The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.

When the Check Engine light (or Service Engine Soon or small picture of an engine) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.

Use a Auto Scanner tool,fallow step by step reading process,take note witch code number "show" as defective,possible sensor fail, after replaces erase code using your Auto Scanner.Do it the same if another code number come out.

Unless you have a code checker with a reset switch, the easiest way to reset the light is just to remove the negative battery terminal for several minutes. That will usually do it.

Also, you don't actually need a code checker to pull the codes. With the engine shut off, you can quickly turn the key back and forth twice between the OFF and RUN positions. On the third switch from off to run leave it in the run position. The engine light will flash one or more two-digit codes. For example, if the light blinks twice, then pauses, then blinks three more times that's error code 2-3.

Check engine, vsc, track off light come on in same time

the vsc light comes on when ever the check engine light comes on, this is because the vsc cant operate correctly when engine isnt running right so computer shuts it down and light turns on, you need to have the computer scanned for codes to figure out why check engine light came on,the codes that are stored will point you in the right direction of the problem, autozone and other auto part stores will scan for free,

180,000 miles & check engine light is on. Already had vehicle checked.

the check engine light comes on whenever one or more of about 200 faults occur in the electronic engine or emmision controls, the only way to determine which system is causeing the problem is to have the system computer tested for the trouble code(s) that is stored when the light is turned on by the computer, which is known as the PCM

MY CHECK ENGINE LIGHT CAME ON LAST NIGHT AND I CANT FIGURE OUT WHY, I WENT TO CHECK THE SPARK PLUGS AND I CANT FIND THEM

ok dizzydean, u need to have the engine codes read. Most parts stores will do this for free, and will explain what could be wrong. They will plug a scan tool into a plug under your dash to read codes stored in the cars computer.
