Check Engine Light On in Murfreesboro? When to Keep Driving and When to Call a Tow

A check engine light can mean anything from a loose gas cap to a problem that could damage the engine. Here is a simple way to decide what to do when it comes on while you are driving around Murfreesboro.

Steady light vs. flashing light

A steady light usually means the car has logged a fault that should be checked soon, but it is often safe to drive carefully to a shop. A flashing light usually signals a serious misfire. Driving on it can overheat and ruin the catalytic converter, so pull over when it is safe and limit driving.

Quick checks you can do safely

• Make sure the gas cap is tight. A loose cap is a common cause, and the light may take a few drives to clear.
• Look at the other gauges. High temperature, low oil pressure, or a battery warning alongside the check engine light means stop driving.
• Notice how the car feels. Shaking, loss of power, smoke, or a burning smell are reasons to pull over.

Get the code read

Many auto parts stores will read the trouble code for free, and an inexpensive OBD-II scanner lets you read it yourself. The code points a mechanic toward the problem but is not a full diagnosis.

When a tow is the safer choice

• The light is flashing and the engine runs rough.
• The temperature gauge is in the red or you see steam.
• Oil pressure or charging warnings are on too.
• The car stalls, will not restart, or loses power on the road.

Towing in these cases is usually cheaper than paying for engine damage caused by driving a few more miles.
