The Ride-by-Wire technology does away with this mechanical linkage. Instead, it has sensors and actuators that sense the throttle inputs and controls the fuel-air supply that goes into the engine. As soon as the accelerator is twisted, the actuators in the throttle body sense the input and change the throttle opening according to that.
The pull cable is what does most of the work here. This is the cable that pulls open the valve when you turn the throttle. It allows air to get into your engine. The push cable is a little more confusing, since cables can’t actually push. Though there are a few other names for these cables, push and pull is the most common.
Once access to the throttle tube is available, the ferrules can be slipped from it and the cables can hang loose. If they are attached to a carburetor, there is usually a spring loaded end that needs to be gently released. A similar arrangement is on fuel injected types. Throttle by wire doesn’t require any cables to be changed.
Step 1: Basic Circuit. The 3-wire throttles use a hall effect sensor in the grip. The motor controller sends it circa 5v and depending on how hard you have your throttle on, it sends back a voltage in the range of 0.85v to 4.0v. 0.85v - Zero throttle. 4.0v - Full throttle.
We have an indirect connection to the throttle through the ECM by way of multiple sensors. The APP(accelerator pedal position sensor) and the TPS (throttle position sensor) are the inputs and outputs of this system. The APP “requests” the computer to send signal to the TPS to open the throttle(or close it).
