How Long to Drive Car After Resetting Check Engine Light
The check engine light is a warning light that illuminates on your car’s dashboard when the engine control module (ECM) detects a problem with the engine or emissions control system.
When the check engine light is on, it means that the ECM has stored a trouble code in its memory.
The trouble code indicates the specific problem that has been detected.
You can reset the check engine light by disconnecting the negative battery terminal for 30 seconds.
However, this will only clear the trouble code from the ECM’s memory.
It will not fix the underlying problem that caused the check engine light to come on in the first place.
If you reset the check engine light without fixing the underlying problem, it will likely come back on again.
Therefore, it is important to have the problem diagnosed and repaired as soon as possible.
How Long Can You Drive With the Check Engine Light On?
How long you can drive with the check engine light on depends on the severity of the problem that caused it to come on.
If the problem is minor, such as a loose gas cap, you may be able to drive for a short period of time without causing any damage to your car.
However, if the problem is more serious, such as a misfire or a faulty oxygen sensor, you should not drive your car at all until the problem has been repaired.
If you are unsure about the severity of the problem, it is best to err on the side of caution and have your car diagnosed by a mechanic as soon as possible.
What to Do if the Check Engine Light Comes Back On
If the check engine light comes back on after you have reset it, it means that the underlying problem has not been fixed.
You should have your car diagnosed by a mechanic as soon as possible to determine the cause of the problem and have it repaired.
Conclusion
Resetting the check engine light will not fix the underlying problem that caused it to come on.
It is important to have the problem diagnosed and repaired as soon as possible to avoid causing damage to your car.
