96 Nissan 300ZX - just bought

**SandW** · 10-03-2006, 03:27 AM

I just bought this 96 Nissan 300ZX. It reportedly had an engine swap from a lower mileage 96 300ZX. Ever since, the previous owner states the check engine light has been on. He hasn't trouble-shot it.

I don't have any special readers or whatnot. How can I read the code(s) that the car has? I know another car I had an operator could do a combination of key turns and count the codes. But that's all I know.

Also, after retrieving the codes, and ensuring they are valid by referencing a list (where, I don't know), how can I erase/reset the code to see if it comes back or maybe corrected itself?

If I can't reset it, can I simply turn it off somehow by cutting wire, disconnecting a fuse, etc?

thanks in advance! CA

Try Zcontrol, & Conzult...

OBD Scanners/cables come from Blatz or PMSL Developments.

Search & google for Z32 Consult software. There is a list on here somewhere of all the programs that work.

There are two ways to get the codes on the 90/96 300ZX.
Here you go:

You have a 96 OBDII but the 90/95 codes on OBDI means the same.

Does anyone know where the IAT sensor is or possibly has a diagram you can scan and email me? I read the ECU codes and P0110 was one of them. There were 4 others that must have been there from the original engine problems (or corrected themselves) because once I cleared them only the P0110 returned. P0110 stayed away (about 10 miles) until I turned the car off for pit stop but it returned after restart. Autozone said it deals with the Intake Air Temperature sensor--a $90 part from them. Not sure if I should replace it or troubleshoot other areas or if I can test it??? Anyone know?

The other codes that came up initially but stayed away (and I hope they stay away for good) were:
P0115: coolant sensor temperature malfunction
P0125: insufficient coolant temperature for closed loop fuel control
P0733: Gear 3 retio incorrect
P1705: don't know cause, Autozone thinks it is a manufacturer specific code and that only Nissan would know
Like I said, these codes didn't come back after resetting and I drove it for at least 50 miles afterward in the city and highway. The temp gauge is riding in the middle (mid of H and C) when hot and I guess the P0733 is a trans code--but it's shifting fine.
