Failed smog, hi NOX 900

Have 1993 940nt failing CA smog. Passed in 08 an driven less than 500 miles since(due to illness).Checked all codes - all okay, checked operation all things on OBD1 all work. EGR is working but not sure works at running temp? what is temp sensor reistance when Hot? Any other clues? Don't want to parts swap as most indie suggest. Not willing to invest more than $500.
