Throttle lock functions similarly to cruise control in cable throttle cars, except it skips the actuator and the ECU and directly deals with the throttle body. Throttle lock works by locking the throttle cable and maintaining a constant amount of tension on the cable. This keeps the motorcycle cruising at a steady speed. Drive by Wire uses a stepper motor on the throttle bodi (es). The ECM (or in some cases a different module) reads the how far the accelerator pedal is pressed via a potentiometer-like device (think of your fuel gauge, same principle), and in turn sends this information to the stepper motor on the throttle body and/or ECM. So this is the maximum drive by wire throttle opening that the ECU can use in order to do the closed loop idle speed control. 20:24. This also effects the numbers in our base idle speed control table. 20:29. So in other words we've got a 0% to 100% range for our base idle speed duty cycle. 20:35. The TPS sensor is a potentiometer, a variable resistance that decreases in proportion to the throttle plate position. So the more open the throttle is, the less resistance is applied in the potentiometer. The TPS sensor is usually a 3 wire configuration. One wire is used for a +5V reference signal (sent by the ECU – Engine Control Unit Fly-by-wire (FBW) systems are semi-automatic, computer-regulated aircraft flight control systems that replace mechanical flight controls with an electronic interface. When the pilot moves flight controls, those movements are converted into electronic signals, which are then interpreted by the aircraft's flight control computers (FCC) to adjust 6 posts · Joined 2006. #1 · Jan 30, 2007 (Edited) i wanted to drive my gen 5.5 camry off of a cliff today. i am so sick of that stupid drive by wire system. all i want to have my foot attached to the engine driectly by steel cable, or thats how my gen 4 camry was. but this new gen 5.5 camry does its own thing. i tell it a little gas it .
