Causes of a Car Engine Unexpectedly Turning Off
If the problem lies with your engine or other vehicle components, there will be a number of things that should be looked at. A service technician will want to look at the electrical, airflow and fuel system, in addition to anything else that is deemed necessary.
- Exhaust Gas Recirculation
- Idle speed sensor
- Mass airflow sensor
- Fuel injectors
- Fuel filter
- Fuel pump
- Air filter
- Throttle position sensor
You’ll want to ensure that all these parts are in proper working order and that none of them are clogged up. If all of these parts seem fine, you may need to do some additional investigation or have things looked at by an expert. Before doing so, it may also not be a bad idea to check out your battery as well.
Does Your Vehicle Have Stop-Start Technology?
Though there are many reasons to be concerned about an engine that suddenly shuts off while driving, there are instances where this is actually supposed to happen. That’s the case with any vehicle equipped with stop-start technology. You may even find some of these vehicles here at American Automotive Group.
These systems are actually designed to shut down the engine when at idle, such as when waiting at a stop light. As soon as you start to accelerate, the engine will nearly instantaneously start up again. In fact, you won’t even notice it after a while. The reason for this type of technology is to save fuel… having the engine running less means you don’t waste gas while sitting still.
We hope you find out the reason why your car engine is shutting off, but for anyone interested in learning more about stop-start technology and whether any vehicles have it here are American Automotive Group, be sure to contact us.
