Keep Your Car Healthy

Many cars are built with an Onboard Diagnostics System (OBD). The computer system in your vehicle monitors the performance and regulates various things like the engine speed (RPM), the ignition timing, and fuel mixture. In some cases, it even controls the automatic transmission and tells it when to shift. With so much technology packed under a single hood, various things can go wrong especially if you have not checked out Luckily, there is a built-in warning system within the vehicle to warn you before things get out of control. The ‘check engine’ light is a yellow indicator that comes on when the scanner detects a problem. All you need is a diagnostic tool in place to tell you what is wrong.

Why Does The ‘Check Engine’ Light Come On?

Whenever the OBD system detects a problem, it signals the driver by turning on the ‘Check Engine’ yellow light on the dashboard. The system also stores a related trouble code in its memory. These codes can help diagnose the problem and find a probable solution. The ‘Check Engine’ light can come on due to various reasons. It can be trivial problems like a loose cap or a loose wire, or it could be something complicated like a misfiring engine or even a malfunctioning sensor. Only a diagnostic computer or maybe a scan tool can detect such problems.

There are many reasons for the Engine light being illuminated. The job of an oxygen sensor is to keep the ratio of fuel to air consistent. Excess fuel or oxygen in the engine prompts the sensor to equalize the issue using the car’s computer. However, these oxygen sensors fail occasionally mainly because you haven’t serviced the car or because you have used fuel that contains too much ethanol. Ignoring this problem will affect the mileage of the car and cost you a lot of money on fuel.
