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

First, if your vehicle Check Engine light is flashing, that means that something is wrong that could cause severe damage to the catalytic converter or other components. Get that taken care of right away. If your Check Engine light is flashing, you shouldn't drive at Urbandale highway speeds, tow or haul heavy loads. Take it easy all the way to Ultimate Automotive Service in Urbandale.

If the light is glowing steadily, you should keep an eye on it for a day or two. If the light doesn't go off, schedule an appointment with your Urbandale service advisor to get it checked out.

Some more information from Ultimate Automotive Service on how the Check Engine light works may be informative. Most of your vehicle 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 Urbandale.

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

The vehicle computer will also try to 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 vehicle looked at at Ultimate Automotive Service. Your friendly and knowledgeable 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 your Ultimate Automotive Service technician a starting place as he diagnoses the cause of the problem.
