What Does a Stalling Engine Mean?

Of all the components of a vehicle, one of the most complicated aspects is the engine, especially on modern vehicles, which are built with a variety of both mechanical and electrical solutions. When the engine stalls, something is terribly wrong with the health of the engine, and now it is presenting a danger to both the driver and the rest of the vehicle. For this reason, it is highly important to make sure that your engine gets taken care of, as soon as possible. To fix the problem, though, you need an idea of what the problem is. Here are some different things that a stalling engine could mean, usually…

Bad sensors

The most common reason that engines stall, nowadays, is because an electronic sensor within the vehicle is unable to register, which shuts the entire system down. For example, a camshaft sensor helps determine which cylinder in the engine is firing so that the fuel injector can match up to it. When this sensor stops working, the engine cannot function, and so it stalls. Most modern vehicles are entirely dependent on these electronic sensors, so usually a newer car’s engine will stall for this reason.

A leaky vacuum system

Another component that most modern vehicles utilize is an engine vacuum system, which helps supply information to the vehicle’s central computer so that the driver can be alerted when something goes wrong. When there is a leak in one of these vacuum lines, or if one of the lines becomes disconnected, then it can send a signal to your vehicle that it is unsafe to drive, which can lead to the engine stalling. You can tell if your car has a leak in the vacuum system if you hear a hissing sound when the engine is actually running. This should be pretty noisy and easy to discern.

Issues with the fuel intake

If the fuel intake becomes damaged in any way, then the fuel that your engine needs to operate will become obstructed. To see if this is the problem, have someone push down on the gas while the car is running and look at the engine. If you notice that any of the airbox hoses collapse when the gas is pressed, that means that something is either blocking the intake, or there is a leak.
