Mercedes-Benz GLK 350: Check Engine Light
There are many possible causes for a check engine light to appear on a Mercedes-Benz GLK 350. Some of the most common causes include:
The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust and signaling the engine computer to adjust the air-to-fuel ratio accordingly. A faulty oxygen sensor can cause the engine to run too rich or too lean, which can trigger the check engine light.
A loose or faulty gas cap can cause the fuel system to lose pressure, which can trigger the check engine light.
- Malfunctioning Mass Airflow Sensor
The mass airflow sensor measures the amount of air entering the engine and communicates with the engine computer to determine the proper air-to-fuel ratio. A malfunctioning mass airflow sensor can cause the engine to run too rich or too lean, which can trigger the check engine light.
- Failed Catalytic Converter
The catalytic converter is responsible for converting harmful emissions into less harmful gases before they exit the exhaust system. A failed catalytic converter can cause the engine to run poorly and trigger the check engine light.
The ignition coils provide the spark that ignites the fuel in the engine's cylinders. Faulty ignition coils can cause misfires, which can trigger the check engine light.
The exhaust gas recirculation (EGR) valve is responsible for reducing emissions by recirculating a portion of the engine's exhaust back into the intake manifold. A failed EGR valve can cause the engine to run poorly and trigger the check engine light.
