A Vacuum Leak Can Impede Your Engine’s Performance

You rely on your car, truck, or utility vehicle’s engine to perform reliably and safely every time you drive your automobile. Aero Auto Repair advises that if one of the vacuum hoses starts to leak inside of the engine, it will fill the engine with air. This will create problems with the engine’s performance. We will discuss these problems and other signs of a vacuum leak below.

Check Engine Warning

The excess air flowing into the engine will cause many of the system sensors to send error codes to your vehicle’s main computer chip, the engine control unit (ECU). Normally, the ECU will just adjust the fuel in the combustion chamber to balance out the excess air. It’s unable to do this, however, with a vacuum leak because the air continually flows into the engine. Because it cannot correct the issue itself, it will turn on the check engine light to warn you of engine trouble.

Component Malfunction

The reason why the engine vacuum is routed through the hoses is so that it can power components inside your engine. This includes things such as your power steering pump. If the engine has a vacuum leak, you may notice problems with your vehicle’s power steering because the pump isn’t being powered properly. This is just one example of a component malfunctioning because of the vacuum leak.

Hissing or Suction Sounds

Engine vacuum leaks make noise. Specifically, a small leak will create a hissing sound coming from the vacuum hose. If the vacuum leak is large, the vacuum hose will sound just like your household vacuum hose. In other words, you will be able to hear suction coming from your engine.

Performance Trouble

As we discussed above, the excess air that fills the engine will create performance problems. Specifically, your vehicle will hesitate when you try to accelerate, whether from a stop or to pick up speed. You will also have a sputtering engine when you are driving at higher speeds and when the engine is under stress.

Sporadic or High RPMs

Finally, there is a visual indication that your engine has a vacuum leak. If you suspect you have this type of leak, check to see if your tachometer needle is moving up and down in spurts. If it is, the RPMs in your engine are increasing every time they are met with a burst of air.
