Throttle position’s information is transmitted to the computer system installed in your car that is also called an ECM. This information is relayed by throttle position sensor that must be working fine at all times for correct information to be fed to your car’s computer. This information is then evaluated by the ECM that has a direct impact on fuel efficiency as well as the performance of your vehicle. The entire throttle system has parts that are mechanical and undergo wear and tear when the car is moving. Therefore, they need to be checked from time to time for optimal performance so they can feed correct information regarding your throttle position to the ECM. The computer system makes use of the data fed to it by the sensor to keep a control over the air intake of your vehicle that is an essential part of the overall performance. To maintain the smooth functioning of your vehicle, the ratio of the air-fuel mixture must be maintained that is dependent on the information the ECM receives from throttle sensor.
Bad throttle position sensor symptoms are quite simple to detect if you pay attention to how your car behaves along the route. If you notice any stalling in your car engine, you must get the throttle sensor checked because it is a clear sign that it is not functioning properly. Whether your car is being driven or it is in an idle state, engine stalling is a sure shot sign that the sensor is malfunctioning. It isn’t necessary that the stalling issue is a problem in your throttle sensor but getting it checked is a must if you don’t want the issue to get bigger. Delayed acceleration is another symptom that might indicate your throttle position sensor isn’t working fine and you should get it checked.
