Check Engine Light

[240sx2Nur]

I was driving on my lunch break, and all of a sudden my Check Engine Light pops on. I have a KA24DE. Any ideas on what the problem could be and how to fix it. I already checked the gas cap. Thanks in advance.

Check the ECU for any codes.
There should be instructions on how to do that in the FAQ's at 240sx.org or try searching here. There is also a list of what the codes mean at 240sx.org i think.
