What is causing my check engine light to turn on?


When your check engine light comes on, it doesn't automatically mean that your engine is about to fail. Nonetheless, it's best to get to the shop for computerized diagnostics so that any developing issues can be pinpointed and resolved before they get worse and end up costing more to repair. At The Organic Mechanic, our local auto shop can expertly diagnose your car's engine trouble and then get right to work on addressing it.

Common Check Engine Light Triggers

One common reason the check engine light turns on is a failing catalytic converter. Your catalytic converter is essential to reducing the amount of polluting emissions created by your vehicle. When it isn't working properly, you may notice issues like worsening acceleration, decreasing gas mileage, and a sulphurous odor. A problem with an oxygen sensor can cause the check engine light to illuminate, and can also cause catalytic converter trouble. Another sensor that sometimes triggers the check engine light is the mass airflow sensor. Signs of a bad mass airflow sensor include poor acceleration, as well as stalling out shortly after you fire up your engine.

When a malfunctioning battery causes low voltage at the computer, it can trigger the check engine light. It's also possible for bad spark plugs to set off the light. Vehicles made in the past twenty years can commonly go 100,000 miles before needing new spark plugs, while older cars tend to need plug replacement more frequently. Failing ignition coils are another reason the check engine light could get triggered. Indications of a bad ignition coil include: engine stalls, worsening fuel-efficiency, and no-start. A more bizarre reason the check engine light will sometimes come on is that your gas cap is loose or missing.
