Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related.
On some vehicles, (including 88-> Ford products) the 'Check Engine' light is timed to come on at around 60k miles, even if there are no problems. It's part of a maintenance scheduling system. There is often a microswitch which will allow the light to be reset, but the placement and operation of that switch varies by vehicle make and model. A technician at a smog inspection station tried to set me up for a $500 triple oxygen sensor replacement job because of that light.
A flashing check engine light is an indication of a severe engine misfire.

NO it does not. The check engine light comes on when the ECU detects a problem with the emissions system and has nothing whatsoever to do with the outside temperature.
Air gets in the fule pump and might account for the Check engine light. When you pump gas be sure to twist the cap at least three times to make sure it is tight. To make it go away, you can try adding more gas and then making the cap tight.
There are pages and pages and items that can cause a check engine light. You need to have it checked for codes with a scan tool. After repair light can be shut off with scan tool.

The check engine light is displayed in the on/run position just before starting the engine to make sure the bulb works If the check engine light flashes , that means an engine "miss" has been detected If the check engine light stays on, a possible problem with the emission control system has been detected by the powertrain control module In order to reset the light, the problem has to be corrected first. Have the vehicle scanned for trouble codes
It is possible for the check engine light to come on in a Pontiac Transport when using ethanol gasoline because it burns hotter than other gasoline. The check engine light might also come on if the oxygen sensor is bad.
yes it can
Using contaminated fuel can cause an engine misfire which will turn on the check engine light. A faulty gas cap can for sure turn on the light.
If the check engine light stays on you need to read the code(s) set in the ECM in order to begin to make repairs and make the light go away. Many of the larger chain car parts stores will check the code(s) set for nothing in hopes of selling you parts to correct the problem. It could be as simple as a loose or bad gas cap.
make sure your gas cap is on tight. sometimes this will make your check engine light come on.
The check engine light is on because the engine control module (ECM) senses a problem with the system. Resetting the check engine light without making repairs will only set the light back on again. Drive to your local auto parts store and have them read the codes that are set and with that information they can help you determine what needs to be done to cancel the check engine light. It would help to also list the year, make and model vehicle you have for us to help you.
no that shouldn't make the check engine light to come on but that's not good on the fuel pump i would change the gas in the tank
