What is the most common reason for check engine light?
Replacing a faulty oxygen sensor — a sensor used to optimize a vehicle’s fuel-to-air mixture to increase gas mileage and reduce emissions — is the most common cause for a check engine light.
Should I be worried if my check engine light is on?
Both a solid and flashing engine check light indicates that a problem has been detected. However, a flashing engine check light indicates that it is a serious problem that requires your immediate attention. If you see a flashing light, it’s best to contact a mechanic as soon as possible to prevent serious damage.
Is it OK to drive with check engine light on?
The rule of thumb is that if the check engine light is flashing, you can’t keep driving the car. It’s an emergency. Often it indicates an engine misfire. If you keep driving, you will likely cause irreversible damage, mostly to the (expensive) catalytic converter.
What does a solid check engine light mean?
A solid Check Engine Light can mean something like a loose gas cap, or it can indicate a more in-depth problem like a fuel, timing, or transmission issue. Get your car diagnosed, although the urgency isn’t the same as if the light was flashing at you.
What could be wrong when check engine light is on?
The light could be a minor issue, such as a faulty gas cap, or it could mean something more serious, such as a misfiring engine. If the light begins flashing, however, it indicates a more serious problem, such as a misfire that can quickly overheat the catalytic converter.
How many miles can you drive with check engine light on?
When the check engine light is solid, you can typically drive the car for hundreds of miles without an issue. Of course, that depends on which code is stored in the vehicle’s computer. If an engine sensor is faulty, the car will usually use made up sensor values to keep running.
Can low oil cause the check engine light to come on?
Low oil pressure: If your car is low on oil, it can cause your check engine light to go off. This is often shown in its own glowing light along with the check engine light on the dashboard.
What should I do if my check engine light comes on?
