Check Engine Light

Check Engine Light Photo 1Most vehicles on the road have at least one computer that monitors and controls the overall operation. Any time a malfunction is detected, the check engine light comes on. This light is an indication that there is a problem. In some cases, this light may flash on and off, indicating the problem may have been temporary. Other times, the light comes on and remains on. This is an indication that the vehicle needs to be inspected by a qualified Minnesota check engine light service.

Even if the light flashes on and then off, this could be an indication that a problem is starting. If you see this, it is still important to have Accurate Auto inspect the vehicle to catch a problem before it becomes a more expensive issue.

How The Light Works

The vehicle’s computer monitors a large quantity of sensor readings that measure the overall operation of the vehicle. If the computer sees a problem, it will turn the check engine light on in order to warn the driver that the vehicle needs serviced.

When the sensor reading is not normal, it records a trouble code. If the problem is severe, the light will switch on automatically. If the problem is temporary, the computer will still record the code, but it will wait for the issue to occur again. If the problem occurs again, the check engine light switches on and stays on until a Maple Grove check engine light professional checks the vehicle and resets the light by clearing the code.

Some individuals feel that the trouble code that the vehicle’s computer stores tells the auto repair technician the exact issue, but it is not that easy. The trouble code tells the mechanic what sensor is giving off an abnormal reading. Unfortunately, it can’t tell the technician why it is giving an abnormal reading. The code just gives the technician a place to start.

Common Trouble Codes

There are some rather common trouble codes. One is the gas cap being loose. If your check engine light comes on, check your gas cap. If that fixes it, then you know that was the problem. Another common issue is the air throttle control going bad. If you notice your vehicle is not idling properly, that valve could be going bad. A faulty spark plug or two is another reason, as well as a clogged fuel injector, a faulty O2 sensor, and a dirty exhaust gas recirculation valve. These are all issues that need to be addressed as soon as possible.
