If your check engine light has turned on, you don’t need to jump to the conclusion that your engine is on the verge of total disaster. Nonetheless, you should make it a priority to get to the shop for computerized diagnostics so that the underlying issue can be promptly pinpointed and resolved before it gets worse. At Gab’s Auto Repair, our local mechanics provide top-quality engine diagnostics and repair in the greater Phoenix, AZ area. Here’s a look at six common check engine light triggers. 

Failing Mass Airflow Sensor

MAF sensors monitor the amount of air coming into the engine. Indications of a MAF sensor issue include decreasing acceleration, hard starts, and rough idling.

Faulty Spark Plugs

Spark plugs help to optimize engine performance and gas mileage, so you’ll want to be sure yours are working strongly. Symptoms of a spark plug issue include difficulty starting, as well as worsening acceleration.

Problem with Battery/Charging System

Your check engine light might come on if your car has a bad battery that causes low voltage at the computer.

Bad Catalytic Converter

It’s very important that your catalytic converter is healthy. This is because it does the crucial job of turning hazardous compounds into gasses that aren’t as harmful. Symptoms of a catalytic converter problem include poor acceleration, a sulfurous odor, and darkened exhaust smoke.

Faulty Oxygen Sensor

O2 sensors keep tabs on the quantity of unburned oxygen in the exhaust system. Signs of a bad O2 sensor include worsening fuel-efficiency, increased emissions, and catalytic converter trouble.

Loose/Missing Gas Cap

If your gas cap isn’t tightly secured, then fuel could evaporate before your engine gets the opportunity to run on it. It might sound bizarre, but a loose/missing gas cap will sometimes cause the check engine light to flash on.
