The throttle cable (gas cable) is the connecting link between the gas pedal and the throttle; when you press the pedal, you do not act on the cable, which in turn opens/closes the throttle valve. This way you regulate the flow of fuel to the cylinders, as well as the engine speed and vehicle speed.
A poor (untimely, delayed) response to pressing the gas pedal is most often a sign of problems with the throttle cable. The problem may lie in the fact that the throttle cable is incorrectly adjusted, its tension has weakened, in addition, the throttle cable may have stretched or completely failed and requires immediate replacement. If, when pressing the gas pedal, you feel resistance similar to friction, or pressing the pedal has become hard and not smooth, you need to lubricate the cable.
In this article I will talk about how to adjust the throttle cable, as well as how to lubricate the gas cable on a Lada Priora at home.
Attention! Before adjusting the throttle cable, make sure that the tight movement is not due to the carpet or other obstructions that may interfere with the free movement of the gas pedal. Very often, because of this banal “breakdown,” drivers make a lot of unnecessary movements and dismantle the engine almost to the ground in search of the reasons for the lack of engine power. As a result, it turns out that the new mat is simply bent or slipped somewhere and the pedal moves only half its travel.
Lubricating the throttle cable on a Priora at home
To work you will need:
- Flat screwdriver;
- Pliers;
- A syringe and a few drops of motor oil or WD-40.
Actually the work itself.
1. First you need to turn off the engine and let it cool.
2. Next, you need to open the hood and remove the decorative engine cover.
3. To remove the throttle cable, you need to remove it from the plastic bracket; to do this, pull the cable casing towards you and, pushing the rubber ring up, remove the cable.
4. Now you need to disconnect the cable from the throttle valve drive. To do this, remove the U-shaped metal bracket from the throttle actuator by prying off one edge using a flathead screwdriver.
5. We remove the cable from the hook, overcoming the force of the spring.
6. Now that nothing is in the way, you can begin to lubricate the throttle valve actuator; to do this, you need to slide the transparent cap and generously lubricate the cable with a few drops of engine oil or WD-40 penetrating fluid. In the case of oil, prepare a syringe.
Try to pour oil into the housing, then move the housing to lubricate the cable along its entire length. Repeat the procedure several times until the cable is completely lubricated.
Next, put the protective cap back in place and reinstall the cable to the place of further service.
Correct adjustment of the throttle stroke
At its core, throttle free play is the position of the stick from the moment the throttle valve is closed to the moment it begins to move. It is important to know that this figure should be in the range from 2 to 6 mm.
Let's figure out what happens if there is no free play of the throttle at all:
1) Firstly, it is difficult to adjust the idle speed. It is possible that the throttle cable is too tight and the throttle is slightly raised. At the same time, the engine speed is increased, and we think that the whole problem is the inability to adjust the idle speed, we are looking for problems in the carburetor, etc. 2) Secondly, if the cable is pulled higher than normal, the scooter can simply move off on its own (simulating turning the throttle), then there is no question of any idle adjustment at all. 3) Thirdly, throttle control becomes uninformative at low speeds, there are problems during stopping, and moreover, a complete stop can only be achieved by turning off the ignition.
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 throttle valve is not open when the gas pedal is at zero position. A cable that is too tight will cause the idle speed to be constantly elevated. 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.
NOTE Adjustment of the throttle valve drive is shown on the VAZ 21124 (1.6i) engine. Features of adjusting the throttle valve drive on the VAZ 2112 (1.5i) engine are indicated in the text.
RECOMMENDATION It is necessary to adjust the throttle valve drive after replacing the drive cable, after removing and installing the throttle assembly, and also after performing work related to dismantling the intake module. Throttle actuator adjustment may be necessary if the vehicle's engine may not be able to produce maximum power due to the throttle valve not being fully opened.
An assistant will be required to perform the adjustment work. Adjustment sequence
1. We prepare the car for work (see paragraph 2a Preparing the car for maintenance and repair).
2. Remove the decorative trim of the engine (see Decorative trim of the engine - removal and installation). 3. After loosening the three clamps, remove the air supply hose to the throttle valve. 4. We control the position of the throttle valve: with the gas pedal pressed (all the way to the floor), the valve should be completely open,... .
and when the gas pedal is released, it is completely closed. 5. The position of the closed throttle valve is adjusted with a stop screw, rotating it with a slotted screwdriver with a thin blade. The throttle valve should close completely without sticking. The position of the open throttle valve is adjusted by changing the tension of its drive cable.
WARNING When adjusting the open throttle valve, do not overtighten the cable, as this may damage the drive elements.
6. On the VAZ 2112 (1.5i) injection engine:
Using two 13 mm wrenches, rotating the adjusting nuts (1 and 2), we adjust the cable tension (small sagging of the cable is allowed in the area between the throttle valve drive sector and the end of the casing).
On the VAZ 21124 (l.6i) injection engine:
a) Use pliers to remove the locking plate of the cable sheath. b) By moving the cable sheath in the rubber holder, we adjust the cable tension (in the area between the throttle valve drive sector and the end of the sheath, a slight slack in the cable is allowed). c) Install the locking plate in place. 7. Check the operation of the throttle valve drive. If necessary, repeat the adjustment. 8. Install all the removed parts on the car in the reverse order of removal.

When to tighten and when to change?
During operation of the machine, the steel cable gradually stretches and begins to sag. Then part of the lever stroke is used to remove this slack (the first 2-3 clicks), and only then the force is transferred to the brake pads of the rear wheels. As a result, they are weakly pressed against the surface of the discs or drums and the car does not brake reliably.
But the operation of the mechanism also depends on other factors:
Abrasion of the linings does not have much effect on the operation of the main system, since the stroke of the hydraulic pistons is quite large. But the effect of the mechanical “handbrake” gradually weakens. To return it to working condition, it is necessary to compensate for the wear of the elements by tensioning the drive. If the cable itself is in satisfactory condition, the extension of the tension pin will be enough to ensure the operation of the parking brake at any degree of wear on the linings.
The cable is replaced in the following situations:
Cable jamming also occurs in winter, when water trapped under the casing freezes inside. In this situation, do not rush to change it; first warm up the car in the garage, and then drive out the moisture using WD-40 aerosol lubricant.
How to install the cable?
I will tell you how to replace the throttle cable on a VAZ 2110. To do this, you need a screwdriver (flat), a new cable, side cutters and pliers with flat jaws. First of all, remove the plastic engine protection. Then remove the safety bracket from the throttle assembly sector, prying it off with a screwdriver. Then we pull the cable tip out of the groove and disconnect the cable. Then remove the spring stopper using pliers (Figure 3).
And we pull out our cable from the slots of the holder (Fig. 4). We cut through the plastic clamp that tightly clamped our cable to the gas ventilation hose (Fig. 5). Next, we move the cable sheath forward (Fig. 6). We take out the cable sheath damper from the front end (Fig. 7). Disconnect the cable in the cabin under the gas pedal (Fig. 
That's it, now we can pull out the cable and replace it with a new one, doing all the operations in reverse order. Do not forget to secure the cable to the gas ventilation hose with a plastic clamp.
The last step in tuning is adjusting the throttle.
Throttle valve adjustment:
1. We loosen clamps at the connections of the intake pipe (1) and the throttle body, as well as at the junction of the large crankcase ventilation hose and the fitting (2), which is located on the cylinder head cover.
2. With the gas pedal fully depressed, the throttle should be in the fully open position. (For this action you will need the help of a partner).
3. When the gas pedal is fully released, the throttle valve should be in the fully closed position.
4. If steps 2 and 3 are not followed, the throttle cable needs adjustment.
5. If, when checking the adjustment, it is revealed that the damper does not open completely, then you should loosen the nut on the bracket, the second one from the end of the cable, and tighten the first nut until the desired effect is achieved.
6. If the throttle valve does not close completely, then do the opposite, namely, loosen the first nut from the end of the cable and tighten the second nut.
When you achieve full opening and closing of the partition when pressing and releasing the accelerator pedal, you have adjusted the throttle cable.

How to change the throttle cable on a VAZ-2110 injector
Every little detail in a car is important, even something like the throttle cable. The functionality of the entire vehicle mechanism depends on its high-quality work.
- Clamps are used at the connections of the intake pipe and throttle body, at the junction of the hose of the huge crankcase ventilation circle and the fitting located on the cylinder head cover.
- of the throttle valve
is checked (the help of a partner will be useful for this purpose): - when the accelerator pedal is completely recessed, it is completely open;
- when the accelerator pedal is released one hundred percent, it is one hundred percent closed.
If, as a result of the check, it is revealed that the throttle valve does not open to its fullest extent, then it is necessary to loosen the nut on the bracket, the second one from the end of the cable and tighten the first nut. If the throttle valve does not lock in all cases, under such circumstances, you should loosen the first nut from the end of the cable and tighten the second nut.
Electronic gas pedal - how does it work?
Modern technologies are aimed at making our lives as easy as possible. On the one hand, this is a huge plus, but on the other hand, they simply deprive us of the opportunity to make any decision, or rather, they correct it, and in such a way that it is not always possible to achieve the desired result. This is clearly visible in the operation of the electronic pedal, which is so popular in the modern automotive industry. Although for those who feel insecure behind the wheel, and especially do not delve into the technical nuances of the car, this innovation is only a plus.
The principle of operation of the electronic gas pedal is as follows: after the driver presses the accelerator, data on pressure angles immediately enters the control unit through special sensors. Next, the ECU comes into play , which calculates the required opening angle, and the drive, based on the data received, opens it to this angle
. Moreover, if it suddenly becomes necessary to change the value of this angle (for a more economical mode or safety), the control unit does it itself, without receiving the corresponding command. It turns out that the driver cannot 100% regulate this process.
Why and when do you change the clutch cable on a Logan?
Intensive use of a vehicle inevitably leads to wear and tear on the components. The signal that the cable needs to be changed is the appearance of squeaks in the clutch pedal. The sound is especially clear in hot weather, after a long trip. There can be several reasons for a squeak:
- The clutch cable has reached its required service life and needs to be replaced.
- The pedal stop is very dirty and requires cleaning and lubrication.
- The release bearing has failed
- The basket is worn out.
The resource of the element depends on the intensity of driving, as well as on the quality of the spare part. Replacement is an inexpensive procedure and no special tools are needed. Compared to other typical operations, such as replacing the end, installing a new cable is faster.
Replacement Tools
To work you will need:
- The key is "8".
- Two keys for "14".
- Screwdriver (phillips).
Sequence of work
For comparison, old and new clutch cables
They go in this order:
- Move the air filter housing to the side.
The air filter housing will interfere with us, so we will move it to the side. Moreover, all the housing latches were broken and it was dangling under the hood

Important! Before installing the cable, you need to adjust the clutch pedal so that it is 10-13 centimeters from the floor level. We have already written in more detail about replacing the clutch itself on a VAZ-2112.
Video about replacing the clutch cable
Clutch adjustment on a VAZ-2112
During clutch adjustment
To adjust, you will need to rotate the bolt, which is located on the cable on the gearbox side. When the pedal distance is adjusted, tighten the nut and press the pedal 2-3 times. If all is well, then tighten the locknut on the casing. Next, the car is assembled in the reverse order.
The clutch cable must first be lubricated with LSC-15 or Litol-24.
