Corcoran Drivers Ask: Why is My Check Engine Light On?

Dec 24th, 2018

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

First, if your 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 all the way to your Corcoran service center.

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 friendly and knowledgeable service advisor at Pro-Tech Auto Repair Inc to get it checked out.

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 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 computer will also try to make adjustments to compensate for some readings. If it can’t 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 at Pro-Tech Auto Repair in Corcoran.

These lights serve a necessary function and that is to warn the driver of things that are possibly unsafe or that could lead to a costly repair if left unattended. A popular misconception that I often hear when speaking about the check engine light with customers is that, if they have had the code read and cleared and the light comes back on, they know what it is and that it is unimportant. Nothing could be further from the truth. The problem that they were experiencing that day may not have impacted the way the car ran but that was that day at that time. There is only one light and over 200 things that can turn it on, some of which can and will due severe damage to the engine or emission system if not addressed.

Your friendly and knowledgeable professionals at Pro-Tech Auto Repair will plug a scanner into the on-board diagnostic port and read the trouble code stored in the computer. The trouble code will give them a starting place as they diagnose the cause of the problem.
