After changing your oil, you may notice that your check engine light is still on. This can be frustrating, but it’s important to remember that the light is not always an indication of a serious problem. In many cases, it can be reset simply by following a few simple steps.
One of the most common reasons for a check engine light to come on after an oil change is because the oil filter was not tightened properly. This can cause oil to leak out, which can trigger the light. To fix this, simply tighten the oil filter until it is snug. You may also need to replace the oil filter gasket if it is damaged.
