An illuminated check engine light doesn’t necessarily mean that disaster is imminent. But you should still promptly get to the shop for diagnostics. This way, the issue can be pinpointed and addressed before it escalates. At All Engines & Transmissions, we provide expert check engine light repair in the greater Westminster, CO area. Here’s a look at five common reasons the check engine light comes on.
Oxygen Sensor Malfunction
Oxygen sensors measure the amount of oxygen in the exhaust gasses, helping to regulate fuel injection and ensure optimal engine performance. When an oxygen sensor malfunctions, it can result in decreased fuel-efficiency and increased emissions.
Faulty Mass Airflow Sensor
The mass airflow sensor (MAF) monitors the amount of air entering the engine, allowing the engine control unit to adjust the fuel injection accordingly. If the MAF sensor malfunctions, it can lead to issues such as rough idling, poor acceleration, and increased fuel consumption.
Catalytic Converter Issues
The catalytic converter plays a crucial role in reducing harmful emissions by converting toxic gasses into less harmful substances. However, it can become clogged or damaged, leading to decreased engine efficiency and increased emissions.
Spark Plug or Ignition Coil Problems
Spark plugs and ignition coils are essential components of your vehicle's ignition system, responsible for igniting the air-fuel mixture. Worn or faulty spark plugs, as well as failing ignition coils, can lead to misfires, rough idling, and reduced engine performance.
Loose or Faulty Gas Cap
Although it may seem bizarre, something as simple as a loose or faulty gas cap can trigger the check engine light. A missing or damaged gas cap can allow fuel to evaporate before it is directed to your engine for use.
