When the check engine light illuminates, a sense of dread and uncertainty enter your thoughts. The light flips on with varying issues that can be scaled from minor to major. With so many other frustrating circumstances being encountered on the road, such as abnormal sounds coming from the engine, getting lost, or even a challenging blind spot can contribute to feeling overwhelmed. When it is confirmed with the check engine light on, it can be a real problem. You can get a little peace of mind and how to prevent any damage if you can learn why the engine light may be brightening your dashboard. With that in mind, we at Citywide Towing Service would like to share the most common reasons for a check engine light.
Ignition Coil Check Engine Light
Ignition coil problems can be the source to the check engine light. By using the electric current from the car’s battery, ignition coils ignite the spark plugs. The electric current running through the car is disrupted should there be an impedance with the ignition coil. The entire electrical system of the vehicle can be negatively impacted and requires immediate action from a trusted professional.
Spark Plugs & Wires Can Make Check Engine Light Go On
The spark plugs and wires not effectively performing can result in the electrical issues that sets off the check-engine light. Ignoring problems with spark plugs and wires can potentially result in permanent damage to a car’s catalytic converter, as they are an essential element to the vehicle’s electrical system. It will cause rough engine idling, engine misses or pings, and erratic engine performance like power losses and surges. Get the vehicle checked as soon as possible as early detection can prevent expensive repairs.
Bad Oxygen Sensor
There needs to be a managed level of oxygen emissions in order for a vehicle’s engine to operate at maximum efficiency. To ensure that the correct ratio of oxygen and fuel are being pumped through the engine, the oxygen sensors gauge the gasses that leave the engine. The fuel economy of the vehicle drops when the when the ratio is imperfect. The engine light will come on for this reason.
Mass Air Flow Sensor Problems
The mass air flow sensor experiencing issues can prompt the check-engine light to switch on. Calculating how much fuel should be added to the mix and that the air that enters an engine is measured correctly is the job of the mass airflow sensor. The engine’s performance significantly drops, and the fuel efficiency can be greatly reduced when the mass air flow sensor is not working properly.
Evaporative Emission Control System Leak
To make certain the gasoline vapor does not exit the gas time and fuel system as well as releasing into the air, the Evaporative Emission Control system (or EVAP) is in place to monitor it. Broken valves or leaking vacuum hoses and vents, as well as faulty gas caps can be the cause. The check engine light will come on to notify you that you need to bring your car in for service, whatever the problem may be.
