Dealing With A Check Engine Light
Some people dread the check engine light. Others continue to drive without any care in the world with their check engine light illuminated. The reality of the light is that it can mean anything from an extreme engine problem to a minor issue that you can solve as a DIY. Mostly, it all depends on whether the light is steady or blinking.
Below is an overview of blinking and steady check engine lights.
Steady Light
A steady light usually points to a minor or moderate problem. Such problems usually don't mean that your engine is in imminent danger of failure. However, you still need to diagnose and fix the issue.
Ideally, you should find a safe place to pull over and look at the possible causes of the steady light. Here are some of the common problems:
- Loose gas cap
- Fouled spark plug
- Malfunctioning aftermarket alarm (this can drain the battery)
- Dead battery
If you can't spot the problem right away, schedule an appointment with your mechanic for a professional diagnosis. Note that it might take some time for the check engine light to disappear after you apply the fix. Therefore, drive for a short while after trying the usual solutions, such as tightening the gas cap.
Blinking Light
A blinking light typically points to a serious engine problem. Blinking light means your engine might suffer extensive damage if you don't solve the problem. Ideally, you need to get a mechanic to diagnose and fix the issue as soon as possible.
Below are some of the serious engine problems that can trigger the blinking light:
- Malfunctioning catalytic converter
- Engine misfire
- Failed sensors (such as mass airflow sensor)
- Overheated engine
- Damaged fuel injector
If the blinking light comes on while you are driving, the first thing is to reduce the engine load. Reducing engine load includes things like:
- Reducing your speed
- Reducing your luggage
- Unhitching trailers
- Accelerating gently if necessary
All these are necessary so as not to strain the engine since the malfunction causing the blinking light has already affected the engine's efficiency. Forcing the engine to perform as usual might trigger immediate damage. If you have a diagnostic tool, you can plug it in and read the code to diagnose the problem and asses its urgency.
Hopefully, you won't be dealing with a serious engine issue any time soon. If your engine does malfunction, consult an auto repair shop for a diagnosis and solution before the problem worsens.
