One of the worst experiences you can have as a motorist is to look at your car's dashboard and see the check engine light flashing. Before you start to fret over a potentially costly repair, it is worth noting that many reasons for the light turning on are relatively simple and inexpensive repairs. Here are some possible causes you can investigate before going to the mechanic. 

The Gas Cap

Your gas cap has a bigger job than just protecting your gas from possible thieves. The cap is responsible for helping to maintain pressure in your fuel tank. If the pressure drops, your car will mistakenly believe there is a problem with the fuel lines or the engine and trigger the check engine light. It also helps to prevent your gas from evaporating quickly, which could lead to the need to fuel up often.

The simple fix for this is to check your gas cap and ensure that it is securely in place. You should also check the condition of the cap. If the cap is damaged, you can find a replacement at an auto parts store. 

The Battery

Your battery is the heart of your car's electronic control system. There are several problems with the battery that can lead to the check engine light being triggered. 

One such issue involves the battery's cables. Check the cables for wear or corrosion. If the cables are worn, they will need to be replaced. You also need to ensure that the cables have been properly tightened. The cables needs to be securely installed in order for the battery to remain adequately charged. 

If you have recently replaced your car's battery and the check engine light came on after that, ensure that the rating of the battery meets the car manufacturer's minimum cranking amperage. You can locate this information in your owner's manual. You can also find the correct rating by looking at the specifications on your car's old battery. Replace the battery with a new one if the rating is incorrect.

In the event that your car's check engine light is still on, schedule an appointment with your mechanic. Not only can he or she diagnose the issue, but the mechanic can also repair your vehicle. Putting off an assessment, after troubleshooting at home, could result in the condition worsening over time and lead to a bigger auto repair bill.
