Overview of the Onboard Diagnostics System

Your check engine light (CEL) is a key player in your onboard diagnostics system (OBD-II). The OBD-II system is a computer-based system built into modern vehicles to monitor and diagnose the performance of various components, such as the engine, transmission, and emissions. It continuously collects data from the sensors throughout the vehicle. If it detects a problem, it will generate the diagnostic trouble code (DTC) and trigger the check engine light warning. The DTC is stored in the vehicle’s computer and is only retrievable through check engine light diagnostics. The OBD-II system is an essential part of vehicles that helps make them more reliable, efficient, and safer. If your CEL has come on, it’s time to schedule an appointment at McNeil’s Auto Care in Sandy, Utah. We possess advanced code-scanning tools to troubleshoot the exact problem.

Problems Behind the Check Engine Light

The check engine light, also known as a malfunction indicator lamp (MIL), is a warning signal that indicates the OBD-II system has identified a problem. Numerous issues can trigger the CEL, ranging from minor to severe and potentially dangerous problems. One of the most common is faulty oxygen sensors, affecting fuel efficiency and emissions. A loose or damaged gas cap can also cause the check engine light to come on. Other issues include a bad mass airflow sensor, malfunctioning catalytic converter, worn ignition coils, worn spark plugs, and defective exhaust gas recirculation (EGR) valve. It’s essential to address any problems that cause the MIL to come on promptly through check engine light diagnostics. Ignoring the warning could lead to more severe and costly issues. A flashing CEL indicates a critical problem that demands immediate attention. For your safety, we advise you to pull over and contact us for guidance on the necessary steps to take; it may be unsafe to continue driving the vehicle. We can arrange for our towing service to pick up your vehicle if needed.
