Throttle Position Sensor

The throttle Position Sensor is an electronic device used to monitor a vehicle’s airflow. The sensor itself is normally located on the carburetor butterfly spindle, so it can directly monitor the throttle’s open or closed position. More sophisticated types of this sensor are even used in cars that do not have a carburetor.

In these cases, the device will act as if the throttle is closed, and the computer will relay information to the driver via the monitor. Most fuel-efficient vehicles have some gauge that displays the open position of the throttle.

It is important to keep this information current, and for this reason, most automotive aftermarket vehicle tuning and modification stores have their lines of carburetor gauges. Many times, these instruments are located directly next to or around the intake manifold.

While this may seem convenient, it is not always practical. For instance, many carburetors are not designed to work with a universal airflow system. Therefore, a mechanic would need to purchase or mount a universal gauge in order to use it with their specific vehicle.

When selecting a throttle position sensor, it is important to ensure that the device is mounted to the carburetor so that its signals can be read easily by your vehicle’s computer. Furthermore, you should purchase the appropriate sensor so that it is useful in your particular application.

In general, the more sensitive and versatile your sensor, the more likely you will get the most out of it. If you have questions about your vehicle’s carburetor sensor. It is advisable to consult a professional mechanic or carburetor tech at your local HONDA motorcycle shop. They will be able to answer any further questions you may have regarding this highly technical piece of equipment.

Working Of Throttle Position Sensor

The Throttle Position Sensor (TPS) is a sensor used to monitor the air in the engine. It is usually located on the throttle spindle/shaft to control the throttle position directly. The TPS was physically attached to the throttle valve and monitored its position through this contact.

It detects the position of the throttle valve and transmits it to the engine control unit. This sensor monitors how much the accelerometer pedal is depressed and outputs a current that determines the pedal’s position. The position of the pedal adjusts the airflow of the engine.

If the valve is open, a large amount of air is drawn into the engine and vice versa. The output signal of this sensor, together with other sensors, is transmitted to the engine control unit, accordingly determining the amount of fuel injected into the engine.

The sensor reads these changes and communicates with the ECM to determine the correct throttle position. This sensor is a 3-wire potentiometer. First, a wire is applied to the resistive layer of the sensor with a voltage of 5 V. And the second wire is used for ground, and the third wire connects to the potentiometer wiper and provides input to the engine control system.

Your car’s computer determines how much fuel should be supplied to the engine at any given time by reading them. This is a simpler process and can vary from manufacturer to brand or model to model.
