Honda cars have a throttle position sensor that tells the computer how far the accelerator pedal is depressed. If this sensor gets out of adjustment, it can cause problems with idling and power delivery.
You may need to reset the throttle position sensor in your Honda if you’ve replaced the battery, cleaned the engine, or done any work on the throttle body assembly.
To reset the throttle position sensor in a Honda, disconnect the battery for 15-30 minutes and allow the ECU to reset. When you start the engine again, the TPS should reset and function properly. If that doesn’t work, use the function of the OBD2 scanner to initiate a TPS reset.
The Throttle Position Sensor (TPS) is located on the throttle body. The TPS is responsible for sending signals to the engine control module (ECM) that tell the engine how much fuel to inject into the cylinders. If the TPS is not functioning properly, it can cause the engine to run lean or rich.

The throttle position sensor is essential to the proper functioning of a Honda. The sensor helps to maintain the acceleration and controls the combustion as well as the whole functionality of the engine.
The throttle position sensor is located on the side of the throttle body in most cases. The throttle body is the round, metal piece that is attached to the intake manifold.
The throttle position sensor also varies depending on the model and trim of your Honda. Older vehicles have a mechanical throttle position sensor, which is usually found on the side of the throttle body.
Newer vehicles have an electronic throttle position sensor, which is located on the top of the throttle body. However, these sensors still have the same function.

TPS works by measuring the amount of air that is entering the engine. The TPS then sends a signal to the computer, which uses this information to calculate the correct amount of fuel to inject into the engine. This helps maintain optimal performance and fuel economy.
When the driver applies pressure on the gas pedal, it opens the throttle valve. The angle of this opening is determined by how far the gas pedal is pushed down. This angle is then translated into an electrical signal that tells the computer how much fuel to inject.
Signs That You Should Reset the Throttle Position
Resetting the throttle position sensor is a simple process that can be done at home with a few tools. There are several reasons why you might need to reset the throttle position sensor. Here are some;
1. Check If the Engine Light Comes On
If the check engine light in your Honda comes on, it could be for several reasons. One of those reasons could be that the throttle position sensor needs to be reset. This is because the check engine light is connected to the computer, which monitors all of the sensors in your vehicle.
2. Honda Won’t Start
Another reason you might need to reset the throttle position sensor is if your Honda won’t start. This is usually caused by a problem with the sensor itself or with the wiring.
If you have checked all of the other possible causes of why your Honda won’t start, then resetting the throttle position sensor should be your next step.
3. Poor Response from the Gas Pedal
The gas pedal is connected to the throttle body, which is controlled by the throttle position sensor.
If you are having problems with the response from the gas pedal, it could be because the sensor needs to be reset. This is because the sensor controls how much air enters the engine and, as a result, how much power is produced.
What Causes Throttle Position Sensor Failure
Now that we already know how important the throttle position sensor is, let’s look at some of the reasons the TPS can go bad. One of the most common reasons is because of a loose connection. This can happen because of corrosion or simply because the connection was not tight enough in the first place.
Another reason is because of a build-up of carbon deposits on the sensor. This can happen over time and will eventually cause the sensor to fail.
Yet another reason the throttle position sensor can go bad is because of physical damage. This can happen if the sensor is hit by something or if it sustains some other type of physical damage.
FAQ
Can I Drive With a Bad Throttle Body?
Yes, you can drive with a bad throttle body, but it is not recommended. Driving with a bad throttle body can cause the engine to run lean, which can lead to engine damage.
How Much Does It Cost to Replace a Throttle Body?
The cost of replacing a throttle body varies depending on the make and model of your vehicle. In most cases, it will cost between $200 and $500 to replace the throttle body.
When Should I Clean My Throttle Body?
There is no specific time frame that you should clean your throttle body, but it is generally recommended you should clean your throttle body every 30,000 miles or so to prevent the build-up of carbon deposits.
However, if your throttle body is particularly dirty, then you might need to clean it more often.

Cleaning your throttle body is a relatively simple process that can be done at home with a few tools. You will need to remove the throttle body from the vehicle and then clean it with a carburetor using the following steps:
- First, remove the throttle body from the vehicle. This can be done by disconnecting the negative battery terminal and then removing the bolts that hold the throttle body in place.
- Next, clean the throttle body with a carburetor cleaner. You can do this by spraying the cleaner into all of the nooks and crannies of the throttle body.
- Finally, reinstall the throttle body and reconnect the negative battery terminal. Once you have cleaned the throttle body, you should reset the throttle position sensor. This can be done by disconnecting the negative battery terminal and then removing the bolts that hold the sensor in place. Remember to reconnect the negative battery terminal once you are done.
How Do I Test the Throttle Position Sensor?
There are a few ways you can test the throttle position sensor to see if it is working properly. One way is to use a multimeter to test the resistance of the sensor. Another way is to use a scan tool to check for codes.
When you suspect that your throttle position sensor is not working properly, it is important to have it diagnosed and repaired as soon as possible. Driving with a bad throttle position sensor can cause engine damage.
How Does the Throttle Plate Work on a Honda?
The throttle plate on a Honda is responsible for controlling the amount of air that enters the engine. The position of the throttle plate is controlled by the throttle position sensor. When the accelerator pedal is depressed, the throttle position sensor sends a signal to the computer telling it to open the throttle plate.
This allows more air to enter the engine and increases power. When the accelerator pedal is released, the throttle position sensor sends a signal to the computer telling it to close the throttle plate. This decreases power and helps the engine run more efficiently.

Resetting the TPS is a simple process that can be done at home with a few tools. First, connect your scanner to the OBDII port. After you’ve plugged in the scanner, start the engine but don’t turn it on. From the menu on your scanner, go to “TP Position” and choose “Reset.”
Turn the ignition off and back on after selecting the reset option. The TPS has been reset, and it should now be operating properly.
The TPS works by sending signals to the ECU that tell it how far the throttle is open. If the TPS is not working properly, it can cause engine damage.
It is important to have your TPS diagnosed and repaired as soon as possible if you suspect it is not working properly. Driving with a bad TPS can cause engine damage.
