In order to determine the extent and speed of the choker a special throttle sensor is used. This sensor is one of the measurers of the electronic control systems for vehicles with fuel injection. The throttle sensor is located on the opposite side of the throttle control lever on almost all cars. Such a sensor has several outputs: to one is applied voltage, the second is connected to the mass, and the third emits a signal to the engine control unit.

When the throttle is closed, the resistance and voltage on the sensor are minimal. But when the throttle opens, the tension gradually increases and reaches the maximum, about 5 V in the final position. Based on the signals from the throttle sensor, the engine control unit estimates the vehicle speed and the degree of baffler opening and thus corrects the time and the amount of fuel injected at the time of ignition.

The absence of signal indicates a malfunction of the throttle sensor. But the damage can also be detected by other external signs: difficulty starting the engine, high idle speed, interruptions during acceleration and increased fuel consumption.

You do not have time for shopping car parts? Or maybe, you consider yourself a beginner in this field? Repair in service centers is a lot more expensive, and replacement of parts will probably take longer than you think? So, you definitely need to go to our online store. You can do it from your home or office. All you need is to select a baffler sensor compatible with your vehicle. We will deliver your order in a short time and to any convenient place. Apart from throttle sensor, you can also buy tie rod ends, parking brake system drive wire, radiator grille, as well as fuel level sensor.

What you need to know about throttle position sensor replacement: lifetime limits, common defects and their signs, tips and recommendations

The throttle position sensor doesn’t have a specified service life. Most often it breaks down as a result of slider wear-out. Moreover, another cause for TPS replacement is abrasion of the resistive layer of strips along which the slider is moving, especially in the sector where it starts moving.

Main signs of a throttle sensor breakdown are the following: increased fuel consumption, too high engine idle rpm, troubled engine start. Moreover, the engine can stall at idle.

The throttle valve position sensor condition should be assessed at a service station. The thing is, inspection of the component can have specific features depending on a car model. More often specialists perform computerized diagnostics.

You should also address to a service station for a sensor replacement. Incorrect component installation can cause throttle valve failure.
