A throttle body varies the amount of air entering an engine, by using a flat valve (butterfly) that rotates inside a tube-shaped housing. In an electronically fuel-injected car, a throttle position sensor and air-flow sensor communicate with the main electronic control unit (ECU), which supplies the corresponding amount of fuel needed at the
The LS1 Corvette throttle body was the first electronic throttle body used with Chevrolet V engines. The throttle position sensor is mounted on the bank 2 side of the engine and the throttle shaft motor is mounted on the bank 1 side of the engine. The blade on this throttle body measures approximately 75 mm in diameter.

Search. This technical guide covers the four different throttle styles for electric scooters: trigger, thumb, twist, and wheel throttle. We cover their pros and cons, why you might choose one over another, repair considerations, and also give and also give you a crash course on basic ergonomics related to throttles.

Drive-by-wire technology employs electronic systems to trigger brakes, control steering, and fuel the engine in place of cables or hydraulic pressure. Throttle, brakes, and steering are the three primary driving components that drive-by-wire systems commonly replace with electronic controls. Electronic throttle control, brake-by-wire, and steer

PART 1: 1. Place your multimeter in Volts DC mode and with the red multimeter test lead probe the middle wire of the sensor's connector. This is the wire that connects to TPS connector terminal letter B in the illustration above. 2. Ground the black multimeter test lead on the battery negative (-) terminal.
Here is a chart that will show the wire color, description, and where the wire needs to go in the PCM plugs. The wire color and location shown match 2003+ express vans that had mechanical drive by cable throttle bodies. You CAN use the oil pressure sensor plug from a 2003+ harness for the throttle position sensor. Pay attention that the 5v ref
Set your multimeter to the 10 DC voltage range, place the black negative probe on the ground terminal of the TPS, and place the red positive probe on the reference voltage terminal of the TPS. If the meter does not read 5 volts, the TPS is bad. This is only one test out of the series of tests you carry out on the throttle position sensor and we
While discussing throttle-by-wire systems: Technician A says that a spring on the throttle shaft provides the limp-home feature. Technician B says that most systems have redundant processors and the TP and accelerator pedal sensors send redundant input signals. Who is correct? A. Tech A B. Tech B C. Both A and B D. Neither A nor B
Correct. Fly by wire throttles are driven by servo motors in conjunction with a potentiometer. In english, when you push the throttle it takes readings to see were it is, and then the servo opens the throttle to the correct place. The more readings it takes the better it is, but that takes a more powerful 'brain'.
Step 3: Snip off Z-bend ends of the wire. Step 4: Combine the new Z-bend with the old throttle cable. Before combining, make sure to make new and old Z-bends are of the same size. So, if you have a long Z-bend, trim it from one of the ends to make it similar in size to the Z-bend of the old cable.
The physical connection of the brake pedal with the brake assembly is removed and the brake pedal connects to sensors which, in turn, is connected to the ECU of the car. Here, the ECU again processes the signal and computes how much throttle has to be opened to fulfill the demand by the driver. Accordingly, it sends the signals to the actuator
SwampDonkey said: The new throttle is a standard Cyclone 6 wire. Its the second one I pictured. The second one you pictured has 5 wires, and is labeled as follows red +5 volts power cable. black negative power cable. green signal. yellow power positive. blue power positive or electric switch.
How does the throttle plate work on a car? The throttle plate shaft is connected to a small motor and spring that responds to inputs from the computer. At idle, the computer commands the throttle plate to crack open slightly, much like the old carburetors.

To put it simply; in a DBW system the cable linking the throttle pedal and the throttle body is replaced by electric motors and sensors. The sensors detect the pedal movement and activate the electric motors which in turn open or close the butterfly valve in the throttle body. How the Elite ECU controls DBW

If the throttle is open when starting on a throttle by wire bikes, it fools the sensor to think "this is the closed throttle position" and will idle fast. Shut off the bike and start it , just make sure you do not twist the throttle. I found this out after years of riding a carbed evo and switching to a FI TBW twin cam. I have an 03 5.3 that was pulled from a silverado. I will be converting it to a cable actuated throttle body. Please correct me if I am wrong about any of this.
The LS3 throttle body is built to work with a different E38 PCM as opposed to the LS2’s E40 PCM. That means that the two aren’t interchangeable from a stock wiring and programming perspective. As an end note, 2009+ LS3 engines use the same gold plate throttle body as the LS7. Chevy 6.2L Drive-by-Wire vs Drive-by-Cable
Step 2: Wiring the Throttle. The image here shows how I wired-in the resistors at the 3-pin connector. Using a bit of insulation to make sure none of the wires cross. Works like a charm - either full-on or full-off. That can put a heavy strain on the motor, controller and battery, so please keep that in mind. XRJgO.
