Engine Throttle Control Problems

The idle control valve sits on the throttle body and is responsible for adjusting the amount of air that enters the engine.

Engine throttle control problems.

The throttle controller is controlled electrically as opposed to the older mechanical cables that ran from the throttle pedal to the throttle body. An engine needs air and fuel to make power. For most of the 20th century throttle control involved a direct mechanical connection between your accelerator and the engine. Alternatively the throttle valve will open slightly if you are only driving to keep the air fuel mixture at the optimum level.

You notice a lack of power or poor engine performance. The electronic throttle control system within most vehicles is constructed with three important parts. The tps provides the most direct signal to the fuel injection system of what power demands are being made by the engine. If the throttle body isn t supplying.

The accelerator pedal the throttle valve and a control module or pcm. If it fails you will face countless problems in your daily driving. In some instances the electric signal is disrupted whether due to a loose electrical wire a relay control issue or damage done to a sensor. Below are common symptoms of a faulty tps.

Your check engine light is on. The throttle control unit is necessary to ensure that you get the optimum amount of power from your engine. In an etc system the control module constantly monitors throttle body performance. A faulty throttle position sensor sends incorrect information to the ecm resulting in various issues in the engine its performance and fuel economy.

In most of the cases all of these symptoms will show together making it easier to detect the faulty component. In the traditional carbureted engines the throttle body is integrated into the carburettor while in the modern fuel injected engines the throttle body is installed between the air filter and the intake manifold. However the gas pedal is used to control the angle of the butterfly valve which regulates the amount of air entering the engine. The throttle position sensor tps is part of your vehicle s fuel management system and helps ensure that the correct mixture of air and fuel is delivered to your engine.

If it detects a problem with the throttle body it will turn on the check engine light.
