Hi, I'm Mike from 1A Auto. We've been selling auto parts for over 30 years. We're dedicated to delivering quality auto parts, expert customer service, fast and free shipping, all backed by our 100% satisfaction guarantee. Visit us at 1AAuto.com, your trusted source for quality auto parts.
I'm going to remove this cover. Two 10-millimeter bolts on this side and one over on the passenger's side. Remove those with a 10-millimeter socket and ratchet. Loosen the throttle body clamp with a flat blade screwdriver, and you just kind of pull up and down on it that whole ducting. There are tubes that go in the side. Once you pull it off the throttle body, you can twist a little bit and pull those tubes free.
Clamp for the air filter, pull that off. There's two connectors, one easy to see here. Press down on the tab and disconnect. You may press on the tab. Use your screwdriver, pry a little bit, help loosen it up. Connectors off. Then, there's another connector. Pres the tab and disconnect, and the intake tube comes up and out. You want to move this little intake box out. Just twist and pull, and then throttle position sensors right in behind. Remove the lead by pressing on a tab. It's held in by two Phillips screws. These screws, you may want to, maybe a good idea tap in the screwdriver in, tap with a hammer. Then, turn counterclockwise and tap with the hammer at the same time to get them loose.
Here’s the old sensor from the vehicle. Here’s the new sensor from 1A Auto. You can see they're exactly the same dimensionally. It's going to bolt in and go in. If you're getting bad readings to your engine from your throttle position sensor, then this will fix your problem.
For reinstalling, put some thread sealant on the screws. Tap on in. Put the sensor in place. Make sure it goes on to the arm inside, and then put your two Philips screws back in again with some thread sealant and tighten them up. Got on nice and firm, and then reconnect your lead.
Put your air intake in place. In place over here, tab winds up there and this clamp goes on. Just reach down, make sure nothing's getting pinched. Lock that down into place and that's your flow connection, reconnect it, reconnect this connector. Then, put this back in here, tube down there goes in, in there. Flat blade screwdriver to tighten up the clamp that holds it onto the throttle body. Put the tall body cover back in place. These fit kind of… Move it around a little bit. Figure out where the bolt hole is on that. I'm actually cheating. Just looking right through here. I can see there. Start it up, and then push this side down into place. Start my two bolts over there, and then tighten them up.
Thanks for watching. Visit us at 1AAuto.com for quality auto parts, fast and free shipping, and the best customer service in the industry.

Got the part quickly. Installed it in a few minutes. Can't say the same about the old part. Took longer to get the screws loose. They were in pretty tight. Luckily I had removed the throttle body elbow to clean it so I put the elbow in my vise so I could get some muscle on the screws. The new part works great. Would recommend getting the aprt.
Excellent service

Yes, it is possible that a bad throttle position sensor will prevent the vehicle from starting. however, that is not always the case. There could be multiple reasons why you're having this particular problem. We suggest taking your vehicle to a nearby reputable shop to identify the cause. Once you know the cause, we'll be happy to see if we carry the parts and how-to videos needed for your repair.

Will this cause a loss of power?December 31, 2020
Brett S

No this sensor tells the computer how open or closed the throttle body is .
And this sensor isnt good as mine went out instantly.
Always replace motorcraft sensors with motorcraft or Napa sensors

I agree with Chris however, it can cause a seat of the pants feeling of loss of power. If you step all the way to the floor and the signal the TPS is sending is 50% throttle then it will feel as though the car is losing power because it will only deliver the injector shot for a 50% throttle position.
