What Causes the Electronic Throttle Control System to Fail?

As previously stated, in order for everything to run smoothly, there needs to be a perfect ratio of air and fuel flowing into the engine. If  any disruption of this ratio, a problem may occur within the throttle body.
There are a few reasons that a problem may occur within the Electronic Throttle Control System.
  • One indicator may be Dirt or Wear and Tear
On the interior of your vehicle’s engine, dirt may build that can obstruct the airflow or fuel flow to the engine.
If there is dirt or grime, an uneven or rough surface may appear in the throttle body, which in turn can disrupt the flow.
  • Another answer may be Electrical Problems
Electronic problems can cause for inaccurate or a misread of information transmiting to the vehicle’s computer.If this occurs, the throttle body may have an issue receiving clear information from the sensors in the accelerator pedal.
  • A Vacuum Leak is another potential problem within the ETC.
If there is a leak, there will also be a disruption of airflow. Which  may cause problems for the throttle system. An indicator of a vacuum leak may be a high engine idle, which is caused by too much air. In this event, the systems inside your vehicle should illuminate the Check engine light.
