The VAZ 2110 is equipped with a 1.5 and 1.6 liter injection engine. As you know, a large number of different sensors are used to operate the injector. Correct operation of the injector is achieved by accurate readings and frequency of the entire system. Often, VAZ 2110 owners are faced with the problem of floating idle speed; it is quite difficult to overcome such a reason without knowing the main reasons, and not everyone can afford to pay for expensive diagnostics.
After studying this article, you can easily find the reason for the floating idle speed on the VAZ 2110. All the reasons why the top ten does not maintain stable speed are described here in detail.
Floating or unstable idle speed on VAZ-2110, 2111 and 2112 main reasons
Today we will look at the main reasons why idle speeds fluctuate on the VAZ-2110, VAZ-2111 and VAZ-2112, the engine is unstable at idle .
One of the most common problems for owners of tens is to understand why the engine floats or does not idle. At the same time, the most unpleasant thing about this scourge is not that repairs require large financial costs to eliminate, but that there are a lot of reasons that, to one degree or another, can affect idle malfunctions on engines of the tenth family, and their search can be very labor-intensive and time-consuming work.
So, let's look at the main ones. The first and most common cause of floating idle speed is a malfunction of the mass air flow sensor (MAF). You can check the mass air flow sensor using the method described in this article - What is a mass air flow sensor and how to check the mass air flow sensor for a malfunction?
It would also be useful to check the serviceability of the idle air control - see what it looks like and where it is located in 2110, see the photo below.
Another sensor that has problems with idle speed and not only is the crankshaft position sensor (CPS). If it fails completely, the car will not start at all, but if there are bad contacts in the sensor area (and this is a common problem), such symptoms are quite possible.
The sensor itself is quite reliable; carefully inspect the wiring around it. It also wouldn’t hurt to check the entire intake system for air leaks (including the vacuum seal). Be sure to thoroughly clean the throttle body on your vehicle.
At the same time, check the TPS (throttle position sensor). It should also be noted that many people do not pay attention to the condition of their high-voltage spark plug wires. Sometimes in the dark you can observe some kind of “Tesla” effect under the hood. Well, I hope that no one forgot to check the condition of the spark plugs. After all, spark plugs also require periodic replacement and maintenance, especially with our fuel quality.
By the way, do not forget about such basic things as the condition of the air filter - if it is clogged, then you are guaranteed problems with the normal operation of the engine. After all, he is directly involved in mixture formation, and many simply forget about it. We hope that our small manual will help you find and eliminate problems with idling on your car of the tenth VAZ family
