Code help!

[93 Fo SHO]

I posted this in the open forum also. I got codes 332 and 336 doing the key on engine off test. Could someone tell me what thes two codes are for? Any help would be great.

Here is a site with a complete listing of the three-digit codes.

332 (R,M) EGR did not open/respond during test or if memory code, did not open intermittantly - EVR or PFE

336 (O,R,M) PFE sensor signal is/was was high - ">PFE

The EGR valve may not be opening and the EGR pressure sensor may have detected a high exhaust backpressure (upsteam of the cats). (I though I had already replied to this topic).
