How should the throttle cable be tensioned

I once saw a post on the tape about the tension of the throttle cable. I decided to try it myself.

So, we remove the decorative plate and see this picture.

We see a cable going to the throttle valve. By default, the bracket on the cable was set to the 8th division. The cable itself is slightly loosened; the throttle regulator rests against the throttle body with its limiter.

We take out the cable with the rubber band that holds it in place and remove the metal. bracket, put back the cable with the rubber band and pull the cable to the right until we feel the free movement end and the throttle valve begins to open. We put the bracket back.

It turned out that free play is selected at the 11-12th division. (you can see in photo 3 that the damper regulator no longer rests against the body with the limiter, but moves away by 3-4mm). This way we create a light preload. As a result, free play is removed from the gas pedal. And even with a slight touch of the gas pedal, the throttle valve is immediately actuated, which improves reaction time and responsiveness to the gas pedal.

I haven't driven much yet, about 20 km. But the impressions are only positive. It became easier to get underway, immediate response to the gas pedal, more predictable reaction. I really liked it. I regret that I didn’t do it earlier))

I'll keep watching for now. But today, perhaps due to the heat, the injection was slightly increased by 14-25%. (consumption at idle = 0.8-0.9 l/h) Usually this figure is around 2-5% injection and 0.7-0.8 l/h consumption at idle. But the revs didn't increase. For now I'll chalk it up to the heat.

At the same time I looked at the recently replaced valve cover gasket. Everything is fine, dry).

The design of the gas pedal is practically no different from the clutch pedal; time does its job with the gas pedal. After a certain period of time, the pedal begins to work incorrectly, pressing on the gas we have to press the pedal to the floor for anything to happen, or vice versa, the pedal travel is too small and as soon as we touch the gas pedal, a rapid increase in speed begins. Both options are very inconvenient for us, because we are accustomed to something in between. This makes it easier to drive a car in a style that has already been developed over the years. After all, regardless of the factory, the pedal travel in all cars is different, even if you compare 2 absolutely identical cars, their control will be different. Therefore, drivers who are accustomed to driving in the same style and with the same sensitivity of the car want to preserve this feeling and transfer it with it to another car.

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.

How to replace the throttle cable on a VAZ-2110 step by step instructions

You can carry out the procedure for replacing the gas cable yourself, and for its subsequent adjustment you will need a partner who will press the gas pedal.

This procedure is carried out only when the engine is cold. Otherwise, there is a risk of burns during cable replacement work.

To correctly replace this cable on a VAZ-2110, you need to follow the following step-by-step instructions:

Prepare the necessary tools:
pliers – large and thin.
Dismantle the throttle valve cable:
use a screwdriver to disconnect the crankcase gas ventilation hose;
the locking spring holding the sector is removed;
the main part is removed from the groove by hand when turning the sector counterclockwise;
the cable is disconnected from the throttle assembly.
Removing the cable from the bracket:
for 8-valve cars - loosen the nut, move the rubber cover, remove the middle part of the cable from the bracket;
the cable itself is pulled through a plastic clamp, which is pre-cut.
Removing the cable from the vehicle interior:
Removing it from the engine compartment (simply pulls it out of the cabin).
Installing a new part:
one edge is pushed into the cabin and connected to the gas pedal;
the second edge is attached to the throttle valve.

After completing the procedure for replacing the throttle cable, it must be adjusted:

Clamps are used at the connections of the intake pipe and throttle body, at the junction of the hose of the large crankcase ventilation circle and the fitting located on the cylinder head cover.
The operation of the throttle valve is checked (for this you will need the help of a partner):
When the gas pedal is fully released, it is completely closed.

If the test reveals that the throttle valve does not open fully, then you need 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 close completely, then loosen the first nut from the end of the cable and tighten the second nut.

Adjustment of the VAZ-2110 throttle cable is considered complete when the throttle is fully functional when the accelerator pedal is pressed and released.

Throttle adjustment

To make adjustments, we only need pliers. When starting adjustments, first remove the plastic engine casing. Next, disconnect the air supply hose from the throttle body pipe. Then the assistant fully presses the gas pedal to the floor, in this position the throttle valve should be fully open. Accordingly, when the pedal is lowered, the throttle valve should be completely closed.

In other cases, the throttle valve needs to be adjusted. To adjust, remove the spring stop (Fig. 3). Move the cable sheath (1) and adjust the free play of the cable. When we finish this operation, install the stopper tightly to the rubber bushing (2) (Fig. 4).

This completes all gas pedal settings.

Note! A lot of engines were installed on cars of the tenth family, ranging from carburetor 1.5 to injection 16 valve engines. Let us immediately warn you that carburetor engines from the Samara family were installed on dozens, and we already have information on adjusting all the valves on carburetor Samaras and it is posted in two article, the first is called: “Adjusting the throttle valves”, the second: “Adjusting the air damper”, so if you have a carburetor, then go straight to them, because in this article we are talking only about injection cars and we will not touch on carburetor cars!

1) Let’s write briefly because there is nothing complicated in the adjustment, and there are not many nuances, in general, let’s start with the throttle valve closed (This is when the gas pedal is released and nothing presses on it), so if it is not completely closed, then the adjustment it can be done using a cable, but it is not always possible to adjust the position of the closed damper with a cable, so the adjusting screw comes into play, which is located on the throttle assembly itself (see photo 1), you will either need to tighten it, or, on the contrary, loosen it a little, thereby achieving a completely closed damper (And it shouldn’t jam yet, keep this in mind), but you need to be careful with this screw, if you tighten it too much, the car will simply stall or won’t start at all, and if you unscrew it too much, the idle speed will increase, fuel consumption will be the same and the throttle will be slightly open, but the easiest way is to adjust it by speed, for example, on a warm engine, your idle used to be 800 rpm, you will need to start the car, warm it up in the same way and adjust this screw so that again there were 800 revolutions on the tachometer needle as before, we’re done with adjusting the damper, proceed to adjusting the cable on 8 valve cars, look for the place where the cable connects to the bracket (see. photo 2), once you have found it, take two wrenches and rotate the adjusting nuts (Nut 1 and 2) with them, adjust the cable as you need (It is allowed to sag a little, do not tighten the cable too much), 16 valve cars are also adjusted in the same way , there a metal plate is pulled out with pliers or by hand (see photo 3) and after which the cable is adjusted by moving it (To the back and to the front, see photo 4), as soon as the tension suits you (Remember, do not overtighten it ) the plate is inserted into its place and the adjustment is complete; at the end, check whether the throttle valve opens completely when the pedal is pressed all the way and whether it closes.

Note! Let's say a few words about the adjusting screw, the most important thing is not to confuse it with any other screws (For example, with screws A, by the way, they cannot be turned out at all), it stands on the side, for clarity, in the photo below it is indicated by an arrow with the letter B!

Additional video: Using the example of a Renault Logan car, look at how the cable is adjusted, it applies to 16 valve cars; on dozens with a 124 engine, this adjustment is done almost exactly the same way.

Note!" And regarding 8-valve machines, see the cable adjustment a little lower; by the way, it also applies to some 16-valve machines (If the intake manifold is not plastic, but aluminum)!

Throttle cable

The intermediate link between the accelerator pedal and the throttle valve is a cable. It is the correct tension of the throttle drive cable that allows you to get maximum power from the engine and its stable operation at idle. After all, weak cable tension can cause the throttle valve not to open fully and, accordingly, the engine will not develop maximum power. A overtightened cable can cause even more problems. Indeed, in such a situation, the throttle valve may not close completely and suck air into the manifold, increasing engine speed. But this is not the worst thing. The fact is that the ECU judges engine load largely by relying on sensors in the throttle valve. These sensors are the throttle position sensor and the throttle valve closing sensor. The latter is a simple electrical contact.

Namely, when the cable is adjusted correctly, when the gas pedal is released, the valve closes as much as possible, closing the contacts, which in turn gives the ECU a command to close the throttle valve. The ECU switches the engine to idle mode.

Incorrect throttle cable adjustment

If the overtightened cable prevents the contacts from closing, then the ECU will never know that the driver has released the gas pedal all the way and will control the engine in partial load mode rather than idling.

Lacetti ECU sensor diagram

For several years now, either dying down or flaring up again with renewed vigor, the topic of tensioning the Lacetti gas pedal cable has been circulating on the Internet. Its essence is that if you tighten the cable, the car stops twitching when changing gears, etc.

Having read this, inexperienced car enthusiasts immediately run to pull the cable tighter. They tighten it and problems begin with engine speed, the position of the throttle lock at idle, and the like.

The cable tension must be strictly monitored. But this must be done correctly and without fanaticism.

Adjusting the Lacetti throttle cable

The only tool you need is a 10mm socket wrench to remove the engine trim. I don’t think there’s any need to tell you how to remove it.

Here we see such a picture

To tighten the throttle control cable, you need to remove this clamp

It can be easily removed with bare hands

After this, pull the cable casing to the right until the sagging of the cable becomes minimal and insert the lock back. In this case, the cable was stretched four notches. The arrow shows its previous position

If the cable is adjusted correctly, then when you press the gas pedal, the throttle should open completely, and when released, it should close completely. Moreover, there must be a gap in this place for the smooth operation of the IAC, since on the Lacetti 1.4 and 1.6, the IAC directly controls the throttle valve.

Attention! This gap is not constant and depends on whether the ignition is on or off, as well as on the temperature of the coolant when the ignition is on or the engine is running! Therefore, there is no need to adjust this gap!

And you need to make sure that when you release the gas pedal, the shoulder at the back rests against its stop. Then the gap will be normal.

Therefore, it is necessary to check the adjustment not by the sag of the cable, but by the fit of the collar! Do not pull on the cable to remove any slack! Make sure that the shoulder rests against its stop and then give the pedals 2-3 mm of free play. There must be free movement. This way you will eliminate the influence of the cable on the operation of the IAC!

We start the engine and check the operation of the drive and watch the idle speed. They should remain at the same level. If they have increased, it means the cable is overtightened.

You can also look at the adequate response of opening/closing the damper in the Chevrolet Explorer program

Throttle flushing tens

Often, VAZ 2110 owners confuse a malfunction of the throttle assembly with an ordinary clogged valve. The main symptoms of the latter include:

when you release the gas pedal, the engine does not immediately switch to low speed;
the engine is difficult to start in severe frost;
after starting, the engine vibrates for a few minutes;
The engine jerks regularly at low crankshaft speeds.

To clean the throttle valve. Carefully remove the plastic decorative trim that covers the top of the engine. Next, disconnect the ventilation system hose and drain the oil from the air pipe. After this, unscrew the cap from the expansion tank and disconnect the fuel tank ventilation hose. Having done this work, we get free access to the throttle valve of the “tens”.

The part itself must be cleaned using aerosol products such as Wynn's or WD-40. The procedure for washing the part should be repeated with a short pause of 15 minutes. At the first stage, we treat the part with an aerosol and wipe it with a damp cloth. The second time, an aerosol is also needed, only you need to wipe the part with a dry piece of cloth. During the cleaning process, it is strictly forbidden to use brushes for working with metal, as they severely damage the surface of the throttle assembly.

When cleaning the throttle valve, you should also pay great attention to the crankcase ventilation duct. This part of the assembly is most susceptible to contamination

To wash the internal channels of the damper itself, unscrew the idle speed sensor. If you find play during the process of dismantling the sensor, then the part should be replaced

You also need to pay attention to the condition of the gasket in the throttle assembly. It's best if you replace it too
