It is always important to bring your vehicle in for regular maintenance. There are also some things you should inspect between maintenances as well. This will help to keep your vehicle operating efficiently and at top performance levels. One thing to always be aware of is the warning light system on the dashboard. This will alert you to any issues that might be happening to your vehicle. The check engine warning light is important because it will help prevent a much larger problem in the future, as well as time, money, and stress. Most modern vehicles have what is known as an Electric Control Module (ECM). Throughout the engine components there are several sensors placed at various points to monitor the engine’s performance. When something is not performing up to standard, the ECM indicates a problem by lighting up the Check Engine light. As summer is approaching, it is best to not to overlook nor panic when the light emerges.
Causes of the Light Turning on
While there are several causes that result in the check engine light showing up on your dashboard, there are a few components you should always check, as they can possibly be the main cause to your problem. Your oxygen sensors can be the one to blame if your check engine light comes on. An oxygen sensor is placed between the engine and the catalytic converter and its job is to make sure that the exhaust of the engine performs efficient combustion. Also, something as simple as overfilling the gas tank can trigger the light to come on. The mass airflow sensor can also be to blame. If the filter becomes clogged or is installed improperly it can cause a malfunction. Lastly, your spark plugs can begin to fail over time and that too can be a cause of why your check engine light is coming on.
Inspect the Source of the Issue
When something triggers the check engine light, the ECM will store that information until it is retrieved by a qualified mechanic, which is typically provided free of charge from most mechanics. In severe cases of a check engine light, the light will either turn red or begin to flash if the problem in the engine is serious. If you notice either of those two signs, it is advisable to pull the vehicle over and consider having it towed. Continuing to drive your vehicle in such condition is bad for your vehicle and can potentially make the problem worse.
Ways to Fix the Problem
Before you take your vehicle to the mechanic, there are some things you can do yourself to see if you can fix the problem. First you can try tightening your gas cap. One of the easiest causes of a check engine light is a loose gas cap. A loose gas cap can trigger several emission related codes to your vehicle’s diagnostic system. After you have done some investigating, bring your vehicle to our service shop and have them diagnose the problem.
