Why Would a Car’s Check Engine Light Turn On?
Did you know that in the first week after the check engine light comes on, 36.1% of people take their car to the technician?
Automobiles, at one point or another, will have malfunctions that can occur when driving. This includes having issues with your check engine light. Once this light turns on, it can become a source of frustration and anxiety, but there’s no need to panic.
The check engine light has been designed to give us early signs of engine trouble. Even though having the light turn on may be inconvenient to some, it can end up saving you more money and time in the long run.
If you’re wondering why the check engine light came on in your vehicle, continue reading. The below list covers various causes of the light turning on and what you can do to fix your car.
Dirty Fuel Injectors
Fuel injectors are responsible for spraying fuel into the vehicle’s engine. When the injectors become clogged or covered in a layer of dirt and grime, they are unable to deliver fuel. This throws off the fuel-air ratio within the engine.
It leads to poor combustion, reduced engine performance, and decreased fuel efficiency. Dirt and grime can block the injectors, resulting in a misfire or an increased amount of fuel being delivered.
Faulty Ignition Coils
Ignition coils are located on the cylinder walls. When they malfunction due to age, mileage, or a defect, they can result in the vehicle failing to generate the spark necessary to ignite the fuel and air mixture. This can cause problems such as reduced engine performance, misfiring, starting difficulty, or increased fuel consumption.
It is advised to have the car inspected and repaired by a qualified mechanic as soon as possible when the check engine light comes on. It is also important to learn more about ignition coil.
Low Coolant Level
Without the correct coolant level, the engine can overheat and cause serious damage to the engine. The temperature of an engine rises due to running the engine.
When there is not enough coolant, the engine temperature will increase beyond its ideal temperature. When this happens, the computer sends a signal to the check engine light, warning you that there is a potential issue.
If your check engine light is on, one of the first things that you should check is the coolant level to make sure it is at its ideal level. If it is not, then you should have the system examined and repaired.
Oxygen Sensor Issue
An oxygen sensor is located in the exhaust system and monitors the amount of oxygen in the exhaust fumes. If a problem occurs, the oxygen sensor will not be able to check the oxygen levels printed in the exhaust gases, resulting in the check engine light turning on. Possible common oxygen sensor issues can include poor connection, malfunctioning car engines, or wear and tear.
If the wiring becomes brittle due to heat, it can wear away and result in a bad connection. Aging parts can also corrode, resulting in a bad connection.
Don’t Ignore the Check Engine Light
The check engine light is a crucial indicator of car maintenance needs. Taking prompt action when this light illuminates can save you hundreds of dollars in repairs and help your car maintain its optimal performance. If your check engine light illuminates, be sure to get your car checked and serviced as soon as possible.
