Oh No! My “Check Engine” Light is On!

Troy Check Engine Light Repair | Trojan Auto Care

When your vehicle's "Check Engine" light is illuminated, it is because your vehicle's computer system has identified a problem. Today's vehicles are equipped with something known as an Electronic Control Module (or ECM) that controls the operation of the engine. The ECM is also responsible for performing a check of your vehicle's engine to make sure it is running at maximum efficiency and with the lowest possible emissions. There are a number of factors that can affect engine performance and emissions including speed, load, engine temperature, and the quality of gasoline, to name a few.

Although it may seem daunting if lit, the “Check Engine” light often detects small problems before they have become major repair problems. It will alert you to problems like reduced engine performance, poor fuel mileage or excessive exhaust emissions. That's why it is extremely important to have your vehicle checked when the check engine light is on. Sometimes it could be something as simple as a gas cap that wasn't tightened properly or has a leak.

What should I do if the “Check Engine” Light is On?

The easiest way to take care of this problem is to bring your vehicle to Trojan Auto Care in Troy, OH.

Why did the light come back on a week after I had it repaired?

Your vehicle's onboard diagnostic (OBD) system is continually performing a series of “self-tests.” When a problem is detected, the system will try to compensate and many of these tests are temporarily turned off. If the light comes back on, it usually means there were multiple problems. Once repairs are completed, the OBD system re-starts its series of self-tests. This is why it is important to bring your vehicle to experts like Trojan Auto Care.
