The ‘check engine’ light and the Oxygen Sensor
In every car, there is a small amber lamp that can be found in the dashboard. It is a tiny bulb that is behind a plastic pane about the size of a 1×1 ID picture. On it, an important message is inscribed. Normally, the words “check engine” can be found on it. As for other vehicles, is says “service engine soon.” These phrases, however telling they are, does not have in them the sense of urgency that will make the owners of these autos to have their engines checked as soon as possible. When this light flashes, it is important for vehicle owners to actually make time to have their engines inspected.
The check engine light, also known as the malfunction indication light (MIL for short), lights up when there were detected problems with the engine ranging from the most simple to somewhat complicated ones. Most often than not, the MIL comes on if the gas cap is not screwed tight enough. Also a common problem is when the oil dipstick is not pushed all the way. These are minor problems that may occur in one’s engine. Other than these, the check engine light could also signify semi-minor problems like a faulty oxygen sensor. Having a faulty oxygen sensor leads to poor fuel economy and poor exhaust emissions. The engine is one of the most vital components of one’s vehicle. In order to enjoy a good ride, one must take care of the engine and address the MIL when it lights up.
