What to Check When the Check Engine Light is On

Your check engine light is a valuable part of your diagnostic system, which is the hidden system in your vehicle that alerts you when something may be wrong. All in all, your diagnostic system is a lifesaver, but the check engine light can be a source of headaches when the problem isn’t so obvious. Instead of searching for a needle in a haystack, check these vehicle components to see if your check engine light goes off. However, if you ignore your check engine light, you could be placing your life and the lives of others in danger. Additionally, the cost of your car insurance could increase significantly if you are responsible for a wreck due to the performance of your vehicle.

Replace Your Fuel Cap

Seemingly unimportant, your fuel cap is an integral component of your vehicle. It works in connection with your emission system, which keeps your engine purring like a cat. If your fuel cap is faulty, then it could trigger your check engine light. Additionally, in other vehicles, it could cause a systemic response from your vehicle that places your vehicle in a safety mode in which it can’t accelerate. If your check engine light is illuminated, start by checking your fuel cap, and replace it if necessary.

Check Your Oxygen Sensors

Another common problem that can trigger your check engine light is your oxygen sensors, also known as your O2 sensors. Your O2 sensors are a component of your exhaust system that keeps your engine running. Typically, when your O2 sensors are not working properly, you’ll smell a distinctive odor coming from your vehicle. At any rate, after replacing your fuel cap, let a professional connect your vehicle to their diagnostic tool to determine whether you need new sensors if your light remains on. Many local auto part stores offer this service for free or a nominal fee.

Check Your Spark Plugs

Spark plugs give your engine life, so to speak. The spark created by the plugs in your vehicle is responsible for starting your vehicle’s engine. Vehicles have a number of spark plugs, and if there is a problem with even one plug, it could trigger your check engine light. Additionally, you will notice a difference in your vehicle’s performance. For instance, your vehicle may seem to skip gears, and it may start to use more fuel than normal. If you notice any of these changes, you should take your vehicle to your local dealer or mechanic as soon as possible. In most cases, you should change your spark plugs every 100,000 miles to be on the safe side.

Maintaining your vehicle is one of the fundamental aspects of being a safe driver. Problems with your vehicle can trigger accidents that lead to an increase in your car insurance. You can avoid potential auto insurance increases while extending the life of your vehicle by getting it checked regularly, not simply when your check engine light comes on.
