First, if your vehicle’s 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 highway speeds, tow or haul heavy loads. Take it easy driving and bring it in to be checked out.
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 to get it checked out.
Some more information about how the Check Engine Light works… 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 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 checked out at Douglas Automotive Repair. Our 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 him a starting place as he diagnoses the cause of the problem.
