Ranging from mild to severe, there is a problem with the engine that is indicated through seeing the check-engine light illuminating on the dashboard can arise many emotions to the surface. Many will get a little anxious, especially when you are driving to the next destination when the light pops on. The light coming on can become overwhelming if there are any accompanying smells or sounds unusually manifesting. Our experts can run a diagnostic to find the underlying issue at Top Notch Body Shop & Mechanic. The most common reasons as to why the check-engine light has turned on are shared below.
Evaporative Emission Control System
The Evaporative Emission Control system (or EVAP) is in place, which monitors the gasoline vapors from not exiting the gas time and fuel system or releasing into the air. Broken valves, faulty gas caps, or leaking vacuum hoses and vents can affect the EVAP from these simple issues arising. The vehicle will need to be serviced if it causes the check-engine light to illuminate, however.
Spark Plugs & Wires
Setting in motion the check-engine light is from the spark plugs and wires not effectively functioning will contribute to electrical problems. They are an essential element to the vehicle’s electrical system and permanent damage to a vehicle’s catalytic converter can be the result since spark plugs are often ignored. Engine misses or pings are produced, rough engine idling, power losses and surges, and other such erratic engine performance are a few red flags of this is rough engine idling. It is best to get the problem resolved as quickly as possible to prevent expensive repairs if the check-engine light comes on.
Mass Air Flow Sensor
The mass airflow sensor being affected can cause the check-engine light, indicating an issue. Because when the mass airflow sensor is not working properly the engine’s performance significantly drops due to the unmanaged airflow, the fuel efficiency being reduced is a classic symptom.
Ignition Coil
To check-engine light becoming lit, the ignition coil issues are another likely source. The ignition coils ignite the spark plugs with the use of an electric current from the car’s battery. Should there be any impedance with the ignition coil, the electric current running through the car is disrupted. Because the entire electrical system can be negatively impacted, if this is the cause and you need professional care.
Oxygen Sensor
To operate at maximum performance, the oxygen emissions levels need to be managed so that the vehicle’s engine. The oxygen sensors gauge the gasses that leave the engine to ensure that the correct ratio of oxygen and fuel are being pumped through the engine. Leading to the engine light to pop on when the ratio is imperfect, the fuel economy of the vehicle drops.
