Hello and welcome to just answer and allowing me to assist you.The malfunction light and check engine light are one the same just different terminology. When it comes on and stays on that means the ECU (CARS COMPUTER) has a bad input from one or more of it's many inputs. Without pulling up a trouble code it's any ones guess what is causing it. if it's a minor malfunction the ECU will go into what they call fail safe and take an average reading to keep operating things, during this you may or may not notice any or very little difference in how the vehicle performs but the light may or may not stay on that depends if it's a hard code or not.So unfortunately we cannot go further without a code to direct us which direction to go. Hope this makes your decision a little easier and if you require further assistance I 'll be happy to do so.

unfortunately yes because there are so many areas and inputs it's almost impossible to narrow down without a code,. sorry but thats the nature of the beast. If you need further help let us no.
