Car Shut Off While Driving Check Engine Light On

Causes

There are a number of potential causes for a car to shut off while driving, with the check engine light on. Some of the most common causes include:

Fuel system problems: A fuel pump failure, clogged fuel filter, or other fuel system problem can prevent the engine from getting the fuel it needs to run.
Ignition system problems: A faulty ignition coil, spark plugs, or other ignition system component can prevent the engine from sparking and starting.
Electrical system problems: A loose or damaged electrical connection, a bad battery, or a faulty alternator can all prevent the engine from getting the power it needs to run.
Engine mechanical problems: A seized engine, a broken timing belt, or other engine mechanical problem can cause the engine to shut off while driving.

Symptoms

In addition to the check engine light coming on, there are a number of other symptoms that may indicate that a car is about to shut off while driving. These symptoms include:

Engine sputtering or hesitating: If the engine is not getting enough fuel or spark, it may start to sputter or hesitate.
Loss of power: If the engine is not getting enough power, it may start to lose power and eventually shut off.
Strange noises: If the engine is making strange noises, such as knocking or rattling, it may be a sign of a serious problem that could cause the engine to shut off.

What to Do

If your car shuts off while driving, the first thing you should do is pull over to a safe location. Once you are safely parked, you should turn off the engine and check the check engine light. If the check engine light is on, it means that there is a problem with the engine that needs to be diagnosed and repaired.

You can try to restart the engine after it has shut off. However, if the engine does not restart, you will need to call a tow truck to have the car towed to a mechanic.

Regular maintenance: Regular maintenance, such as oil changes and tune-ups, can help to keep your car running smoothly and prevent problems from developing.
