This is another dashboard warning light that is often misunderstood. What does it indicate, and what should you do if it occurs?
The check engine light on the dashboard may be quite concerning for most drivers who are not mechanically savvy.
The good news is that its illumination does not always signify that your engine is about to collapse and plunge you into financial hardship.
However, it is crucial to have your car inspected as soon as possible.
Depending on the issue, the check engine light may flash or remain illuminated.
If the light remains illuminated, the problem isn’t significant, and you should be able to continue driving as long as no other warning lights illuminate. If the engine feels like it’s running smoothly and the water temperature is okay, then there is no immediate danger, just ensure that you get it looked at as soon as possible.
Because the car suspects improper fuel combustion, the check engine light will frequently appear. A defective oxygen sensor that detects unburned oxygen in the exhaust of the vehicle, spark plug difficulties, or even poor fuel cap tightening could all be to blame.
When the light is flashing, it usually indicated the presence of something more dangerous, such as the release of unburned fuel into the exhaust system, which could damage the catalytic converter. If the light flashes, drive carefully home, shut off the engine, and have it looked at as soon as possible.
The first tool a mechanic will use to identify why the check engine light is on is an ODB2 diagnostic scanner, which connects to a port under the dashboard of any car made after 1996. This gives mechanics information about a number of aspects of the car’s performance, including issues, each with it’s own code.
The code immediately resolves the issue without the need for extensive troubleshooting. When the problem is resolved, the scanners will turn the check engine light off.
