The pcm sends a digital signal to a stepper motor, in the throttle body, which opens to increase the vehicle's speed. The throttle body is the device that regulates the amount of air that the engine is sucking in.

If your chevy aveo has p2135 it is considered drive by wire.
Throttle body service meaning. Intermittent loss of throttle control. Injector pressures range from 13 to 16 psi (low pressure system) or 35 to 60 psi (high pressure system. Because the connection between the gas pedal and the throttle is electrical, any disruption of the signals coming from the pedal will affect its acceleration.
You press the gas pedal. Simultaneously, throttle position sensors let the pcm know how much the throttle has moved. A lever or pedal controlling such a valve.
It happened twice and would disappear after a minute or so. The original position of the throttle body pushes the incoming air against the top where it is forced to each cylinder. Too much air or too little air can make your engine run lean.
Save money with our ultrasonic fuel injector service In modern fuel injected cars, the throttle body is an essential part of the air intake system, controlling the flow of air into the engine, which is used to effectively combust fuel in the pistons. Get an estimate for a throttle body replacement.
When the throttle body is in its appropriate condition, the engine receives an ideal air and fuel ratio and offers optimum performance. May 25, 2015 169 52 truck year 2015 jun 6, 2015 #2 ramman said: This pump supplies fuel pressure in sufficient volume to meet the engine's fuel requirement through all load conditions.
A throttle body service isn't a 'regular' maintenance as you would an oil change, i.e. Unfortunately dealerships, doctors, etc that you hope would be advisors are sales people. Fuel is delivered to the throttle body injection system by an electric fuel pump located in the fuel tank.
The throttle body service involves cleaning the throttle body with a special cleaning solution and removing carbon deposits from the throttle valve. Driving last week and the truck showed the service throttle control message and flashed a red bolt on the dash. When you step on the gas pedal, it sends a signal to the computer, which then sends a signal to a little electric motor in the throttle body.
When the throttle body is dirty. The throttle body is an important mechanical component found in fuel injected vehicles that controls and regulates the amount of air flowing into the engine. The throttle body is connected to the gas pedal of your vehicle with a linkage or flexible cable, which moves the throttle shaft when the gas pedal is depressed.
The throttle may operate properly at some times, but not at others. (if you're having difficulty locating the throttle body, ask a helper to press the accelerator, with the engine off, so you can see the movement of the throttle shaft.) The throttle body service is not very.
If your car is up there in the mileage or you start noticing certain issues it can help address them. As you can see, there are cables running to and from the sensor to complete the sensors circuit. You can use this simple formula from high performance math to determine an optimal size and compare to your current throttle body.
With drive by wire, we no longer need the iac system. By the late 1980s, most tbi systems were replaced with multiport injection (mpi) fuel injection systems. Getting the right amount of air is vital.
Throttle body injection systems were only used briefly during the 1980s as vehicle manufacturers moved from carburetors to fuel injection to meet u.s. Systems where the movement of the accelerator pedal translates into an electronic input signal to the engine computer, which then commands the electronic throttle body to open or close by a certain amount. A ported throttle body is intended to optimize air flow and promote air velocity which will provide benefits on any engine, but if the throttle body is too small, it will still be a choke point.
Heres how this method of operating the throttle works: A mechanical connection between the throttle and the accelerator is no longer present. If the diagnosis reveals a dirty throttle body as a potential cause of the problem, your mechanic may suggest the throttle body service.
The throttle body is the component of the air intake system that determines exactly how much air to let combine with the fuel. Over time, the inside of the throttle body. The accelerator position sensor sends a signal to your aveos pcm.
The throttle plate shaft is connected to a small motor and spring that responds to inputs from the computer. You can always diagnose both the sensor and its circuit with a scan tool. When the throttle body is working correctly, it.
Some people believe the incoming air is distributed to the cylinders better if you turn the throttle body clockwise so that the incoming air runs against the front of the intake manifold. The throttle body is a tube containing a pivoting flat valve (butterfly) that is used to control the amount of air entering an engine. In a traditional spark ignition gasoline engine, the throttle body is the part of the air intake system that controls the amount of air that flows into an engine's combustion chamber.
Which means that it uses sensors and actuators to control the throttle body. Sae certified mechanic and technical writer. It consists of a housing unit that contains a throttle plate (butterfly valve) that rotates on a shaft.
