Why is my Check Engine Light Is On?

Is your Check Engine Light on? Have you ever wondered why it may come on then go off again, or maybe its on and wont go off at all? Do you wonder why it matters that it’s on anyway? Well here is a brief explanation of the purpose of the check engine light. It comes on when your vehicle’s computer detects a fault that can affect your vehicle’s fuel economy and the exhaust emissions. If your check engine light is on your car will not pass a Smog Test. In many states they require your vehicle to pass an emissions test to be eligible for registration. California State requires this test to be completed when registering your vehicle or within a period of time deemed by the DMV. A temporary registration will be issued which is usually good for 90 days. For information on this issues also check out 5 common check engine light problems.
