Brake pedal position sensor is an important safety feature in your car. It helps the computer to know when the brake pedal is applied so that it can provide the appropriate level of braking power. If this sensor is not working properly, it can cause the brakes to feel spongy or unresponsive.
In some cases, it may even cause the brakes to fail completely. Fortunately, you can reset the brake pedal position sensor yourself with a few simple steps.
- First, locate the brake pedal position sensor
- This is usually located near the brake pedal itself
- Next, disconnect the power to the sensor by unplugging it from its power source
- Once disconnected, use a small screwdriver or other tool to gently pry the sensor out of its housing
- With the sensor removed, take a look at its contact points and clean them off with a rag or cotton swab if necessary
- To reinstall the sensor, simply reverse the steps you took to remove it
- Make sure that it is properly seated in its housing and reconnected to its power source before moving on
How to Calibrate Brake Pedal Position Sensor
Brake pedal position sensors are an important part of any vehicle’s braking system. They help to ensure that the brakes are applied evenly and with the correct amount of pressure. If your brake pedal position sensor is not working properly, it can lead to uneven or incorrect braking, which can be dangerous.
Calibrating your brake pedal position sensor is a relatively simple process that you can do at home with a few tools. First, you’ll need to find the right location for the sensor. The best place to mount it is on the firewall near the brake master cylinder.
Once you’ve found the right location, use a drill to make two holes for the mounting screws. Next, you’ll need to connect the power wire to the positive terminal of your battery and ground the negative wire to a metal surface on your car. Then, use a multimeter to test the voltage output of the sensor.
It should be between 0.5 and 4 volts when measured from either terminal while pressing down on the brake pedal slowly. If everything looks good so far, it’s time to install the sensor in its final location and reconnect all of the wires. Make sure that all connections are tight and secure before testing out your new brake pedal position sensor!
How Do You Relearn a Brake Pedal Position Sensor?
If you need to relearn your brake pedal position sensor, there are a few things you’ll need to do. First, find the sensors on your vehicle. They’re usually located near the brake pedal itself or in the master cylinder.
Once you’ve found them, you’ll need to clear any codes that may be associated with them. To do this, disconnect the battery and allow the car to sit for at least 30 minutes. Once the codes have been cleared, you’ll need to reconnect the battery and start the car.
With your foot off of the brake pedal, press and hold the “learn” button on your sensor until the light on it starts blinking. This indicates that it’s in learn mode. Next, slowly press and release the brake pedal 20 times while remaining in learn mode.
After you’ve done this, turn off your car and wait a few seconds before restarting it. The final step is to test your brakes by driving around safely at low speeds until you’re confident they’re working properly again.
What Happens When Brake Pedal Position Sensor Fails?
When a brake pedal position sensor fails, it can cause the brakes to stop working properly. This can lead to serious accidents if the vehicle is not able to stop in time. The brake pedal position sensor is responsible for sending a signal to the electronic control unit (ECU) when the brake pedal is depressed.
If this signal is not received, the ECU will not activate the brakes. In some cases, the brake light on the dash may also come on as a warning to the driver that there is a problem with the braking system.
What is the Sensor on the Brake Pedal Called?
When you press the brake pedal in your car, you’re activates the brakes. But how do the brakes know when to stop? That’s where sensors come in.
The sensor on the brake pedal is called a Brake Position Sensor (BPS). The BPS tells the car’s computer how far down the pedal is being pressed. This information is used to calculate how much braking force to apply.
Brake position sensors are important safety features. If they weren’t there, it would be very easy to accidentally over-brake and cause an accident. So, next time you hit the brakes, remember to thank your BPS for helping keep you safe!
How Do You Adjust a Brake Pedal Switch?
If your car has an automatic brake pedal switch, there is a good chance that it will need to be adjusted at some point. Here is how you can adjust a brake pedal switch:
1. Park your car on a level surface and set the parking brakes.
2. Locate the adjusting nut on the back of the pedal switch. 3. Turn the adjusting nut clockwise or counterclockwise until the brake light comes on when you depress the brake pedal halfway. 4. Test the brake lights to make sure they are working properly.

The brake pedal position sensor is used to measure the distance that the brake pedal has been depressed. This information is then used by the electronic control unit (ECU) to determine how much braking force to apply. If the sensor is not working properly, it can cause the brakes to apply too much or too little force, which can lead to an accident.
If you suspect that your brake pedal position sensor is not working properly, you should take it to a mechanic for diagnosis and repairs. In some cases, the sensor may just need to be reset. Here are instructions on how to do this:
1. Park your car in a safe place and set the parking brake. 2. Disconnect the negative battery cable. 3. Remove the bolts that secure the brake pedal position sensor to the firewall or bracket.
4. Pull out the old sensor and disconnect any wiring harnesses attached to it.
