5 Serious Throttle Problems

When problems begin with the motor, the driver, of course, begins to look for the causes of the malfunction. He checks many different components, even changes various parts, but all in vain. The AvtoVzglyad portal tells where to look for the weak link.

The cause of many problems can be a dirty or faulty throttle valve, because this assembly serves to control the air supply to the engine. It could also be a broken sensor. Below are five reasons why it can be judged that the throttle assembly requires attention, along with other machine systems, by the way.

Check Engine is on

The control lamp lights up when the engine control unit receives incorrect values ​​​​from the sensor. The problem can be checked by connecting a scanner to the machine. If in fact the throttle is open, and the scanner shows the opposite, this indicates a sensor failure. It is interesting that such a malfunction is wandering. That is, the emergency lamp may periodically go out, which will confuse the driver.

Difficult launch

Problems with the throttle clearly manifest themselves when the driver tries to start the engine after a long stop. The car starts with difficulty, and then the engine shakes until it reaches operating temperatures.

"Floating" turns

At idle and medium speeds, the tachometer needle begins to live its own life. This could be either a dirty idle speed sensor or a problem with the throttle. So we advise you to inspect both of these nodes.

Decreased engine power

If the car began to accelerate sluggishly, the motor responds lazily to pressing the gas pedal, then this is another sign of a broken throttle sensor.

Of course, the drop in power does not say unequivocally that the choke is the culprit of the trouble. There can be a whole "bouquet" of various "sores". But during repairs, this is an occasion to inspect this unit too.

Increased fuel consumption

Another indirect sign of problems with the throttle position sensor. However, if the engine has an appetite for fuel, we advise you to check the health of the sensor. The culprit of the problems may be the loss of contact on the "slider". The reason is the simple wear of the resistive layer, due to which the electrical contact disappears.

Finally, we note that such a common defect as throttle jamming can also become the cause of the problems noted above. It is provoked by high-temperature deposits that impair the mobility of the “curtain”. There is only one way out in such a situation - the use of special autochemistry. True, there are not many such drugs on the market.

Of the imported products, perhaps only the Pro-Line Drosselklappen-Reiniger aerosol, developed by Liqui Moly (Germany), can be distinguished. This product is intended for cleaning elements of the intake tract of gasoline engines. Its use allows you to get rid of a lot of problems. This is especially important for engines with a high compression ratio.

They often develop thick carbon deposits on the intake valves, which can only be removed with the Pro-Line Drosselklappen-Reiniger, which has a high penetrating effect. The drug quickly restores the mobility of the throttle, and without dismantling it. The aerosol itself contains a complex of detergent additives and special synthetic components that form an anti-friction film on the surfaces of parts. Such a coating slows down the process of subsequent sedimentation of carbon deposits in the intake tract. The drug is supplied in 400-gram cans, the capacity of which is enough for about 2-3 treatments.
