Modern vehicles are designed to communicate with their owners when there is a problem. One of the main methods that vehicles use for this communication is the check engine light. When this indicator becomes illuminated, it means that the vehicle needs service of some kind. The vehicle’s computer has sensed a problem that it can’t correct, so it turns on the warning light, which may be an image of an engine or text that reads “check engine” or “service engine soon.”
When the computer turns on this light, it also stores a code in its memory that identifies the specific issue. A technician can read this code using a diagnostic tool. Following are some of the most common reasons for check engine lights in Conway, AR to be illuminated:
- Loose gas gap: One of the first things to check if your “service engine soon” light comes on is your gas cap. If this has not been closed, or it is not fully sealed, the car’s computer will sense an issue. A loose or cracked gas cap allows vapors to leak out, which affects the entire fuel system as emissions go up and gas mileage goes down. Try tightening the gas cap, or you may need to have it replaced.
- Failed oxygen sensor: An oxygen sensor monitors your fuel consumption and ensures the right balance of oxygen and exhaust. If this sensor fails, the computer can no longer obtain the data regarding emissions. This makes your car unsafe and also lowers your gas mileage. Most vehicles today have between two and four sensors, which must be replaced on occasion due to debris buildup.
- Malfunctioning catalytic converter: This component converts carbon monoxide into materials that can be safely emitted. Without it, a vehicle’s exhaust releases harmful gases. If it malfunctions, the vehicle also achieves poor gas mileage and speed. If it fails, the car won’t run.
- Worn spark plugs: Spark plugs can last between 30,000 and 100,000 miles, but will wear out eventually and must be replaced. These parts assist with the initiation of combustion that starts your vehicle’s engine. They are essential to the smooth operation of a vehicle, so be sure to replace them right away when they fail.
- Poor mass airflow sensor: This part tells the computer how much fuel to add to the engine, based on airflow. This filter typically needs to be replaced once each year. If it is not working properly, the car will get poor gas mileage, emissions will increase and the vehicle may stall. Before this happens, the vehicle should indicate an issue by turning on the check engine light in Conway, AR.
