The trend of recent years in the automotive industry is the gradual removal of the driver from the process of driving. Designers and marketers have not yet reached the point of losing the connection between arms and legs with turning wheels and braking, but everything is moving towards this. Not a single modern car is supplied to the market without an electronic throttle and an electronic accelerator.
Electronics are reliable things, but sometimes they fail.
The design and principle of operation of the electronic gas pedal
To understand how it works and functions, you need to roughly understand the general circuit of the mechanical analogue. The functions of these systems are similar, but the simplest unit can only be considered a traditional drive.
The gas pedal is a control element for the throttle and its damper. The function of the throttle is to regulate the amount of air. The more air, the higher the engine speed the crankshaft will rotate. The pedal is connected to the throttle drive via a cable drive or levers. All this significantly reduces the effort required to press the gas.
The operating principle of the electronic unit is more complex, but this makes the process of controlling speed 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.
What does the accelerator pedal position sensor do?
In essence, the accelerator pedal is responsible for the amount of fuel entering the engine cylinders. With its help, the shaft rotation speed is also regulated, thanks to which the overall speed of the car and its power are regulated. If we translate the accelerator in the literal sense, then it is an accelerator. Every time the driver presses the pedal, the valves responsible for supplying fuel open more.
It is important to consider what role the accelerator and the control sensor connected to it play in the process of accelerating the car. It should be understood that there is a direct relationship between the engine, or, as it is also called, the heart of the car and the gas pedal.
Using the sensor, the amount of fuel supplied is monitored under various conditions in order to select the optimal amount in a given situation. This allows you not only to monitor, but also to correctly manage this process, as well as the process of engine operation at idle.
In addition, thanks to the accelerator pedal position sensor, a smooth transition of each action is ensured, which significantly reduces jerking of the car and increases the safety of its operation.
In vehicles equipped with an automatic transmission, the role of this sensor expands somewhat. It also provides sharp acceleration of the car when this should be done from a lower gear.
• install special sensors in the extreme position;
• provide an assessment of the degree of change in the sensor resistance;
• provide the possibility of influencing the rigid element of the pedal.
It should be taken into account that the design of sensors is constantly being improved, which allows for increased functionality for monitoring and controlling the engine. The latest achievements in the field of electronics, programming, and modern scientific developments are being actively implemented.
In fact, in addition to the control system, this part also includes feedback from the driver. For example, vibration of the pedal is introduced at certain stages of pressing, or the force for pressing it in a certain position is increased.
Symptoms of a problem
Among the main signs of problems are:
- Absence of any reaction to the accelerator after starting the vehicle’s internal combustion engine;
- Dips, loss of throttle response while driving;
- Floating idle speed;
- Sharp jumps in speed when you gently press the accelerator;
- Idle speed too high.
The device contains movable electrical contacts, as well as conductive tracks - these elements are subject to wear during operation. In the operation of the engine, you can observe dips when picking up speed, unstable idling.

If there is a malfunction in the unit, the driver can see this by a warning light on the dashboard. In such a situation, the ECU will switch the engine to standby mode.
In this mode, you can observe a slow increase in speed, even if you press the accelerator sharply. In addition, the vehicle's fuel consumption may increase significantly.
If two sensors in a unit fail at once, the ECU will switch the operation of the internal combustion engine to emergency mode - the driver will not be able to influence the operation of the engine, the speed under any conditions will be slightly higher than the idle speed.

Examination
If the device has potentiometers, then they are checked with an ordinary multimeter. It is necessary to use the electrical diagram of a specific vehicle. To avoid having to remove the entire assembly, the resistance can be controlled from the ECU.
To check, you will need knowledge of the ECU pinout and the resistance level of the potentiometer in different pedal positions.
If the pedal is digital, then checking it is only possible with computer diagnostic systems.
Repair
If there are any problems with the pedal, then only a complete replacement of the unit will help. But before changing anything, it is worth identifying the cause of the malfunction. To do this, you can use a multimeter test.
You can disconnect the sensors and the block and remove the pedal. Check the resistance - when you press the gas it should change slowly. Jumps in indicators indicate malfunctions.
But sometimes repairs are possible - for example, the wiring is damaged. If a wiring defect is detected, you can use the following diagram.
- Release the axis on which the gear is attached.
- Remove the wiring harness.
- Then the wires are soldered off.
- Release the bracket and pull out the cable.
Next, change the wires and solder them according to the connector under the pedal.

Adjustment
The adjustment process may vary on different car models, since different manufacturers use mechanisms of different designs. But the same principle can be applied for configuration. As for a specific model, it is better to find information on it in advance.
To begin the adjustment, the first step is to remove the pedal from the holding bracket. Next, loosen the screws securing the cover. One screw holds the cover in a certain position - it must be completely unscrewed. The cover is turned to the side clockwise until the end, then the screws are tightened again.

This adjustment will reduce pedal response time. Some car owners note that after such adjustments, the response speed can even be compared with a mechanical pedal. Adjustment allows you to improve engine performance and improve the start of movement from a standstill.
In cases where a pedal with low sensitivity is needed, it is necessary to rotate the cover in the opposite direction - counterclockwise. The machine begins to respond to presses not so quickly.
Sometimes you can come across harmful adjustment tips - drivers advise placing shims under the lever. This is the wrong approach. Sometimes the pads get caught under the contact pads in the potentiometer, and the machine may lose control as a result.
How to adjust the throttle cable of a Lada Priora?
- The adjustment is carried out using a clamping bracket, which we previously removed. This bracket is a tensioner for the casing in which the cable moves.
- Remove the bracket and tighten the throttle cable so that it sags about 1-2 mm near the throttle drive.
- Now you need to install the fixing bracket into place in the casing. Make sure that the cable is tensioned optimally and that the gas pedal is not open at zero position. A cable that is too tight will cause constant high voltage. Squeeze the gas pedal several times and check how everything works.
- Start the engine and make sure the throttle cable is adjusted correctly and the idle speed is normal.
Remarkableness of the cable drive
Such a drive is installed exclusively in carburetor fuel injection systems, where the dosage of the mixture before it is supplied to the cylinder is carried out mechanically.
It is worth noting that in the era of carburetors there were no electronic fuel control systems yet; everything was done by pressing the accelerator, which was connected via a flexible steel cable to the throttle valve.
The position of the gas pedal determines the opening of the damper, respectively, the speed of the power unit, its power and speed gain while driving.
In principle, the carburetor system is quite stable in operation. However, it has one significant drawback, which is fuel supply failure at sub-zero temperatures.
Starting a power unit in winter turns into a kind of test, since it is quite problematic to determine the correct formation of the fuel mixture and select the required ignition timing.
If you overdo it with the suction, the spark plugs will immediately flood with fuel. Similar inconveniences occurred on all transport equipment equipped with carburetors.
Noise when braking
High-frequency noise, squealing, and whistling can occur both during braking and, sometimes, during normal movement. The reason is the off-design mode of friction of the friction material on the working surface of the brake disc. Extreme wear on the brake pads and severe corrosion of the brake disc (often on the inside, “invisible” side) may be to blame. It happens that the brake pad lining has peeled off from the base. The list of possible causes continues with contamination of the pads, warping of the disc due to local overheating, improper fastening of the pads in the caliper, left pads or discs, etc.

After installing JETTER
, your car will move to a whole new level of driving. He will become more aggressive, faster, and more maneuverable. The throttle response speed will increase significantly, providing lightning-fast acceleration without dips. It doesn’t matter: you are climbing to the top of a mountain, performing an active overtaking or other maneuver, the jeter will give you a feeling of freedom and comfort throughout the entire journey.
JETTER
will reveal the true character of your car. You will not let go of the feeling that there is a powerful turbocharged engine under the hood. And the exciting start will be appreciated not only by you, but also by those who remain behind you.
WITH JETTER
you will be able to change gears literally in a split second, and this will not affect the behavior of your car in any way. When accelerating, the average delay time in 3rd and 4th gears is practically reduced to zero, as a result, acceleration is smooth, without pause, like in a good automatic transmission. You will fall in love with your car again, feeling its powerful drive and rapid acceleration, getting the most vivid driving experience on any bend.
The car pulls to the side
It is clear that not only the brakes can be to blame for a car drifting off course - the wheel alignment angles, the wheels themselves, and the steering can also be to blame. However, quite often questions arise specifically about the brakes, especially if the car pulls sideways when braking. Most often, jammed pistons in the cylinders of one of the circuits are to blame. It is possible that the wheel may brake due to the loosening of the bolts securing the pad guide to the steering knuckle, as well as the pads getting oily or getting brake fluid on them.
Perhaps an ice or salt crust has formed on the surface of the pads, or the pads are simply wet. Or one of the circuits of the brake system does not work - the pedal is low and the braking efficiency is low. Brake disc runout, wheel bearing wear, and brake drum out-of-roundness may also be to blame.
