Understanding the Check Engine Light
Nobody wants to see the check engine light come on, but it’s a possibility for anyone who owns a vehicle. Oftentimes, it seems, a lot of drivers aren’t quite sure what it means. Since a well-informed driver is a safer driver, let’s decipher what your check engine light is telling you. Despite its name, it isn’t for a single component such as the engine; it’s a warning that something is wrong in your powertrain… somewhere. It could very well be the engine, but it could also be the transmission, the exhaust system, or even the fuel system. The engine light is a part of your on-board diagnostics system (OBD-II), which is what monitors the various systems in your vehicle. If it detects a problem or abnormality with the operation of one of the components, it sends a diagnostic trouble code to the system and is stored there. From there, our team at Wally’s Auto Care in Ammon, Idaho will be able to take the necessary steps for repair.
