What is a Throttle Body Sensor and How Does it Work?
A throttle body sensor, also known as a throttle position sensor (TPS), is an electronic device that measures the position of the throttle plate in an internal combustion engine. It is typically located on the side of the throttle body and is connected to a cable or electronic signal from the accelerator pedal.
The TPS sends this information to the engine control unit (ECU) which then adjusts fuel delivery accordingly. The TPS works by measuring changes in voltage as it moves with the opening and closing of the throttle plate.
As air enters through an intake manifold, it passes through a butterfly valve called a throttle plate which regulates how much air enters into each cylinder for combustion. When you press down on your accelerator pedal, this opens up more of the butterfly valve allowing more air into each cylinder for increased power output.
The TPS measures these changes in voltage and sends them to your ECU so that it can adjust fuel delivery accordingly for optimal performance. You can learn more about this in our guide on what does a throttle body do.
In addition to providing feedback about how much air is entering each cylinder, a properly functioning TPS can also help improve fuel economy by ensuring that only enough fuel is being delivered when needed instead of wasting excess fuel when not necessary.
A faulty or malfunctioning TPS can cause poor performance due to incorrect readings being sent to your ECU resulting in improper fueling adjustments which can lead to decreased power output and reduced efficiency overall.
Common Symptoms of a Faulty Throttle Body Sensor
A faulty throttle body sensor can cause a variety of symptoms in a vehicle. These symptoms may include reduced engine power, poor acceleration, stalling, and rough idling. The Check Engine Light may also be illuminated on the dashboard. In some cases, the vehicle may not start at all due to an issue with the throttle body sensor.
The throttle body is responsible for controlling the amount of air that enters the engine’s combustion chamber. When it malfunctions, it can cause an imbalance in air-fuel ratio which can lead to poor performance and other issues with the vehicle’s operation.
If you suspect that your vehicle has a faulty throttle body sensor, it is important to have it inspected by a qualified mechanic as soon as possible. They will be able to diagnose any issues and recommend appropriate repairs or replacements if necessary.
