OBD-1 codes and OBD-2 codes

[noclss2000]

I was reading that MC Spada wanted to make up a post for all the codes so everybody can see what codes are what.
Since I'm bored, figured I'd take it upon myself to do it.
These are taken directly from the Haynes Manual and a couple from "mike's PGT site" at http://homepage.ntlworld.com/mx6-uk/malf/malfcode.htm
The OBD-1 computer system was used in the 93-95 Probes.
To check for OBD-1 codes, use a paperclip and insert it into the 10 and ground pins in the diagnostics box under the hood by the battery. please make sure the car is turned off :roll: Once the paperclip is inserted, turn the key to the "on" position, but do NOT start it. Start to read the codes, quick flashes are single digits, and slightly longer flashes represent 10's or 100's. ie: 2 long flashes and 3 short flashes would be code 23.

This is where I go to research OBDII. :thup:
Its also where I got my list.

[noclss2000]

thanx rick.

Here is a link to the Mazda OBDII list in .pdb and .txt format. I abstracted all the codes and meanings from the .pdb file to the .txt file for simple reading, editing and or importing of the file.

Right Click and save as mazda.pdb (http://www.rs-productions.com/RSP_Motors/misc/Mazda.pdb)

[Forced 96 GT]

Hey,

I have a list from Autozone and there are differences in the list. I didn't go through the whole thing for OBD II but code P1170 on my list says: Engine shut off solenoid fault.

So which on is it...O2 sensor fault? or Engine shut off solenoid fault.

So if you had code P1170 what would you do? And what the hell is an Engine shut off solenoid switch... One of those things that have the Mitsubishi symbols on it?

[burncruisin]

How bout code 41 ... I think it's vris solenoid #1, but I'm not sure

Go to the website I posted in this topic and determine which codes are correct for your model year. ;)

[jws]

I also saw that 41 was the VRIS Solenoid #1, I was looking recently b/c I got the same code. I will post this question in maintanence, but anyone know how to/how difficult it is to replace that? The web site where I saw the code said it affects torque at 3250 RPM.

maybe its just because im a girl.. but you guys really need to learn how to post things like your talking to a girl that knows the basics about the probe... i know were the basic stuff is.. but what the hell are you talking about????
i have 95 GT and im trying to pull the code.. this is the only thread i can find with good instructions and i still have NO IDEA what your talking about... insert a paperclip in a 10?? whats that?? and were are these ground pins at that i plug into the diagnostic box??? speak with a little more thought that there is MORE THEN JUST GUYS ON THIS FORUM!!

:no: ahh i feel much better..
thanx for letting me vent...

Tessa

[noclss2000]

I can't get too much more detailed that what I did.
Under your hood behind your battery there is a 1" by 1" black box that says "diagnostics" on it. You open that up and there are female connectors as if you were to plug a computer to it. On the inside of the diagnostics lid there is a diagram that tells you what pins of these connections are what. One of these pins is called "10" and another is "grnd" these are the two you need to connect the paperclip to.

[PurpSpdRcr95]

ight .... the check engine light is sapposed to blink right? mine just blinked a bunch... and wouldnt stop.. is this bad?? how do i know what its saying... now if you could explain a little more on how to describe the blinks other then flashes... does the first blink count?? if so then it started with a long flash and then 3 short but it looks like when its done with the codes it goes back through and then the first one would only be 3 short..then then next were.. a long flash and 5 short and a long and 6 short, a long and 7 short. then it proceeded to do 2 long and 3 short... 2 long and 4 short. and then it went back to the begining.. . those are alot of codes im thinkin:???:... and im thinking alot of SH*T needs to be replaced.

:( :(

:( :(
long flashes count as 10 or 100, but with OBD-1 it's usually 10.
so if you read it correctly it would read codes:
13 15 16 17 23 24

may want to reset the computer by disconnecting the negative battery terminal and applying the brake for 10 seconds because I'm showing there is no code 13 but the rest seem to be pointing to o2 sensors and 17 is the egr. reset the computer and read it again, some may disappear.

[SteveS]

Well, its Saturday morning so I go out to the PGT armed with a paperclip and high hopes to see if I can sort out the "check engine" light which comes on occasionally.

Now the car is registered as a 96 PGT, but it was initially exported to Japan before being re-exported to New Zealand.

I checked the VIN against the Ford VIN decoder on http://www.geocities.com/ponch8725/fordvin.htm

VIN 1ZVLT22B755xxxxxx says its a USA/Ford Probe/Probe Passenger/belts and airbags/Import/Probe 2 door hatchback GT/V6 2.5L/1995/Flat Rock. Ok, so the car might have been shipped from Flat Rock late '95 and arrived and was first registered in Japan early in '96 - I can live with that.

But in the little black box marked "diagnosis" are all these pins and I'm looking for pin "10". Only trouble is the pins are identified by 3 letter codes in the black box cap. Across the top row are pins "FEN" "MAN" gap "TEN" and "+B". Next row is "GRND" "FAT" "FBS" "FVS" and "FSC. Down the bottom of the black box cap, under another double row of pins, is a code "H381".

I've got a couple of questions:

Am I looking for pin "TEN" to connect to "GRND" or should the pins be identified numerically, i.e. "9" "10" "11"?

Have I got a PGT made in 95 with a 96 diagnosis (OBD-2) system?

Can I identify the diagnosis system from the engine number, and where is that?

[Vseved]

10 was meant like TEN (Test ENgine). Please check here : http://home.golden.net/~trinity/

[Rocket]

I have a Late Build 97 GT. WHen I open the lid on the diagnostic box, there is NO diagram of what pins are what.
I am trying to set the TPS,,,,,,,,How do I know what Pins are the TEN and the Grnd?????????
So I went to Rick 96's page and saw his Picture of the Diagnostic box for a 96 gt. Mine is Completely different. I have female connectors in all different positions than his. Whats the deal? Where is the Grnd and TEN Pin? I have no clue where to look. Anyone have a clue?????????????

[DuCeTrUcE]

my cel used to stay on so i got code 24 and i changed my rear sensor near the firewall. now after its changed the check engine turns on and off constantly. i disconnected my battery to try to reset my computer but nothing still turns on and off when it wants to. it tends to turn off when i hit the gas and turn on when i let go of the gas. some days it even stays on for a long time then turns off. i know its the right sensor(bosch sensor universal) but why is it doing, i even checked my wires they are all connected properly, why is this happening please help!!!!!!:(

you have an obd-2, you have to have a computer to scan for codes and what not.

[mitchgt]

I have a 95 pgt, and when my check engine light came on about a month ago I took it in, and they said to replace both of my O2 censors, so i serached, and I found the (left one) and replaced it, but never found the (right, untill today). Autozone semmed to think they would both not go out at the same time, and that the shop I took it to was just giving me some BS b/c they couln't find the answer to the code.

So i go out side with a paper clip, and put 1 end in TEN, the other end in GRND... turn the igntion key to on and see no flashes. But i do hear clicks. From what I see here the flash should come from the Check Engine Light (CEL).. it just stays on never blinks. The clicks I hear seam to be 2 toned... such as TE-TA ::Second of pause:: TE-TA, TE-TA.... I guess I interpurt that as 24.. which is 24- Rear 02 sensor inversion error. So I guess i'll go to autozone and buy another 02 sensor. But before I did I wanted to make sure I was doing this right.

My CEL only comes on peridocally not at any certian point (besides that it never comes on during warm up only very seldom after the car has been warmed up) (Which would be the 02 sensor sence it doen't even send any feed back anywhere untill the engine is hot) Normally after it does come on it only stays on untill the car is shut off, then restarted.

whats everyone think?:wtf: :wtf: :wtf:

[noclss2000]

make sure you had the paperclip in all the way.
even if you dont have any codes, it will blink to show end of codes.
I went to buyoxygensensors.com and got both of mine for a pretty good price, they're oem replacement too.

Hey thanks a lot, I didn't think they would go in any further. :bow: Great thread, saved me 30-60$:tup:

[str8chillncuzz]

ok i did the paper clip code the first code read L= long S= SHORT....L S S and then L S S S S S S then it repeated the codes but this time it went S S and then L S S S S S S and repeats agian...do i count the very frist L that i got since that did not get repeated so would i get codes 12 and 16 or 2 and 16? Thanks

[GT1993]

ok i have a 93 gt and recentlly it just died on me while driving. everyting points to a bad distributor but when i replaced it nothing. now im trying to pull some codes but i cant get the damn cel light to come on. i did it before and it worked fine but now when i connect the ten and grn the cel light doesnt come on at all. as a matter of fact it never comes on.
Doesnt it come on when you first turn the key to ( this is without the clip connecting the ten and grn) ?

[jws]

No, you have to jumper 10 and ground, then turn the key. Don't start it, just go to the "on" or "acc" position. Should work. As for the problem, I'm not technical enough to advise, but if nothing works, then it does sound like it's electrical.

Thanks

?

Are you shure that it had started looping and it wasn't a separate code? Mine never put any sort of "prefix" in. My codes just looped the same every time.

No, you have to jumper 10 and ground, then turn the key. Don't start it, just go to the "on" or "acc" position. Should work. As for the problem, I'm not technical enough to advise, but if nothing works, then it does sound like it's electrical.

I know i have to connect the ten and ground to check for codes but i was just wondering is the cel comes on when you regualrry first try and start the car.

My bad. Yeah, I think it does. I'll double check.

CEL light comes on in the "on" ignition position, not "acc." It stays on in that position. If you crank it, the light is still on for a minute from passing by the "on" position, but then goes away. Hope that helps. I have an MX6, don't know if Probes are different in any way. Wouldn't think so.

When pulling codes, it will not light up, if you do not have a small enough paper clip to fit all the way down into each connector.(rember only use 1 paper clip and DONT cut it in 2 pieces)

I suggest just to do the fix for the first code(only becuase its easy to see where the 2nd starts, but after that its difficult) then after you fix the 1st code, reset the computer, and then see if you pull any more codes, and so on.... if you need more help PM me.

ight... half my stuff is fixed.. now my car is running some crazy codes...
i reset the coputer. disconnected the negative and pressed on the break for a little more then 5 seconds. the ran the codes again..
now it starts off with 4 long , and after that i get 6 short.
now i remind you i have an OBD1. what the **** kinda code is that?!?!? im not sure if there seprate codes or togeter. but i redid it 3 times to make sure i knew how to count. They look seperate.
anyone know what codes these might be??

[noclss2000]

hmmm, no idea
I looked through to see if there was anything close to it like 40 and 6 or 46 or possibly 460 or 406 and nothing. Just kick it, that always seems to help ;)
