Why is my Check Engine Light on?

Posted on April 13,16 by cccadmin

The Check Engine Light strikes fear into the hearts of some in Glenwood Springs and is totally ignored by just as many. Just what it means is a mystery to most Glenwood Springs drivers.

Let’s get the urgency issues out of the way first. If your family car’s check engine light is flashing , that means that something is wrong that could cause severe engine damage. Naturally, Glenwood Springs drivers should get that taken care of right away at Jim’s Automotive Service.

If your check engine light is flashing, you shouldn’t drive at Glenwood Springs highways speeds, tow or haul heavy loads. Take it easy all the way to your Glenwood Springs service center.

If the light is glowing steadily, auto owners should keep an eye on it for a day or two. If the light doesn’t go off, schedule an appointment with Jim’s Automotive Service to get it checked out.

An explanation on how the Check Engine Light works may be informative. Most of your family car engine functions are controlled by a computer, not surprisingly, called an engine control computer. The computer is able to adjust many engine parameters for environmental conditions, engine condition and even the way you drive in Glenwood Springs.

In order to make these adjustments, the computer relies in a network of sensors to provide data. The computer knows the proper operating range for each sensor. When the sensor reading is out of range the computer runs some tests and may turn one the Check Engine Light.

A simple example is a loose or missing gas cap. This may cause one of the sensors to read out of range. The family car’s computer doesn’t know of it’s a serious condition that caused the reading or just a loose gas cap, so it stores a trouble code and turns on the Check Engine Light.

Now when you tighten up the gas cap the sensor readings will be in the correct range. The computer will keep checking on the report for a day or two. Since a bad reading didn’t come up again, it turns off the Check Engine Light. The computer will also try and make adjustments to compensate for some readings. If it can do so, it’ll then turn off the Check Engine Light. If the problem can’t be resolved then the light will remain on and you should get your family car looked into at Jim’s Automotive Service.

Your Jim’s Automotive Service technician will plug a scanner into the on-board diagnostic port and read the trouble code stored in the computer. The trouble code will give Jim’s Automotive technician a starting place as he diagnosisthe cuase of the problem.
