If electromagnetic interference were strong enough to affect electronic throttle controls, the throttle control system is designed to shut down, not surge ahead. That's not to say that electronic throttle control systems are problem-free; rather, they've been designed with a number of failsafes that, if working properly, should prevent unexpected engine surges and acceleration.

Apr 3, 2023 · An electronic throttle control system has many benefits over a traditional cable system. First, electronic systems are more fuel efficient because the computer can spray the precise amount of fuel into the combustion chamber based on the throttle’s position. Next, the output of the sensors can easily be integrated with other electronic ...

In 2008 Harley-Davidson introduced a new throttle system called Electronic Throttle Control (ETC), which eliminates the throttle cables connecting the throttle and the throttle body and replaces them with an electronic connection. ETC is standard on all 2008 and 2009 touring models, including CVO touring models.
Four years ago a group of engineers set out to clean up the appearance of the big bikes handlebars. One item that really caught their eye was the throttle and return cable. Modifying or replacing them would go a long way toward making the bars less cluttered. The engineers also wanted to increase reliability and preciseness in the new system. The p...
When the project began, Magneti Marelli already had over one million electronic throttles on the road, mostly in over-the-road trucks operating in Europe. Delphis contribution would come in the form of technology and electronics used to enhance the system.
The ETC system consists of two main components; the throttle-grip sensor, and the throttle-control actuator. The throttle-grip sensor is made by Delphi, and the throttle-control actuator is manufactured in South Carolina by Magneti Marelli. The throttle-grip sensor is a cylindrical component housed inside the right end of the handlebar. The unit is...
Motorcycle enthusiasts are no different from the rest of the population when it comes to change; some embrace it, while others resist it. ETC immediately raised concerns among the latter group. What if the throttle sticks open? What if it sticks closed? Can I change out the handlebar? How much more will this cost me in the long run? For the answers...
One of the first and most important items addressed by Lance was the redundancy built into the system. He explained that there are two separate sets of magnetic sensors housed in the throttle-grip sensor, two throttle-position sensors at the throttle body, and two separate circuits built into the electronic control module. As the throttle is opened...
ETC has various advantages over traditional systems. It requires no maintenance, there are no cables to adjust, lubricate, or replace, and the system has an indefinite life span. Throttle positioning is far more accurate than it is with a cable system. This is beneficial for EPA testing as one of the tests involves riding the motorcycle on a dyno t...
Jan 27, 2022 · Crank-position sensors (CKP) are one of the primary electronic devices used to monitor the position and speed of the crankshaft for purposes of feeding the information to the PCM to control the fuel injection and ignition timing and other engine parameters. A throttle-position sensor (TPS) is located on the butterfly spindle/shaft so it can ...
May 16, 2021 · The electronic control is built with a module called the "electronic throttle control" or ETC system. This uses an input from a throttle position sensor and the engine’s current rpm. How does the electronic throttle control system work? Its essentially a loop feedback systems managed by wire and electronics.
Feb 12, 2023 · The electronic throttle control (ETC) light indicates that there is an issue with the throttle system. The throttle system includes the throttle body, accelerator pedal, and wirings. The electronic throttle control system controls and monitors the position of the throttle. While older vehicles use a cable that’s linked directly to the ...

Feb 17, 2021 · The Electronic Throttle Control system is the inner workers of the engine that signals the throttle when the pedal is pushed. The Electronic Throttle Control system within most vehicles is constructed with three important parts: the accelerator pedal, the throttle valve, and a control module or PCM. There is no direct cable that connects the ...
