Tip & How-To about Ford Explorer

Check Engine Light When the check engine light comes on and won't go off, it is a sign that your vehicle's computer has detected some problem with the emission system. Determining the exact cause of the emission failure can only be done with a diagnostic scan. However, just because the light is on doesn't necessarily mean there is a big problem , because the light can be triggered by any one of a number of minor problems. At many autozones or O'Riley's they will take a special code reader and tell you what is wrong with your car for free.

Check Engine or
Malfunction indicator light (MIL)
The Check Engine or Service Engine Soon light or an icon resembling the engine is called, in technical terms, the Malfunction Indicator Light or MIL. The MIL light comes on when your vehicle's computer detects a fault that can affect your vehicle's fuel economy and emissions. There is no button to reset the Check Engine light, but if the fault that caused it doesn't happen again, the light will turn off by itself. If the MIL light stays on, have the problem checked out, because in some cases, the problem could get worse if not repaired in time. Think of the Check Engine light as an early warning sign. To check why your MIL light came on, your dealer or mechanic will have to diagnose your car with a special scan tool.

Why would my check engine light be on


The check engine light comes on when your vehicles on board computer detects an emissions related fault. if the light is flashing you are doing serious damage to your engine during operation if the light stays on steady then there is a problem with your vehicle causing it to pollute more. possible causes range from evap lines and purge valves to catalytic converters. best place to start would be to take the vehicle to a service facility to have the stored trouble code read.

well i have a car model toyota corolla x 2004 auto transmition.i have a problem that some times engine check light illuminate itself and keep on till i turn the engine switched off,some time it will not come at all but most of the time it illuminates it self i dont know what does it means and whats going wrong with the engine kindly help me for this thnks


Hi

When the check engine light comes on and then goes off after a while, means that the computer in yur car is detecting a problem that is not present all the time, this is called a -soft code- once the computer doesn't detect the problem, resets itself and the code is erased from memory and the check engine light goes of.

While the light is on, take the vehicle to an Autozone store, they will get the computer trouble codes and give you a print out of the problem. Like I said, It is important that you take the vehicle while the light is on, otherwise they may not detect the trouble.

Good luck
