95 tranny in 96, OBD problem. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

SaGang227 · 05-02-2005, 01:19 AM

I have a 95 manual transmission in 96 with 96 manual ECU and it is throwing me a CEL light.
I only hooked up speed sensor so I do not know if the light is caused by other stuff or lack of OBD II stuff.
Has anyone used OBD I transmission in a OBD II car?
Is there anything I can do to trick the computer?
95 ECU maybe?
I live in VA and I just need to pass the emission.
Thanks.

Transmission and wiring is identical for all S14s. Plug in the CPS and neutral switches, they're both required to keep the CEL off, has nothing to with OBD-II.

the 95 won't have the CPS.

Yes it will. My old 95 and three other 95s I've parted all had it.

So the CEL light should go off once I connect the neutral safety, crank position, and 5th gear sensor?

yep that will take care of it.

SaGang227 · 05-02-2005, 12:56 PM

Thanks for clearing it out.
I'm gonna hook it up before emission comes lol.

hey sounds kinda newb but..i just did my swap on a 98, and i'm kinda having trouble finding the crank sensor plug in from the top of the tranny, could you guys help me out, having trouble finding the plug in, don't remember unplugging it, any pics or details would help greatly

It's part of the lower harness, 3pin plug, pink, blue, and gray IIRC.

what happens if you have an s13 tranny in an s14 and there ain't no spot for the CPS?

It doesn't get hooked up.

but then you throw the CEL and won't pass the visual part of a smog check

Correct. Drill a hole and stick it in the bellhousing then.
