1996 Nissan Frontier

It's 4/22, I'm not sure you still have an issue as it's been over a month since your post. If you do, I'm not sure what your question is. Do you have access to info on code p0443? Are you looking for info on this code, & diognostic procedures? I can tell you that p0443 is EVAP control system, purge valve C fault. Now you need to begin diognostics for that fault code. I reccomend renting "Mitchell 1" service manual for procedures. They have all the info you need to diog. & Repair
