The name Acura is derived from a Latin word “acu” which means accuracy. Reliability combined with this accuracy is what the brand is known for today. To provide accuracy of their engines, engineers designed the dashboard of each model to include a check engine light to alert you to potential problems with your car that will negatively affect the engine.
The check engine light is controlled by the OnBoard Diagnostic (OBD) system of the vehicle. Whenever there is an issue with the engine or other connecting components, the OBD detects it and the check engine light will turn on. The check engine light informs you of any issues with your engine immediately, thereby allowing you to pull over and have it towed or bring it to our repair shop. This safeguards the engine block and protects you, your passengers, and your vehicle.
Potential Issue That May Cause The Check Engine Light To Come On
The following are some common reasons why the check engine light of your Acura comes on. It is important to pay attention to your Acura, and never ignore the check engine light whenever it is illuminated.
- Malfunctioning Oxygen Sensor: If the oxygen sensor of your Acura is malfunctioning, it can cause the check engine light to come on. A malfunctioning oxygen sensor can improperly indicate that the catalytic converter of your Acura is under excess pressure. This case can be corrected by a professional mechanic that specializes in repairing Acura vehicles.
- Problem with Spark Plugs: Spark plugs help to ignite the fuel in the engine. If there is a problem with the spark plug, the car will misfire. This causes the check engine light to come on since it negatively impacts the engine. When this is the case, you need to replace or service the spark plugs.
- Faulty MAF Sensor: The Mass AirFlow (MAF) sensor supplies the correct amount of air required by the engine. If there is an issue with the MAF, the air/fuel mixture becomes lean and this would lead to misfires of the engine. The type of misfire that occurs is called lean misfire. When the MAF is faulty, the check engine light would be illuminated and you need to take your Acura for a check-up.
- Failed Catalytic Converter: This is the most serious cause of the check engine light being illuminated in your Acura. The catalytic converter system converts the toxic emissions produced by fuel combustion into environmentally-safe gases. If the catalytic converter of your Acura is faulty, your car would pose a danger to everyone around it and to the environment as well. Although it is very expensive to repair, it is important to have this repaired properly.
- Loose Gas Cap: A loose-fitting gas cap may cause the check engine light of your Acura to come on. When you forget to tightly close the gas cap of your vehicle, the fuel vapor may leak and the onboard diagnostic system might read this as an issue with the engine thereby turning on the check engine light. So if you see the engine light illuminate, check the gas cap first to see if it’s a quick and easy fix.
