Especially when you are driving to the next destination, many will get a little anxious when the light pops on. he 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 Highway 30 Garage. The most common reasons as to why the check-engine light has turned on is what we would like to list today.
Can Spark Plugs Cause Your Check Engine Light to Come On?
Contributing to electrical problems that will set in motion the check-engine light is ineffective spark plugs and wires. Spark plugs are an essential element to the vehicle’s electrical system, though they are frequently ignored, and permanent damage to a vehicle’s catalytic converter can be the result. Engine misses or pings are produced, rough engine idling, power losses and surges, and other such erratic engine performance are common 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 Can Make Check Engine Light On
Another likely source to check-engine light becoming lit are ignition coil issues. 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. Because the entire electrical system can be negatively impacted, this this is the cause, and you need professional care.
Will a Bad Oxygen Sensor Cause the Check Engine Light to Come On?
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 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 is when the fuel economy of the vehicle drops.
What Symptoms Will a Bad Mass Air Flow Sensor Cause?
Something is affecting the mass airflow sensor when the check-engine light comes on. To measure the correct amount of air is entering to an engine is the design of the mass airflow sensor. 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.
Can an EVAP Leak Cause Engine Problems?
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. Broken valves, faulty gas caps, or leaking vacuum hoses and vents are simple issues can arise and affect the EVAP. The vehicle will need to be serviced, however, if it causes the check-engine light to illuminate.
