Many will get a little anxious, especially when you are driving to the next destination as 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. We would like to discuss the most common reasons as to why the check-engine light has turned on today.
Bad Spark Plugs Can Cause Check Engine Light to Come On
Setting in motion the check-engine light, the spark plugs and wires not effectively functioning will contribute to electrical problems. Permanent damage to a vehicle’s catalytic converter can be the result when the spark plugs are ignored as they are an essential element to the vehicle’s electrical system. Engine misses or pings are produced, power losses and surges, rough engine idling, and other such erratic engine performance are a few red flags. It is best to get the problem resolved as quickly as possible to prevent expensive repairs should the check-engine light comes on.
Failing Ignition Coil
To check-engine light becoming lit, 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. In the event 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 Causes Check Engine Light
The vehicle’s engine to operate at maximum performance, oxygen emissions levels need to be managed. 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. When the ratio is imperfect, the fuel economy of the vehicle drops, leading to the engine light to pop on. It can be vehicle’s battery as it is other common reasons that check-engine light comes.
Bad Mass Airflow Sensor
Some that is affecting the mass airflow sensor is to check-engine light can be an indication that something. To measure the correct amount of air is entering to an engine, the mass airflow sensor is designed. 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.
Evaporative Emission Control System Leak
The Evaporative Emission Control system (or EVAP) is in place to monitor the gasoline vapors from not exiting the gas time and fuel system or releasing into the air. Like broken valves, faulty gas caps, or leaking vacuum hoses and vents, it is a simple issue can arise that affects the EVAP. The vehicle will need to be serviced, if it causes the check-engine light to illuminate, however.
