To address any of these situations, it is important to take note of when exactly the problem occurs: The idle Air Control motor may not be operating properly.The idle Air Control valve may not be fully closed, causing the throttle valve to remain open.
Other possible causes of the Throttle Fault Light: Have your vehicle serviced as soon as possible, especially if you notice that the engine is idling too fast or too slow. If your vehicle has a Throttle Position Sensor (TPS), and the throttle fault light is ON, there may be a problem with the throttle position sensor. If the throttle valve does not move or only moves slightly, the idle speed is not adjusted properly. The throttle valve should move, indicating that the idle speed is controlled by the throttle valve. Turn the ignition switch ON (do not release the accelerator pedal). With the engine off, push and hold the accelerator pedal to the floor. Here is how you check the throttle valve: Pull over as soon as it is safe to do so, apply the parking brake, and shut off the engine. If the throttle valve is damaged, do not drive your vehicle until you have your system checked by a qualified technician. If the throttle fault light comes ON, there may be a problem with the throttle valve, which restricts the flow of air to your engine.

Throttle fault lights alert drivers when there is a problem with the throttle. This is how your warning light will look like (it’s an inverted parenthesis with a lightning bolt): If the light is steady, there may be a problem with the sensor.
If it is blinking, this means that there is something wrong with the electronic throttle control system. When the throttle fault light comes on, it is very important to determine the cause of the problem.Ĭheck to see if the light is blinking or steady. If you notice that you have started to drive slower than usual, it is very likely that you are having a problem with the electronic throttle control system.
