If the check engine light comes on while you’re driving, don’t panic! Pay attention and see if the car is driving any differently than normal. You may be wondering, “Can you drive a car with the engine light on?” Whether or not it’s safe to keep driving with the check engine light on depends on vehicle performance and the root cause of its illumination. Just be sure to have your car inspected as soon as possible after the light turns on. Don’t neglect needed engine repair! If nothing seems out of the ordinary, you can continue driving the car. The cause could be anything from a faulty oxygen sensor to a bad MAF sensor. It could also mean your catalytic converter has failed and quit working. The check engine light is tied into your car’s onboard diagnostics system, and it’s designed to light up (usually in yellow) whenever something goes wrong with any of the components and sensors. Problems in the electronic control system are stored in a “trouble code” to identify the source of the issue. With the use of a diagnostic computer, your mechanic can pinpoint the problem and take care of any necessary adjustments or repairs. Wondering can you drive a car with the engine light on?

Here are three steps to help you determine whether it’s safe to continue driving or if you need to stop immediately:
- What else is wrong? - In addition to the check engine light, your dashboard may also indicate low oil pressure or overheating issues. If these lights come on, pull over and shut off the engine as soon as you can. Some cars may have a red check engine light to alert you to stop right away, while a yellow light stands for investigation.
- Take it easy! - If performance problems accompany the check engine light, lower your speed and take it easy on the engine. Avoid speed surges and erratic shifting. If you’re towing a trailer or carrying heavy equipment, try to unload as soon as you can to prevent a potentially costly engine repair.
- Tighten the cap! - If the light comes on after refueling, check that the gas cap is tight. The sensor is detecting a leak in the evaporative emissions system. It may take several restarts of the engine to reset the light.
