What year S13 is your car? I believe on 89 S13's the Engine Coolant Temperature Sensor was wired in via a metal tube thru the lower radiator hose. The sensor screwed into the metal tube that was part of the radiator hose.

Your high NOX is due to no vacuum going to the EGR valve. Check the rubber vacuum lines that hook up to the EGR & BPT valves. The BPT valve has a short 3 inch vacuum line underneath it that usually cracks & melts due to underhood engine heat. If that line cracks/breaks/melts then you won't pull vacuum to the EGR valve resulting in high NOX readings. I seen it happen on several S13's & S14's cars I've worked on.
Anyhow...hope this helps..
