What Does The Check Engine Light Mean?

Some of us may not be aware of it but most modern cars these days have an on board monitoring system that is fed by a variety of sensors throughout the entire car from ambient air temperature to the amount of oxygen in a car’s exhaust system. But what does it mean if glanced down at the dashboard to see that the check engine lights turned on?

Malfunction indication light, is designed to keep the driver informed of any number of sensor failures or engine irregularities.

Adjustments to ensure that the engine is running as efficiently, and cleanly as possible, but when one of those sensors fail, or gets a strange reading, you get the check engine light.

Sometimes, there may be a simple solution and can be checked by yourself. For example, failing to tighten your gas cap all the way, not fully re-inserting your engine oil dipstick or a loose oil fill cap can cause the check engine light to flash. If you’ve check all of the above and you still have the little light on your dash, visit your mechanic for advise.

More serious problem and not addressing the issue will inevitably lead to an engine failure.
