If your Chevy is acting up and you think the throttle position sensor may be to blame, you’ll need to know how to reset it. The throttle position sensor, or TPS, is a small electronic device that measures the throttle’s angle and sends a signal to the engine control unit, or ECU. The ECU then uses this information to adjust the air/fuel mixture and ignition timing.
Resetting the TPS is a simple process that can be done in a matter of minutes.
If you’re having trouble with your Chevy and think that the throttle position sensor may be to blame, you’ll need to know how to reset it. This process is actually quite simple and only takes a few minutes to do.
First, locate the throttle position sensor on your Chevy.
It’s usually located on the throttle body, near the air intake. Once you’ve found it, disconnect the negative battery cable. This will help to prevent any electrical damage while you’re working.
Next, use a flathead screwdriver to loosen the two screws that hold the throttle position sensor in place. Be careful not to damage the sensor as you remove it.
Once the sensor is removed, take a look at the electrical connector.
You’ll notice that there are three wires attached to it. The colors of these wires will be black, white, and brown.
Using a small piece of wire, jump the black and white wires together.
This will bypass the sensor and allow the engine to start. If it starts, then the throttle position sensor needs to be replaced.
If you’re still having trouble, you can also try resetting the computer on your Chevy.
This can be done by disconnecting the negative battery cable for 30 seconds. After reconnecting it, turn on the ignition and see if the engine starts.
If you’re still having trouble, it’s best to take your Chevy to a mechanic to have it checked out.
They’ll be able to diagnose the problem and get you back on the road in no time.
What happens if you disconnect throttle position sensor
If you disconnect the throttle position sensor, the engine will not be able to regulate the air and fuel mixture correctly. This will cause the engine to run lean, which can lead to engine damage.
What to do after replacing throttle position sensor
If you’ve recently replaced your throttle position sensor, there are a few things you should do to ensure proper functioning. First, check your engine’s idle. If it’s higher than usual, you may need to adjust your idle speed screw.
Next, check for any engine codes that may have been triggered by the replacement. If everything looks good, take your vehicle for a test drive to make sure the sensor is working properly.
How to reset throttle position sensor
If your car is acting up and you suspect that the throttle position sensor (TPS) may be the culprit, you’ll be happy to know that it’s easy to reset this sensor. In this blog post, we’ll show you how to reset the TPS in just a few simple steps.
First, locate the TPS on your car.
It’s usually located on the throttle body, near the air intake manifold. Once you’ve found it, disconnect the electrical connector from the sensor.
Next, use a small screwdriver to loosen the retaining screws on the sensor.
Be careful not to lose these screws, as they are often very small.
With the retaining screws loosened, you should be able to pull the sensor out of its housing.
Once the sensor is removed, you can clean it with a cloth or compressed air.
If the sensor is very dirty, you may need to use a wire brush to remove all the built-up grime.
Once the sensor is clean, you can re-install it in the housing and reconnect the electrical connector. Be sure to tighten the retaining screws so that the sensor is secure.
Now, start up your car and see if the problem has been fixed. If not, you may need to repeat the steps above or consult a mechanic for further diagnosis.
Gm throttle position sensor relearn procedure
If you own a GM vehicle, you may have heard of the throttle position sensor relearn procedure. This procedure is necessary when the throttle position sensor (TPS) needs to be replaced. The relearn procedure ensures that the new TPS is properly calibrated to the vehicle.
If you’re not familiar with the throttle position sensor, it’s a device that measures the angle of the throttle plate. This information is then used by the engine control unit (ECU) to determine how much fuel to inject and when to ignite the spark plugs.
If the TPS is not properly calibrated, the engine will run poorly and may even stall.
That’s why it’s important to follow the relearn procedure when replacing the TPS.
The relearn procedure is relatively simple. First, make sure the battery is fully charged.
Then, with the engine off, disconnect the negative battery cable. Next, connect a scan tool to the vehicle’s diagnostic port.
Once the scan tool is properly connected, start the engine and let it idle for about two minutes.
Then, turn the engine off and reconnect the negative battery cable.
Finally, start the engine again and let it idle for another two minutes. The relearn procedure is now complete and the new TPS should be properly calibrated.

How do you reprogram a throttle position sensor?
When it comes to your car’s throttle position sensor, orTPS, there are a few things you should know about how to reprogram it. This part of your car is important because it helps to regulate the air and fuel mixture that goes into your engine. The TPS is also responsible for telling your car’s computer how far the throttle is open, which in turn affects how much power your engine produces.
If you’re having trouble with your car’s throttle response, or you’ve noticed that the engine is running rough, it might be time to reprogram the TPS. Here’s what you need to know about how to do just that:
What You’ll Need:
-A new TPS
-A Phillips head screwdriver
-A flathead screwdriver
-A drill
-A 3/32” drill bit
-A wire tap
-A voltmeter
-A friend (optional)
Step One: Remove the Old TPS
Start by disconnecting the negative battery cable from your car. This will help to prevent any electrical shorts while you’re working. Next, locate the TPS on the side of the throttle body and use the Phillips head screwdriver to remove the two screws that hold it in place.
With the screws removed, you should be able to pull the old TPS off of the throttle body. If it’s stuck, you can use the flathead screwdriver to gently pry it loose.
Step Two: Install the New TPS
Now it’s time to install the new TPS. Start by lining up the new sensor with the holes in the throttle body. Once it’s in place, use the Phillips head screwdriver to screw it in.
How do you calibrate a throttle position sensor on a Chevy?
A throttle position sensor (TPS) is a sensor used to monitor the position of the throttle in an internal combustion engine. The TPS is used to help control fuel injection and ignition timing. In a fuel-injected engine, the TPS is also used to help determine the amount of air needed for the engine to run properly.
The TPS is usually located on the side of the throttle body.
To calibrate a TPS, you will need to adjust the sensor so that it is reading the correct throttle position. This can be done by turning the sensor until the reading on the voltmeter is within the specified range.
Once the sensor is calibrated, you can then test the engine to make sure that it is running properly.
Do you have to reset computer after replacing throttle position sensor?
No, you don’t have to reset your computer after replacing your throttle position sensor. However, it may be necessary to clear your vehicle’s computer memory of any codes that have been stored related to the faulty sensor. Consult your vehicle’s service manual for specific instructions on how to clear the codes.
How do I reset my electronic throttle control manually?
If your electronic throttle control system is giving you trouble, you may be able to reset it manually. Here’s how:
First, disconnect the negative battery cable.
This will help prevent any electrical shorts while you’re working.
Next, locate the throttle control motor on the throttle body. There will be two electrical connectors on the motor – one for power and one for ground.
Using a voltmeter, check for continuity between the two terminals on the power connector. There should be continuity. If there is no continuity, the throttle control motor is faulty and will need to be replaced.
Now, check for continuity between the two terminals on the ground connector. There should be no continuity. If there is continuity, the throttle control motor is faulty and will need to be replaced.
If both the power and ground checks are good, reconnect the negative battery cable and start the engine. The throttle control system should now be reset and working properly.
