Check Engine Light Diagnostics in Craig, Colorado

Advanced Testing and Repair Service

The Meaning Behind the Check Engine Light

For the past few decades, vehicles have been manufactured with the second-generation on-board diagnostics system (OBD-II). This system is responsible for monitoring the main components of your vehicle, and if it detects a problem or abnormality, it will send the respective diagnostic trouble code (DTC) to your internal computer system. You’ll be able to recognize this via the check engine light that illuminates your dashboard. If you experience a flashing check engine light, a more serious issue has been found that may require immediate assistance; we don’t recommend putting off check engine light diagnostics service in this scenario. The OBD-II system is a centralized system, which means the DTCs are universal and can be read from make to make using standard code-scanning tools. Here at Chapman’s Automotive in Craig, Colorado, we are equipped with the technology and knowledge to perform check engine light diagnostics service and the necessary repair to get your vehicle running like new again. We are open Monday through Friday, offer after-hours pick-up and drop-off, pick-up and delivery service, and welcome walk-ins! We look forward to serving you soon.

Why Is Your Check Engine Light On?

The reasons your check engine light can come on are aplenty, and the only way to figure out what exactly is going on is through professional check engine light diagnostics. We at Chapman’s believe that knowledge is power, which is why we want to share a few of the top reasons why your check engine light (CEL) may be appearing. First and foremost, it’s important to understand that the problems that trigger your CEL range in severity. Something as simple as a loose gas cap can be all it takes! If your MIL comes on shortly after fueling up, we recommend first checking to see if your gas cap is tightened. A failing oxygen sensor is another common reason, which struggles to maintain an ideal air-to-fuel mixture in your engine. If your spark plugs wear or become faulty, your CEL will likely come on. Bad spark plugs can lead to ignition problems, more fuel consumption, and damage to other components. Additional issues include a faulty mass airflow sensor, failing exhaust gas recirculation (EGR) valve, damaged catalytic converter, and a vacuum leak. If your CEL has come on, we encourage you to schedule an appointment for check engine light diagnostics service sooner rather than later to prevent further issues and damage from developing.
