Check Engine Light On vs. Check Engine Light Flashing
The check engine light, also known as a Malfunction Indicator Lamp, is a signal from your vehicle’s computer that there is a problem with one of the components or systems. If the light comes on you’ll want to make a point of bringing it in so that our service techs can diagnose exactly what the problem is and fix it for you, before it becomes a more serious, and more costly issue.
A flashing check engine light most often indicates that there is an engine misfire. This is a critical, and dangerous situation where unburned fuel enters the exhaust system raising the temperature of the catalytic converter causing irreparable damage. If the light is flashing you must pull over, stop the vehicle, and arrange to have it towed to our service center.
The bottom line: If the check engine light in on, you should schedule a service appointment as soon as possible. If the check engine light is flashing, your vehicle needs service NOW.
Why Your Check Engine Light is Blinking
There are many different reasons that your check engine light could be blinking, but here are just a few of the most likely culprits:
- Spark plugs
- Ignition wires
- Distributor cap
- Fuel injectors
- Pistons and rings
- Timing belt or chain
- Cylinder head
However, it could also be something as simple as a loose gas cap, which is actually a very common reason that check engine lights come on.
Have Your Check Engine Light Codes Checked
While any of the above symptoms could be the reason your check engine light is blinking, it’s tough to be sure. You can find out for sure what’s going on by having a vehicle diagnostics test run, in which a technician plugs into your vehicle’s computer to get check engine light codes that profile any potential issues with the vehicle.
How to Reset Check Engine Light
The easiest and clearest way to get your check engine light to turn off is to address the source of the problem by having your vehicle serviced. If you do, your vehicle will be more likely to last, and the technician will reset the diagnostics reader on the vehicle, so that the check engine light turns off. However, if you really want to turn it off on your own, a shortcut is to temporarily disconnect the car battery, but this will make you lose all your in-car computer data.
