- What causes the engine light to come on and off?
Assuming you're referring to the check engine light:
There are a number of reasons why your check engine light may be turning on and off. In some cases, it may be due to a loose gas cap or a faulty oxygen sensor. In other cases, it may be indicative of a more serious problem, such as a misfire or a problem with the catalytic converter.

- How to diagnose the cause of the engine light coming on and off
When your engine light comes on, it's telling you that something is wrong with your vehicle. But what does it mean when the light turns off again? Is the problem fixed?
Unfortunately, it's not that simple. Just because the engine light is no longer on, doesn't mean the problem has gone away. In fact, the light may only be coming on and off because the problem is intermittent.
So, how do you diagnose the cause of an engine light that comes on and off?
First, you need to understand that there are two types of engine light:
• Check Engine Light: This is the most common type of engine light. It comes on when the onboard computer detects an issue with the engine, emissions, or another system.
• Service Engine Soon Light: This light is less common, but it generally means the same thing as a check engine light.
If either of these lights comes on, it's important to have the vehicle diagnosed as soon as possible. Many auto parts stores offer free diagnostic services, so that's a good place to start.
Once you have the vehicle diagnosed, the next step is to identify the problem and fix it. This can be tricky, especially if the problem is intermittent.
If you're not sure what to do, the best course of action is to take the vehicle to a qualified mechanic. They will be able to help you troubleshoot the problem and get the repairs you need.
