When your check engine light comes on, your car’s computer is letting you know something is wrong in the engine. But knowing which part of the engine is affected and the severity of the problem is anyone’s guess. The check engine light can be a frustrating warning for these reasons. Due to this uncertainty, many people tend to ignore it.
A study done by CarMD.com found that “car owners are ignoring small problems that significantly reduce gas mileage, but also result in more expensive, catastrophic repairs” and that “64% of U.S. adults who ever owned/leased a vehicle admitted to having put off automotive maintenance/repair at one time or another.”
Here are a few of the most common problems that could cause your check engine light to come on:
- Gas cap is loose.
- Oxygen sensor needs to be replaced.
- Catalytic converter needs to be replaced.
- Mass air flow sensor needs to be replaced.
- Spark plugs and wires need replacing.
