obd emmissions code reads 2-4-1/erg 850 1994

Hey folks,

I'm new to the 850. I've owned a 940 for 7 years and has done me well. The 850 certainly is different but when I need to get somewhere fast I love it. Anyway. The check engine light came on the other day. I checked the obd and came up with nothing but 2-4-1 in the emmisions system which is the EGR system flow faulty. One of the hoses had come loose. Would that be enough to cause the problem? Also, how do I reset the check engine light? Any help or suggestions would be great. Thanks.
