If your check engine light comes on, it can be alarming. Is something about to go wrong? If your light is on, it usually means your car’s emissions control system is faulty and the vehicle is polluting the air beyond allowable federal standards. Let’s take a look at what engine diagnostics will tell you is going on and what to do about it in Des Moines.
The Gas Cap is Missing or Damaged–Or Was Put on Incorrectly
Sometimes, engine diagnostics identifies the cause as a missing or damaged gas cap. This is a relatively minor issue, and one that’s easily addressed. Continuing to drive without a gas cap is bad for the environment and your mileage.
A Spark Plug Malfunction
Another possible cause is a malfunctioning or broken spark plug. If you’re experiencing problems starting your car or truck, this is a likely culprit. It’s important to seek assistance right away; leaving a spark plug issue unattended is likely to cause further damage to your vehicle.
Faulty, Loose, or Dirty Mass Air Flow Sensor
Another potential reason for your “check engine” light to activate is a faulty mass air flow (MAF) sensor. This sensor determines the ratio of fuel-to-oxygen while your engine is running. In some cases, the sensor may just be loose or dirty, but your auto repair specialist will need to perform engine diagnostics to be sure.
