So what happens if you drive with your check engine light on?
Nothing really will happen while driving when the check engine light comes on. It all depends on the reason the light is on in the first place and whether the light is solid or its flashing.
The solid light just tells you that the ECU has faced something outside normal operating parameters in the car engine.
How long can you drive with check engine light on?
So you are driving and suddenly the check engine light appeared and then you start wondering how long can you drive with check engine light on?
The answer to this question will depend on whether the light is solid or not.
If the car’s check engine light is solid, you will be able to drive the car for 160kilometres without any problem, but after then you might start experiencing issues.
This also depends on the type of code that is stored in the car’s computer. If it is a faulty engine sensor, the car typically will use made up sensor values to keep running for a while.
There will be a decline in fuel productivity and car performance, but you will be able to drive without trouble. It’s not an emergency, but you should still try to see your mechanic as soon as possible
