00:00According to the NHTSA, people waste tens of billions of dollars yearly on unnecessary car

00:06repairs. One reason for this waste is not knowing how to reset the throttle position sensor.

00:12In this video, I'll show you five easy ways to reset the TPS. I'll also share a very important

00:19maintenance tip at the end. Method 1. Perform a basic ignition reset of the throttle position

00:25sensor. One of the best ways to reset the throttle position sensor is also the cheapest. If you've

00:31been experiencing the symptoms of a faulty TPS but the check engine light isn't showing, this is the

00:37method to use. You don't need any special diagnostic tools, and this method works for most modern cars.

00:45A basic ignition reset is also called a manual reset, or TPS relearn procedure. It takes just

00:52seven minutes and anyone can do it. First, park your car on a level surface, pull the handbrake,

00:59and switch off the engine. Next, you're going to turn the key to the on position, but don't start

01:04the car. The dashboard will light up and show a bunch of things, including the check engine light,

01:10but ignore them. The third step is to depress the accelerator slowly. It should take three to four

01:16seconds to push it down to the floor. Hold it down for about three seconds, then slowly lift your foot

01:22off. This should take another four seconds. You're going to repeat this process two or three times.

01:28After the fourth press, leave the ignition in the on position for another 30 seconds.

01:34Remember that it should have been in that position the entire time. This process will cause the ECU

01:39to relearn the TPS settings. Switch off the ignition and wait for a few seconds. Finally, start the engine

01:47and let it idle for about five minutes. If the car is idling smoother than before, it's time to take

01:53it for a test drive. Pay attention to the throttle response, engine sounds, and any problems that were

01:59there before. If everything is back to normal, it means the reset worked. This method works like a charm,

02:07and most drivers never use any other method. However, if the check engine light is showing,

02:13the best method to use is the next one. Before we dive into the next method, if you're new here,

02:19subscribe. I'll give you a second. All set? Great. Let's keep rolling.

02:25Method two. Reset the throttle position sensor using a diagnostic tool. If your car has an advanced

02:32system and it is showing a TPS error code, this method will sort it out. You're going to need an

02:38advanced OBD2 scanner for this one. Not every scanner can reset the TPS, so make sure yours can.

02:47Otherwise, click the link in the description for the one we recommend.

02:51Foxwell scanner A-NT809. As with the first method, you need to park the car on a level surface with the

03:00handbrake engaged. Next, locate the OBD2 port in your car, which is usually under the dashboard.

03:07Plug in the scanner and turn the ignition to the on position, but don't start the engine.

03:14This will enable the OBD2 scanner to access the car's ECU. Next, look for TPS reset or throttle

03:21position sensor in the OBD2 menu. It might also be labeled as accelerator pedal position reset or idle

03:29relearn. Follow the instructions on the screen. The scanner might instruct you to carry out the

03:35first method or some variation of it. Ensure that you follow the instructions exactly.

03:41Once you're done, switch off the car and remove the scanner. The reset should be complete and it's

03:47time for a test drive. At this point, the check engine light should be gone. If it is and the car

03:53is moving smoothly, that's all you have to do. If the check engine light is still showing,

03:59the TPS might be damaged and need to be replaced. However, don't replace the TPS until you've tried

04:06the final method we're going to share. Method 3. Reset the throttle position sensor using the

04:12battery disconnection method. If you don't have an advanced OBD2 scanner and the first method didn't

04:18work, this is what you should try next. As usual, park your car securely on a flat surface. Switch off

04:25the engine and take the key out of the ignition. Next, use a wrench to disconnect the negative

04:30terminal of the battery. That's the side with a black cable cover. You can also identify it by the

04:37negative sign on top of it. When you unplug it, ensure the metal part of the terminal doesn't touch

04:43anything else. It will usually fit snugly right next to the body of the battery. You're going to leave

04:49the battery disconnected for 5 to 10 minutes. This process will clear out the ECU memory. Next,

04:56reconnect the negative terminal and switch the ignition to the on position, but don't start it.

05:02The dashboard will light up and this process will give the ECU time to recalibrate. After 30 seconds,

05:09start the car and let it idle for 5 minutes. If the car isn't idling smoothly, repeat the first method.

05:15But if it is, take it for a test drive and everything should be great. If the battery

05:21disconnect doesn't reset the TPS, it's time to pull out the big guns. Method 4. Throttle position.

05:29Sensor reprogramming. If you have replaced the throttle body recently, the previous methods won't

05:35work. They also might not work if the TPS is in very bad shape. That means your car has had sluggish

05:42acceleration, rough idling, and terrible fuel economy for months. In this case, you might need a more

05:49technical approach. However, even severe TPS problems can be fixed by the first method, so you should try

05:56that first. TPS reprogramming is a delicate method that requires a bit of time and patience. If you don't

06:04stick to the time frames, you might have to start the process all over again. Also, do not touch the pedal

06:10at any point until it's time for the test drive at the end. Before you begin, ensure that your car

06:16battery is in good condition. You can test it with a multimeter or a voltmeter. If the battery is still

06:22new, you don't need to test it. With that out of the way, park your car securely and switch off the

06:28engine. Give the engine a bit of time to cool off before you proceed. Five minutes should suffice.

06:34Next, disconnect the negative terminal of the battery, as explained earlier. After two minutes,

06:40reconnect the terminal. Leave the hood open and turn the ignition to the on position.

06:46Don't put the engine on just yet. Next, stand at the front of the car and listen for a soft buzzing

06:53sound from the throttle body. The buzzing means that the throttle is being reprogrammed and is

07:05learning its position. This sound should stop after about three to five minutes. Once it does,

07:11close the hood and go back into the car. Switch off the engine and remove the key from the ignition.

07:17After a minute or two, you can start the engine. Let the engine idle for about 10 to 15 minutes.

07:24This will give the throttle time to fully reprogram. Now you're ready to take the car for a gentle spin.

07:31Give the car a bit of time to warm up before you push it. If this method doesn't work,

07:36it means the TPS is in a worse state than expected. But don't worry. We still have one more trick up our

07:43sleeves. Method 5. Remove and clean the throttle position sensor. There are three reasons why none

07:51of the previous methods worked. The first is that the TPS has failed and needs replacing.

07:57The second is that it is too dirty to respond properly. The third reason is that there was

08:03nothing wrong with the TPS in the first place, and the fault is somewhere else. Before you try to

08:09replace the TPS or diagnose something else, see if this method works. For this, you're going to need

08:15throttle body cleaner, a rag, and a screwdriver. The first step is, you guessed it, to park the car

08:22securely on a level surface. Then you're going to disconnect the negative terminal of the battery.

08:27Next, you need to locate the throttle position sensor. It's usually on the side of the throttle body,

08:33which itself is on the intake manifold. Once you've located it, disconnect the electrical connectors.

08:40Next, carefully unscrew the TPS and remove it gently. You don't want to drop the TPS and get it

08:47even dirtier. Next, spray the throttle body cleaner on the TPS and a rag. Only use a small amount of the

08:54spray because we don't want it to be too wet. Wipe the TPS clean with the rag. Depending on the car and

09:01design of the TPS, you might also need a cotton swab for hard-to-reach areas. With that done,

09:07you're ready to reinstall the TPS. Put the screws on tight and plug in the electrical connectors.

09:14Reinstall the negative terminal of the battery and close the hood. Start the engine and let it idle

09:19for a few minutes. If it is purring like a kitten, test it to ensure everything is fine.

09:25Now you've learned how to reset the throttle position sensor, it's time for the bonus tip

09:34I promised. If you want to keep your car running smoothly, you need to clean the throttle body and

09:40TPS every 60,000 to 100,000 miles. In some cars, you need to do it more often, so consult the manual.

09:48You want to keep the throttle body free from dirt, grime, and carbon buildup. Otherwise,

09:54airflow will be restricted and the car's performance will dip. If you liked this video,
