How to know why the check eng turn on - 2000 Kia Sportage

You may need to send it in for diagnostics. The engine light on is letting you know that the PCM has identified a fault. This requires the use of a scantool to read the stored codes within the PCM. Code readers usually help but a larger scantool tends to be more informative. It is normal to see the traction control and brake light warning lights turn on when the engine warning lamp illuminates. Please let me know if there is anything else. Good luck.

The check engine light/service engine soon (yellow light) comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system u will seldom feel the car engine run any different, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

very poss it could be crank sensor ,broken wire ? timing belt? advise installing scan tool that reads live data check eng rpm on scan tool see if shows eng rpm while cranking , poss remove upper timing belt cover make sure is turning and not damaged, poss computer related problem or power to eng systems would have to check for power at fuel injs and check for ground pulse with logic probe or led test light if crank sensor ok also check for spark at plugs with special plug tester and check codes first

yes, that is called a "check eng" light, this may have came on for many different reasons, low eng oil level, low eng. oil pressure, eng. may be misfireing, eng. may be overheating etc. many things can cause this. get hold of a diagnostic scanner and scan for codes. or take it to any shop. theyll scan for you

coolant senor

if you havn't replaced the fuel pump yet that should do the problem

CHECK FUEL PRESSURE AND INJECTOR PULSE, IF YOU HAVE A NOID LIGHT. THERE IS A FUEL PRESS TEST PORT ON THE FUEL RAIL. KEY ON ENG OFF PRESS 35-45 PSI IF ITS A V 8 ENG 50-60 IF ITS A STRAIGHT 6. TO CHECK INJECTOR PULSE DISCONNECT THE EASIEST INJECTOR AND PUT THE NOID LIGHT IN THE CONNECTOR AND TURN THE ENG. OVER IF IT FLASHES YOU HAVE INJ PULSE. START THERE AND SEE WHAT YOU GET.

When your engine not starting or quits while you driving check to see any sparks, or remove the distributor and let the auto part test it. if it no sparks or the auto part say is bad , replace it.

55 is No Malfunction. Re-check the actual ECU lights for another code just to make sure. Let me know if you dont know how to do this. Hope this helps.

How is your transmission fluid? Check the level of your fluid while the engine is running.
