What is triggering my check engine light? Visit our Phoenix auto shop for diagnostics!An illuminated check engine light doesn't automatically indicate that your engine is on the cusp of failure. Nonetheless, it'll be best to visit the shop for computerized diagnostics so that the problem can be identified and remedied before it escalates and becomes more costly to repair. At Greg Clark Automotive Specialists, our local mechanics use advanced diagnostic equipment to make sure that problem is properly identified. Then we can complete flawless repairs.

Common Reasons the Check Engine Light Turns On

Oftentimes, check engine lights get triggered by problems with certain sensors. A faulty MAF sensor may cause the light to illuminate. Signs of a bad MAF sensor include hesitation during acceleration, as well as stalling shortly after starting the engine. A faulty O2 sensor can also cause the light to come on, and may cause misfiring or rough idling.

Oftentimes, a failing catalytic converter is to blame for an illuminated check engine light. Signs of catalytic converter trouble include worsening acceleration, decreasing fuel-efficiency, and a sulphurous stench. It's important that your catalytic converter is working properly so that your car is minimally polluting.

There are some cases in which a faulty battery is what triggers the check engine light. This can occur when a bad battery causes low voltage at the computer.

Another potential trigger is failing spark plugs. Signs of bad spark plugs include misfiring and rough idling. Bad ignition coils can also cause the light to turn on, and may cause poor acceleration.

If you're lucky, all that's causing your check engine light to come on is a loose gas cap. When a gas cap is loose or missing, fuel may evaporate before it gets directed toward your engine, so you'll want to make sure it's tightly fastened after each time you fill up.
