What to Do if Your BMW Check Engine Light Comes On A faulty MAF sensor can cause your engine to misfire, ultimately causing poor fuel economy, performance, and potentially more unnecessary damage to your engine. Like the oxygen sensors, the MAF sensor measures the amount of air entering the engine and help ensure the proper air-fuel mixture.

Faulty Mass Air Flow Sensor: When exposed to dirty or particle-rich air, the Mass Air Flow (MAF) sensor could fail.

An engine with too little fuel is at risk of total engine failure, and an engine with too much fuel will create excessive smoke and odor. A faulty oxygen sensor can cause your vehicle's computer to supply the engine with too much or too little fuel. The oxygen sensor provides vital air-fuel mixture information to the ECU.

Faulty Oxygen Sensor: Due to long exposure to hot exhaust gas, your oxygen sensor might need replacing.

Faulty spark plugs or spark plug wires can cause your engine to misfire, reducing fuel economy, performance, and even prevent it from running altogether. Your spark plugs create a hot spark that ignites the air-and-fuel mixture in the cylinder, allowing your engine to start and run.

Fouled Spark Plugs or Spark Plug Wires: Over time you will eventually need new spark plugs or spark plug wires.

A failing or clogged catalytic converter can severely impact fuel economy and vehicle performance.

The catalytic converter is a vital part of the emissions system, removing toxic carbon monoxide. Failing Catalytic Converter: Your catalytic converter can eventually clog with material, especially with higher mileage vehicles.

Gas cap issues can reduce fuel pressure and allow fuel vapors to escape, reducing fuel economy and increasing harmful emissions. Loose Gas Cap: Your gas cap is loose, broken, or simply missing.Below we have highlighted the most common causes of a check engine light.
