What the Check Engine Light Means
One common issue that car owners dread is the “check engine” light coming on. Our ASE-Certified technicians at Dave’s Ultimate Automotive in Cedar Park, Texas, are experienced and ready to assist you with check engine light diagnostics. The check engine light, also known as the malfunction indicator lamp, alerts you of possible issues with your vehicle’s engine, transmission, or emissions system. All vehicles manufactured for the United States since 1996 and beyond are equipped with a computer system called OBD-II (on-board diagnostics). It monitors the health of these systems and informs you when something could be wrong. When this occurs, it stores the respective diagnostic trouble code in the computer (to be retrieved later during check engine light diagnostics service). It illuminates the engine light in your dashboard. A range of problems can be causing the light to come on, and it takes a professional to troubleshoot it properly.
Possible Reasons for the Engine Light to Come on
When the check engine light turns on, it could mean a wide range of things. Something as simple as a loose gas cap that has a broken seal; the gas cap is responsible for keeping fuel vapors in and preventing moisture from invading the system. Worn or defective spark plugs are a common cause, which can delay the process of combustion and even create a situation where misfiring happens. Misfiring can lead to severe and irreversible engine damage if not taken care of. Similarly, the check engine light will trigger if the ignition coils fail to function properly. Ignition coils create the high voltage needed to produce the spark at the spark plug. Other complications include a faulty catalytic converter, a bad mass airflow sensor, a vacuum leak, and an exhaust recirculation valve failure.
Any problem detected with the air/fuel delivery process, modules, sensors, and wiring warrant the need for professional assistance. Whether a major or minor problem, when the light turns on, one thing’s for sure – you know that it’s time to schedule a check engine light diagnostics service.
