If your check engine light comes on, it’s best to promptly visit the shop for diagnostics. This way, the issue can be identified and addressed before it gets the chance to escalate and potentially leave you stranded. At Powerhouse Auto Repair, we provide expert check engine light diagnostics and repair in the greater Tallahassee area. Here’s a look at five common reasons the check engine light turns on.

Oxygen Sensor Failure

Oxygen sensors measure the amount of unburned oxygen in the exhaust system. This data is sent to the car’s computer to adjust the air-fuel mixture. A malfunctioning oxygen sensor can lead to a drop in fuel-efficiency, increase emissions, and cause problems with the catalytic converter.

Catalytic Converter Issues

The catalytic converter helps convert harmful gasses produced during combustion into less harmful substances before they are released into the atmosphere. A failing catalytic converter can result in reduced engine performance, increased emissions, and poor fuel-economy. 

Mass Airflow Sensor Problems

The mass airflow (MAF) sensor measures the amount of air entering the engine to ensure the proper air-fuel mixture. A faulty MAF sensor can lead to engine performance issues such as stalling or trouble starting the car. It can also cause a decrease in fuel-efficiency. 

Loose/Faulty Gas Cap

A loose, damaged, or missing gas cap may trigger the check engine light. The gas cap seals the fuel system. If the cap is faulty, fuel may evaporate before your engine can run on it.

Faulty Spark Plugs or Ignition Coils

Spark plugs ignite the air-fuel mixture. Ignition coils generate the electricity needed by the spark plugs. If either component is faulty, it can cause the engine to misfire, leading to a check engine light. Signs of bad spark plugs include misfires and rough idling.
