What Does The Engine Warning Light Mean?

If you have seen the engine warning light turn on in your dash, this is something you shouldn’t just ignore. This light is very important and can signify a variety of different issues, which I will list below.

One thing it may indicate is your oxygen sensor needing to be replaced. If you don’t replace it, your engine will burn more fuel than is necessary, you will lose fuel economy and get fewer miles per gallon, and the faulty sensors can damage your spark plugs and catalytic converter.

A second thing it may indicate is a damaged, loose, or missing gas cap. If you fail to replace this part, you can lose fuel through evaporation and may end up taking a lot more trips to the gas pump!

Another thing that an engine warning light may be telling you is that you have a bad catalytic converter. If you don’t replace your catalytic converter, your car will not pass an emissions test, you will have reduced performance and fuel economy, and your vehicle may run at a higher temperature.

The engine warning light may also indicate bad spark plugs or plug wires that need to be replaced. You will experience bad performance (engine missing, reduced power) and reduced fuel economy if you don’t get new spark plugs or plug wires. Worn out plug wires and plugs can also clog the catalytic convertor or damage the ignition coils and oxygen sensors.

One final thing that may be indicated is that it is time to switch out the Mass Airflow Sensor (MAF). Failing to do so can cause damage to the spark plugs, catalytic converter, or the oxygen sensors. You may also experience reduced performance and fuel economy with a worn-out MAF.

The thing is, you want to make sure that your speedometer is working correctly in the first place so that it can detect issues such as those mentioned above. If the speedometer is not working properly, some of the lights might not even turn on when an issue arises, or the gauges may only work intermittently. For that reason, you should regularly check your instrument cluster and note any problems. If you see that any faults really are present, you should look into getting speedometer repair immediately.
