle's throttle position sensor or TPS on a 5.7 liter V8.

If you need parts for your truck, you can follow the link down in the description of the 1AAuto.com.

Here are the items you'll need for this repair.

Remove the thumbscrew on the top of the intake tract at the throttle body. This can be done by hand or, if yours is stuck, you can lightly grab it with a pair of pliers and rotate it that way. Disconnect the rubber elbow on your PCV breather and loosen this hose clamp with a flat blade screwdriver. Now, you could disconnect the electrical connectors, undo the airbox, and remove this all as one piece, if you want, depending on what you're trying to get room for. However, this is all that's necessary for what we are trying to do. Undo the boot, lift up and forward, and remove the upper intake.

Your throttle position sensor is located, you can see down the end of the throttle blade here, there's this rod that goes to the middle and that attaches here. The other end is where your cables are. This senses the angle or position of your throttle body. To remove it, we'll disconnect the electrical connector and remove the two T25 Torx bolts with a Torx socket and a ratchet. These are very small, really don't want to put a lot of force on them. They should just come right out. It's important to make sure your Torx is seated fully into the head of the bolt. If it only goes in partway or there's dirt or rust built up in there, you're going to round it off and it's going to be pretty difficult to remove. Once the bolts are out, carefully remove your sensor.

You'll see that it's keyed there and it's a keyed shaft that it sits on, too. To reinstall your throttle position sensor, line up that keyed slot, pop it into place and reinstall your two T25 Torx bolts. Reconnect the electrical connector.

Reinstall the intake tube by hooking the tab over the front of the throttle body and setting the back into place. Reinstall the thumb screw onto the stud, reinstall the tube into the filter as well as locking it into the back of the air box. Reconnect your mass air flow and intake air temp sensors. Drop the lid back into place. Secure the tabs, install the breather line and you're good to go.

In this video, we're going to show you how to replace the throttle position sensor in this 2002 GM Sierra 2500HD. This particular part is similar in a large variety of GM models, and the only tools you will need for this is a flat blade screwdriver, T20 torx driver, and a 15 mm socket and ratchet. To get to this, we're going to need to remove a couple of things. We'll start off by removing the air intake hose. You just want to use a flat blade screwdriver to loosen this bolt, and then that'll loosen the clip, and you can pull this right off. You just want to set that aside.

Next what you want to do is you want to get a ratchet onto that, which is the tensioner, and then you want to push that back, that'll loosen up your serpentine belt and you can pull it off of the alternator. Now there's two bolts that secure the alternator, and we'll fast forward as he removes the one on the left side. This bolt on the right, we're just going to loosen up.

Now, using a flat blade screwdriver just pry up the alternator and this will give you access to the throttle position sensor, right there. It's held in with two bolts. You just want to disconnect the connector here by pulling back on that tab, and we'll fast forward here as he just removes those two T20 torx bolts that secure the throttle position sensor.

Then, you just want to remove the sensor. It's the old throttle position sensor on the left, the new one on the right from 1A Auto. They're identical. You just want to line up the sensor. As you can see, you just push it into place and then you want to re-insert those T20 torx bolts. He tightens them first by hand and then he uses the driver to tighten the rest of the way. We'll fast forward as he tightens these up.

Reconnect to your sensor by pushing that clip back into place. You want to push your wires out of the way and push the alternator back down. Then, you can see he uses a flat blade screwdriver to just pry that back into position, line up the holes so you can re-insert the bolt. Then you want to re-insert that bolt and tighten it all the way up. We'll fast forward as he tightens this bolt. Then tighten the other bolt.
Now you just want to put your serpentine belt back into place. You want to put the ratchet back onto the tensioner, push it down, and that will allow you to get the serpentine belt back onto the alternator. Then you want to re-connect that air intake, just push it into place. Then using a flat blade screwdriver, tighten up that clip and then you are all set.
