Engine light code 32 came on today
 

I have a 1993 Jeep Grand Cherokee Laredo with 5.2L magnum.

I was driving home from work today when my engine light came on. I checked the code and it is a 32. I believe this is an EGR code? Where should I start with this? Outside of just replacing the EGR valve, what else is related or could have gone wrong? No symptoms, Jeeps driving fine and everything seems the same.

Thanks.
