Until you have had the car looked at, the check engine light will remain lit.
What is the most common reason for check engine light?
The most common reason for a check engine light to be illuminated is a loose or faulty gas cap. This can happen due to daily wear-and-tear or a faulty seal in the cap, which will cause the fuel tank to lose pressure, leading to the light being illuminated.
Other common causes of a check engine light include a failed oxygen sensor, a malfunctioning catalytic converter, an issue with the mass airflow sensor, an issue with the spark plugs or wires, or an issue with the exhaust system.
If the check engine light is illuminated, it is important to take it to a mechanic to get it checked out, as a malfunctioning engine can lead to decreased fuel efficiency and other problems.
Why would check engine light come on and then go off?
The “check engine light” is a signal that something is wrong with the vehicle’s engine systems. It’s triggered by certain components that signal the car’s computer with a code to indicate a problem. The code is read and the light is illuminated, indicating to the driver that there is an issue that needs to be addressed.
When the check engine light comes on, it is necessary to diagnose the issue and address it. If the issue is resolved, the light may turn off, indicating that the issue is no longer present. Depending on the type of issue, periodic inspections may be mandated to ensure that the problem is still resolved.
Sometimes however, the light may come on and then go off without the driver intervening. This can happen when a loose gas cap or partially faulty sensor sends a false signal to the computer. If the emission level threshold is not crossed, the code is not stored and the light will reset on its own.
In this case, a periodic inspection by a professional automotive technician may be recommended to identify and resolve any potential problem. It is important to read the vehicle’s computer for exact code details before attempting to diagnose the issue.
Is it OK to drive with check engine light?
