The accelerator pedal is a control element for the throttle and its valve. The function of the throttle is to regulate the amount of air; the more air, the higher the revolutions of the engine's crankshaft. Depending on the car model, different designs of accelerator pedals can be installed.
- A mechanical gas pedal is a pedal whose throttle is driven through a cable or lever connection. All this significantly reduces the effort required to press the gas.
- An electronic gas pedal is a pedal whose operating principle of an electronic unit is more complex, but in this way the process of controlling speed becomes easier. The electronic accelerator is used only on engines with an injection power system. Its device is completely electronic. It is based on electronic modules that convert electrical signals.
Signs under which the driver needs to contact a service center for diagnostics and repair of the malfunction.
- Difficulty pressing the accelerator pedal or its sticking.
- The pedal does not return to its original position on its own after being released.
- Absence or uneven response of the engine to pressing the accelerator pedal.
- Creak when pressed.
- Requires more or less force to press
- Increased fuel consumption and difficulties in acceleration.
Before replacing the accelerator pedal, it is necessary to perform diagnostics and, if possible, adjust the drive. If the malfunction symptoms are not resolved, then proceed with repair or replacement of the Accelerator pedal. Repair work begins with the removal of the pedal. If you have an electronic pedal, it is disassembled for repair; if it cannot be repaired, it should be replaced with a new one. After removing the old pedal, install a new one and after installation, for a mechanical pedal, the accelerator cable is connected, for an electronic pedal, electrical connections are connected.
After installing the new pedal, diagnostics are performed. Diagnostics are carried out to ensure that the new pedal moves freely and returns correctly to its original position, and in the case of an electronic pedal, it will be necessary to adjust the programming of the engine management system and check that the pedal is correctly synchronized with the vehicle's power system.
