Code 91-2

I have a code 91-2 coming on very intermittently and was wondering if anyone knew what it is for. I can re key and all is well, i just want to make sure there isn't something I should take a closer look at before a catastrophe occurs! It has a GM 4.3L engine in it. Lift serial number is R005V02227K.
Thanks for the help.
