Check Engine Light

The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

If the problem has been fixed and the light remains on you need to disconnect the battery and then reconnect it. That should reset the check engine light.

It can.

If the check engine light is flashing that means an engine cylinder misfire has

been detected . You can drive it in for repair , just avoid any rapid acceleration

or deceleration because you can damage the catalytic converter

the check engine light comes on when the computer sees one one of the many perimeters (sensors, voltage, etc) go out of range. Witch could be anything from low coolant to injector voltage low. Internationals have a 3 digit on board flash code. Once you have retrieved it phone your local dealer and they can tell you what it means.

Probably not. They check your dash lights for your turn signals.

Really depends on model year, and what specifically the light is. If it's the stop engine light, then a fault has been detected which will cause the engine to shut down. On older trucks with mechanical engines, a stop light typically meant that inadequate air pressure is in the system.

You can try disconnecting the negative battery cable for 5 minutes and if that does not work you will need to use an OBD2 scanner to reset it. Know that if you do not repair the problem that caused the light to come on then it will just come back on after you reset it.

You will need an OBD2 scanner to retrieve the code that has been set.

Go to AutoZone. They do it for free.

You replaced the cap and it will take quite a few driving cycles for the light to go off if that was the culprit. Try disconnecting the negative battery cable for 5 minutes and that might reset the light.

There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.

I JUST got the diagnostic back on my car and it had the same code, P0440, come up. It means there was an evaporation leak detected. It can mean a few things could be leaking on your vehicle, down to as simple as tightening your gas cap.

Hope this helps!

No, this is not true for many different types of cars. Many times, the side that the handle is on the icon does not correlate to which side the gas tank is on the car.?æ

Generally, a check engine light is lit when there is a problem in the emissions or somthing that is affecting the effectiveness of the emissions.

It needs to set readiness. Which means you need to drive the car a certin amount of miles until the computer verifies the problem no longer exists. The problem will be in memory however you should be able to get it inspected no problem.

Don't fuel up with the engine running. The car is set up to test the intergrity of the fuel sytem for vapor leaks. The main time it will run is at idle. If it is running and you have the gas cap off, the light will come on.

Most likely the cause is a loose wire somewhere in the car's wiring harness related to the computer system that operates all of the sensors that operate on the car's engine. I had a 95 Elantra, love it went great, cheap on gas. Butone day the check engine light came on and then never left. It was always on, no apparent problems though then and 3 month later the car took fire. Total loss. Dont know if related but that's my story....

rectangular box with a smaller box on the bottom... bad explanation... autozone it up, they scan for free there should a 16 pin diagnostic port at the top left corner of your engine compartment, against the fire wall ...little grey box......

I am not sure what the question is. Error codes mean there is something not within specs for the engine to run properly. Oxygen sensor is reading too lean or too rich, tps reading too high or too low, etc. You can usually find the meaning of these codes in a repair manual for the model and year of the car. These manuals can be found in a public libary, bought at a auto parts store or a book store.

The code reader you used may not be advanced enough to read all codes or to pull stored codes. The CEL may light and then go off (even for problmes much more serious than a loose gas cap). Some codes are still stored. However, some are not. I do not think there is any rhyme or reason to this. Like most things on a Kia, the warning system is unreliable.

DON'T REMEMBER THE SPECIFICS, BUT FOUND 2 KIA SORENTOS WITH MISLABELED WIRING GOING TO THE DLC - HAD TO SWITCH WIRES INTO PINS ON DLC JUST TO MAKE IT COMMUNICATE WITH SCANNER.

you may have a bad sensor or lose sensor check to see if the wireing is rubbing on anything i belive if you have too much water in relation to antifreeze then the light wll come on, have your coolant tested at a service station to make sure you are using the correct ratio.
