Dashboard Warning Lights to Take Seriously

Dashboard Warning Lights to Take Seriously

The engine control unit is the main computer chip in your car, truck, or utility vehicle. This chip keeps an eye on the system’s sensors to make sure everything is working properly. A sensor will report an error to the engine control unit if something goes wrong. To alert you of the problem, the unit will turn on a dashboard warning light, such as the check engine light. Let’s go over the components and systems that cause the engine control unit to engage the check engine light.

Catalytic Converter

Assume, for the sake of argument, that your catalytic converter is clogged. Because the catalytic converter does not have its own light, the engine control unit will receive the error code and engage the check engine light.

EVAP Control System

The EVAP control system is no exception. If something goes wrong with it, you’ll get a check engine light. The EVAP control system is responsible for preventing gasoline or diesel fuel from evaporating from the engine.

Engine Control Unit

Surprisingly, if the engine control unit fails, the check engine light will turn on. Your engine may also die and refuse to restart, in addition to the dashboard warning. Unfortunately, the engine control unit will need to be replaced.

Gas Cap

The gas cap is another thing that keeps your fuel from evaporating. This cap forms a seal over the gas tank, ensuring that no fuel vapor escapes into the environment. If the cap is old, it may no longer be able to form a seal.

Mass Airflow Sensor

Oxygen Sensor

The oxygen sensor serves a unique purpose. It measures how much oxygen is in the vehicle’s exhaust rather than checking the air inflow. Check engine warnings are frequently caused by the O2 sensor. The O2 sensor has a 100,000-mile lifespan.

Spark Plugs

Finally, if the spark plugs are misfiring, the engine control unit is likely to turn on the check engine light. Wear and tear, as well as a problem with the engine control unit, can both cause the spark plugs to misfire.

Always seek the advice of a qualified auto mechanic at a local repair shop who has previously dealt with similar problems.
