Part two of a series on the check engine light explores some more meanings of this enigmatic system display.

The Check Engine Light and Your Car’s Emission System

Like it or hate it, emissions testing is part of life in the Phoenix area. By Arizona law, you can’t even egister your car unless you pass emissions. And during emission testing, the check engine light is an instant fail, and you’re out $35 for the inspection fee plus any repairs. One major source of problems where the check engine light is concerned is your car’s catalytic converter. As auto parts go, this part is essentially worthless. All it really does is allow your car to pass emissions.

What causes a catalytic converter to fail? Well, usually when they go it is a result of other scheduled maintenance not being done, such as replacing oxygen sensors and spark plugs. In fact, you do regular scheduled auto maintenance, your catalytic converter can conceivably last for the life of the car. But how does the check engine light work where your car or truck’s emissions system is concerned?


As we said above, if your check engine light is on, the minute the emissions inspector sees it, you fail the emissions test. As to why such a harsh stance, a good percentage of problems that trigger the check engine light are emission system related. You want to pass emissions obviously because the alternative is a lot more dangerous. Without passing emissions, you can’t register your vehicle, which means that you won’t be able to drive your car legally and are essentially a target for any police or DPS to pull you over and give you what can be an expensive fine.

If you do regular auto maintenance, however, if you’re lucky, you may never see the check engine light. If you have any questions about the check engine light, be sure to call the right personnel and remember to stay calm. Focus on the solution and not the problem. And the solution is really quite simple. Call your auto repair shop in Mesa.
