03 Honda Accord Check Engine light came on... Timing Belt service reminder?

i would say no something else is wrong,unless there maybe a timing warning but with those miles i doubt itcheck your basics,water oil etc check belt tensionsif alternater gives erradictcharge this can cause a fault code.check engine sensors,make sure all are plugged in ok.check vacuum lines for leaks.mainly over inlet manifold end as this is the hotter end of line which caused rubber to become brittle and splitcheck exhaust ,make sure no damage has occuredie crushing of pipe.check fuses with test light to be sure they are all ok.to do this find a good earth/ground for wire on test light,door hinge or ignition key if inside car and touch both sides of fuse to make sure fuse ok,under bonnet use neg battery terminal.if this doesnt show a problem i reccomend buying a workshop manuel .this should give step by step instructions and other fault finding tips good luck with it.dont let it beat you
