May go out after filling and driving. Give it a few days before getting it looked at. Below are some insights.
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 tests the computer runs the car through a drive cycle, 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. OR hook up a scanner that is capable of clearing codes, and hope that none are still active. Disconnecting the battery can create other headaches and will not likely solve your dilemma. Best bet is to contact the local snap-on dealer and have him refer you to a known good shop that specializes in this technology-he will know.
The "check engine light" is a warning light that is illuminated, usually when there is a problem with the emission system, but may also occur if the computer detects a misfiring cylinder, knocking, or other symptom of your engine running outside of its normal operation.
It is a good thing once you understand it.
A check engine light is often simply the result of a loose gas cap, which triggers error code P0452.
But understand that many scenarios are possible with the "check engine light" The vehicle's powertrain computer (note that some vehicles have 17 different computers) will run a series of self-tests. They will only run under certain criteria. And they can be vastly different from manufacturer to manufacturer. Some self-tests are not run until preceding ones have run successfully. So if there is a problem in one particular area that is preventing another self test from running, you can have a situation where one problem is fixed, but another still exists. If you fix a problem and drive the car through a drive cycle that sets the monitor (or self test) the light will go off as it passes that criteria that triggered it in the first place.
After 1996, the auto industry went to a idea called OBD II (on board diagnostics). This was to get all the manufacturers onto a similar plane for troubleshooting and powertrain control. While they still differ vastly, many corrections and adaptations were made for technicians to better fix the check engine light problems. Prior to this there were so many different and poor troubleshooting data from a check engine light problem that resolving the problem was much more difficult. Many early warning light of this nature were set to illuminate based on mileage. An Oxygen sensor was one of the things that were meant to be replaced when that mileage was hit. This is much like many current "Change oil lights� that are set based on a pre-set mileage.
In this specific case, where the check engine light and the low fuel light come on at nearly the same time, it is possible that the check engine light came on because the engine ran lean for a second or two, caused by low fuel pump pressure, which in turn was caused by low fuel level in the tank. If the engine is running normally and smoothly, fill the tank and give it a few days use to see if the light goes off before seeking further help. If the engine is not running well, lacks power, or otherwise seems abnormal, further troubleshooting is required immediately.
Many auto parts supply stores will read the OBD-II code from your car at no charge.
Was it the "Check Engine" light or the "Check Gauge" light that came on? I know some of the later fords had a check gauge light that would come on if you left your fuel filler cap off or loose, or if you were low on fuel.

A check engine light in any vehicle is a warning that there is an issue with the motor. In a specific vehicle, as in a Ford Contour, it is best to check the manual or with a mechanic to identify the issue.
The check engine light comes on when the computer detects a problem and sets a code. You need to have it diagnosed with a scan tool.
Check the lower end of the engine- follow the + battery cable
Check for fuel and spark.
No, but it has a temperature gauge that you need to check regularly.
You have a flat battery! Check that your batter terminals are connected
Easy, fix the problem that caused the light to come on in the first place.
Every sensor on the engine and transmission can cause the light to come on.
i HAVE A 98 AND THE BELT BROKE TWICE AND DID NO DAMAGE TO THE ENGINE. The first time I was on freeway doing 75 and it broke. I have a '97 Contour and had no damage to the engine when my timing belt broke. Make sure you check your pulleys to ensure that the bearings are good. Mine were not and had to replace them.
The check engine light can come on for a variety of reasons. You will have to have the vehicle connected to a code reader to determine the specific reason for the light to be on.
30 SECONDS WHITOUT BATTERY
To reset the check engine light on a Hummer H3, the problem causing the check engine light should be repaired. If this does not fix the problem, the battery may need to be disconnected and re-connected.
Trouble code P0117 means:Engine coolant temperature circuit low input
Which engine? If this is a check engine light or emissions test failure be certain ex. gas & intake passages are clear. Bob
Turn on the ignition and look at the instruments. You will see the Check Engine Light come on for a few seconds and then go off. If you see the light it is working.
Well if it takes you more than 30 seconds to check it, check the engine stopped. If just after the engine run.
Easiest way is to disconnect the negative battery cable for a couple minutes then reconnect. This will clear the error codes from the computer. If everything is okay, the CHECK ENGINE light will stay off.
The check engine light, on your Hyundai Elantra can be reset by removing the fuse. Keep the fuse out for 10 seconds and replace it to its slot.
unplug the battery for 30 seconds.
Disconnect the battery for 30 seconds
When you turn the ignition key to the run position just before starting the vehicle the check engine light will light for a few seconds to check the bulb
For the 1994, you have to remove the negative battery cable, then depress the brake and hold it in for 5 seconds to reset the check engine light.
check harmonic balancer. check harmonic balancer.
Get the Engine Checked Don't waste your money getting your engine checked. Just disconnect your negative side of your battery for 10 seconds. Reconnect it and your done, no more check engine light.
