the electronic throttle body, the Throttle Position Sensors (2), and the Throttle Actuation Control (TAC) motor. The throttle body has a sealed housing mounted to the side of it, which contains the two Throttle Position Sensors (TPS) and the Throttle Actuation Control (TAC) motor. The elec-tronic throttle body assembly is connected to the ECM by The electronic throttle body (ETB) has three main components: It can be thought of as an embedded system that feeds information to the engine control module (ECM), along with readings from the cruise control system, mass airflow sensor, engine speed sensor, vehicle speed sensor, and accelerator position sensor. Throttle by wire is a simple, potentiometer style (think volume switch) design that when the throttle tube is moved, the values are calculated, and an electrical impulse is sent to the throttlebody, and a small electric motor moves the throttle plate, rather than manual linkage via cables. Throttle. cut off on brake. cut off on low battery. With no controller, it will run until the battery is fried and damaged. I believe that on a razor the throttle is a pot, so if you read it with an ohm meter, you could just put this value resistor in line with the throttle. 15 posts · Joined 2008. #1 · Oct 23, 2011. I have a friend who just purchased a 2012 Street Glide and twice now while riding at highway speed the engine just loses power. The engine doesn't die it just drops to an idle and the throttle isn't responsive. Once she comes to a stop and shuts the bike off and restarts it returns to normal. vEGD.
