What causes an electronic throttle control light to come on?
The most common causes of an electronic throttle control light are a faulty throttle control sensor or a faulty throttle accelerator pedal position sensor. But while those are the most common causes of an electronic throttle light, they aren’t the only things that could be going on.
Where is the electronic throttle control located on a car?
The electronic throttle body (ETC stands for electronic throttle control) is located down low in the front of the car… just follow the fresh air duct.
What happens if you lose control of the throttle?
While this system allows for better air to fuel ratios for better fuel economy and engine performance, the tradeoff is that if a sensor or actuator breaks, you lose control of your throttle. That’s why vehicle manufacturers packed their vehicles full of sensors and an entire system to monitor your electronic throttle control.
What does it mean when ECM tells you to open throttle?
Just because your vehicle’s ECM tells the throttle to open a specific amount doesn’t mean that the ECM trusts that it will. It actually relies on the throttle control sensor to tell it how far the throttle has actually opened and makes fuel-to-air ratio adjustments based on that.

What does electronic throttle control ( etc ) mean?
This computer is known as an ECU or a PCM and it comes with every vehicle you buy. Along with an ECU, there are many other small electronic components like an Electronic Throttle Control (ETC). ETC has a very important function to perform.
Why does my throttle control go into limp mode?
Solution: This indicates a serious failure of your throttle control system. The engine computer is programmed to go into limp mode when the system malfunctions, in an attempt to limit your speed and prevent damage to the engine. It can be caused by a sensor failure, or even by outside electromagnetic interference.
What happens if the electronic throttle fails in a car?
The electronic throttle body is controlled by the computer engine of the vehicle in modern cars. So, if the throttle body fails then, the computer engine controls it and interrupts from moving the valve and, consequently, helps to save the whole engine from any extensive damage. And then, the engine seems to have very poor idling.
What does trouble code mean on throttle control?
The associated trouble code should identify a problem with the throttle controller, which can then be repaired. If the throttle control system gets damaged, erratic operation may cause a stumbling or hesitation when you try to accelerate.

Why does my Dodge Nitro have no throttle control?
If the dealership is saying no codes exist, it’s possible; although highly unlikely that the source of the problem is the ECU itself or there is a relay issue with the electronic throttle control on your Dodge Nitro.
What does it mean when your throttle control light comes on?
When the electronic throttle light comes on while driving, it may be a warning sign that your vehicle needs repair, especially from the throttle control system. You might not see white smoke coming out from the engine of your vehicle.
How does the electronic throttle control work in a car?
The electronic throttle control is the modern version of what was operated by a cable in old cars. The gas pedal controls the job of your throttle control. In old vehicles, the gas pedal is connected by a cable that links it to the engine and is joined to a linkage fixed to the carburetor or throttle body.
Why does my car have a low throttle response?
Here are three of the most common reasons for poor throttle response and what you can do to improve your vehicle’s performance. The first place that an automotive technician will likely inspect when the throttle response is low is the fuel filter. The filter is responsible for removing debris to avoid engine issues and to improve fuel economy.
When does the ASR light come on on a 91 500SL?
The ASR light on my 58,000 mile ’91 500SL recently began to come on after about a mile of driving and remains on until I shut the engine down, after which it repeats next time car is driven. I notice … read more
Can a malfunction indicator light come on at the same time?
While driving, the malfunction indicator light and the electronic throttle control light will both come on at the same time, (the mil will be steady and the etc light will be flashing) and the feeling of a sudden reduction of power.
What causes the throttle control light to go on?
The engine computer is programmed to go into limp mode when the system malfunctions, in an attempt to limit your speed and prevent damage to the engine. It can be caused by a sensor failure, or even by outside electromagnetic interference. Your mechanic can diagnose and fix the problem. Can I drive with the throttle control light on?
How to fix the electronic throttle on a car?
Then, wait for a minimum of 3 seconds. Now, press the accelerator pedal and do press and release five times amidst 5 seconds. Press the pedal again, and this time hold on pressing for around 20 seconds. At least until the engine light stops the blinking and then stays on.
Why does the throttle not work at all?
Because the connection between the gas pedal and the throttle is electrical, any disruption of the signals coming from the pedal will affect its acceleration. The throttle may operate properly at some times, but not at others.
How does the throttle position sensor work in a car?
A throttle position sensor is similar to the motor cortex in the human brain, it controls one of the most important components of the car that keeps your engine running like a throttle body. Picture a little module in the car that reads how far down you have pressed the gas pedal.
Can a bad throttle position sensor cause a car to shake?
A bad throttle position sensor can cause other issues on your car if left unattended. That’s right! If the sensor is faulty, it will cause your car to shake heavily. Eventually, if this issue is left unattended it will put major stress on your motor and transmission mounts to the point where they will give out and will need replacement.
How can you tell if your throttle position sensor is bad?
The most common symptom is your check engine light. This indicator is a vague symptom, as it could also point to a variety of issues, but you can expect to see it if there’s any issue with your throttle position sensor. Next, any unusual changes in your acceleration could be linked to this sensor.
What does the Check Engine light on a TPS sensor mean?
If your TPS sensor has turned on the check engine light, you may need to clear it with a scanner. The check engine light will not always go away after replacement of the TPS. The TPS monitors the position of the throttle valve, which regulates how much air is supplied to the engine.
How is the throttle position sensor ( TPS ) used?
The throttle position sensor (TPS) is used to inform the powertrain control module (PCM) of throttle position. The PCM uses this information to determine control of various output devices, such as the fuel injectors, transmission shift solenoids, etc.
