z31 ECU trouble code 23

[Austin M]

Hey guys im new here but I am on my second z. I've got a '85 300zx non-turbo throwing code 23 and 31. I know 31 is for the A/C but will this shouldn't hurt smog right? Now code 23 is for the idle position switch correct? I tested the switch and it seems to work fine. Is there anything else under this code? And what pin on which connector to the ECU is connected to the TPS?Thanks
