An indication there is a problem with the engine, ranging from mild to severe, when you see the check-engine light illuminating on the dashboard can arise many emotions to the surface. Many drivers get anxious, especially when you are driving to the next destination once the light pops on. The light coming on can become overwhelming if there are any accompanying smells or sounds unusually manifesting. Our experts at Top Notch Body Shop & Mechanic can run a diagnostic to find the underlying problems. There are common reasons as to why the check-engine light has turned on that we at Top Notch Body Shop & Mechanic would like to elaborate on them today.
Evaporative Emission Control System Leak
The Evaporative Emission Control system (or EVAP) is in place in order to monitor the gasoline vapors from not exiting the gas time and fuel system or releasing into the air. Faulty gas caps, leaking vacuum hoses and vents, or broken valves, among other simple problems can occur that affects the EVAP. You should have the serviced if the engine light comes on for this reason.
Oxygen Sensor Fail
In order for the vehicle’s engine to operate at maximum performance, the oxygen emissions levels need to be managed. The oxygen sensors gauge the gasses that leave the engine ensures that the correct ratio of oxygen and fuel are being pumped through the engine. When the ratio is imperfect, the fuel economy of the vehicle drops, which leads to the engine light to pop.
Spark Plugs and Wires Replacement
To set in motion the check-engine light, the spark plugs and wires not effectively functioning will contribute to electrical problems. Should the spark plugs be ignored, as they are a vital component to the vehicle’s electrical system and permanent damage to a vehicle’s catalytic converter is commonly the result. Erratic engine performance like rough engine idling, engine misses or pings are produced, power losses and surges are a few of the red flags. It is best to get the problem resolved as quickly as possible to prevent expensive repairs if the check-engine light comes on.
Ignition Coil Problems
Another likely source to the check-engine light becoming lit is the ignition coil problems. 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. Since the entire electrical system can be negatively impacted if this is the cause and you need professional care.
Bad Mass Airflow Sensor
An indication that something is affecting the mass airflow sensor stems from the check-engine light. 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.
