hey,
this is for orion, but anyone else is welcome to chime in.

i got 2 codes and i havnt picked up any service manuals yet because i just got my car.

can someone point me to the website that has the codes. i have 83 and 122 but i would like to know them all. and which manual is best? i havnt looked but u know chiltons, haynes, or FSM? i figure FSM is best since its probably most complete. money is no option on that part.

TIA

go to www.240sx.org (http://www.240sx.org) and review the faq you have the sohc so go to troble codes for the sohc.

Dan -

The list on my website ( http://plaza.ufl.edu/briand/ECU%20codes.htm ) doesn't have 83 or 122, and I think it's pretty comprehensive...?

I used the 240sx.org list, one from the resource quoted on my site, and another as a check...and no 83 or 122 on either list.

Maybe run the codes again - Instructions can be found at the link above - and see if the codes read the same...?

Anyone know? The car is a '98 and just turned over something like ~59,000 miles...is this some BS to make you come in for a 60,000 mile check-up?

Thanks - Brian

Dan, code 83 is the absolute pressure sensor, couldn't find a 122, but that's close to the transmission codes, so maybe it's in there somewhere.

Just wondering where you found this info, and to what years does it apply? There's no code 83 in my FSM for '95...

And what is an absolute pressure sensor?

thanks- B

That's b/c the absolute pressure sensor wasn't on the OBD-I vehicles...

It is part of the OBD-II emmisions stuff.

It's used to measure the pressure in the intake manifold...(and Hondas use it to determine air/fuel ratio, it's why they need to up fuel pressure when I/H/E is added).

I'm sure someone else can explain it better.

It's used for diagnosis only. It detects ambient barometric pressure within the plenum, and is regulated by the MAP/BARO sensor. I took mine off along with everything else OBD-II with no ill effects.

thanx guys.

so russ if its acting up, it is nothing major at this point in time other than lighting up that damn dash light?

brian-if somehow we counted wrong and the 122 was 121 or 123 it would be the Shift Solenoid V/B or Overrun Clutch S/V.

i do know my 1-2 shift seems to have small 'clink' in it. for now im fine i might be getting a new clutch soon. thanx again. im going to run them again today after it gets back from the alignment.

Nope, it won't effect driveability at all. Same with several other sensors on the car, they just like to "see" if everything is running as economically as possible. What I've found is the economy suffers anyway at 6000 rpm. http://www.freshalloy.com/ http://www.freshalloy.com/

Dan - The shift solenoid is for the auto tranny (I think), and don't know about the other...but I think we were right - 122.

I can install it...cheap. Let me know if you need my help.

Get a 95 ECU and you can ditch all the OBD-II, you'll be happier without it, as will the engine. Don't let Brian work on your car either, you've seen his, right? http://www.freshalloy.com/

thanx guys.

brian i only meant get a new clutch if the TO bearing was bad or if it turned out to be a clutch issue but i think im fine for now.

i would get a 95 ECU but i dont think i will spend the money on that to maybe a year down the road plop in an sr20 but you can use the 95 ecu for that correct? hmm. what kinda stuff can i strip off if i get the obd-1 stuff. i know you (russ) took alot off but i wont have to change anything other than the ecu and then cutting off sensors and etc.

also keep an eye out brian for an extra a-pillar hehe i dunno if i wanna drill in mine.
i also have people who are interested in drift from tampa, lots of japanese guys who used to live there theyre really good!

KA ECU won't run an SR, so it's not a "plop" in, but you can probably find one cheap until you swap, then sell it. You can take out a LOT by going to the 95, giving you a lot less stuff to worry about. The light trips with emissions related stuff more often than not, so by loosing all that you'll get rid of the possibilty to see the light.

Always talkin' sh!t, huh... http://www.freshalloy.com/

Anyway, I'm good at clutches now...done 4 S14's plus a tranny swap in the last year - So I can't be too bad!!!
