Field of activity and experience in this fieldIryna has over 5 years of experience in the selection and consulting of auto parts for both passenger and commercial vehicles. She is familiar with the specifics of most popular catalogs such as TecDoc, AutoData, and Elcats, as well as the principles of selection by VIN code. She has experience working with both B2B clients and end consumers. She understands issues like “equivalents don’t fit,” “part number changed,” or “urgent need — but it has to fit the first time.”
I know how frustrating it is when you need just one part, but there are five options — and you have to guess which one is right. My job is not to guess, but to get it exactly right. I don’t just look up numbers — I understand how the part works, what it connects to, and what happens if you get it wrong.

Speed Sensor: Operation Features, Faults, and Replacement
18.01.2024The speed sensor is one of many automotive sensors responsible for generating measurement signals, transmitting them, and ensuring their further processing by the ECU and other control units. Even in vehicles without an ECU, sensors remain essential. A failure of even the least critical sensor can affect the overall comfort of vehicle operation. Since the speed sensor is a fairly important component, let’s explore how it works, examine common malfunctions, and understand how even an inexperienced driver can replace it when necessary.
Alternator Voltage Regulator Relay: Structure, Functions, and Testing
13.08.2021The alternator voltage regulator relay — a complicated-sounding name for a relatively small component of a car or motorcycle alternator, whose failure can cause a wide range of issues. For example: undercharging or overcharging the battery. Such issues may have multiple causes, but in most cases, the problem lies with a faulty alternator relay (as it’s commonly called). Let’s take a closer look at what this component is, how it connects to the vehicle’s electrical system, how to test it, and how to replace it if necessary.
Idle Air Control Valve (Sensor): Design, Failures, and Choosing a Replacement
18.01.2024The idle air control valve, often referred to by drivers as the idle sensor, is one of the key components of modern engines. Its function sounds simple: to allow air to bypass the throttle and enter the intake manifold in order to maintain idle RPM within the designed limits. However, when you look closer at how it works and the common issues it may develop, it becomes clear that this small component is more sophisticated than it initially appears. Let’s dive into the details.
Steering Wheel Vibration: When It Happens and How to Fix It
18.01.2024Steering wheel vibration is the transfer of energy from the suspension and body of the vehicle to the steering mechanism. Normally, the steering wheel shouldn’t vibrate much, but when there is uneven load distribution on the wheels and suspension, the driver may experience shaking. The problem tends to get worse at higher speeds or when driving on rough roads. In practice, nearly all car owners have encountered steering wheel vibration. However, there are several distinct situations in which this issue may occur. Here’s what they are:
