How do I pull CEL codes on a 94 Galant?

**89Mirageman** · 11-23-2006, 10:47 AM

I've searched all over for it. I'm assuming it's OBD1 since it's a 94 but the connector is different from the 1g DSM's that I am used to. The car runs perfect so it's probably something minor or emissions related but I'd still like to know what is causing it. Any help is greatly appreciated!

94-95 have obd1 computers but have the obd2 connector and you need to either short it to get the codes or go to the dealership

How do I short it? Which pins do I use? Will the CEL blink or can I use a volt meter and count the sweeps?

CEL will blink and i dont know how to short it as i need to do the same on mine, theres a thread i posted on here about the same thing and there was someone who said they were working on figuring it out but i havent heard anything else about this.

yeah, good luck buddy. i've been trying to figure this out for a while and the only way to pull the codes off my 94 ES is to got to the dealership....and find out a way to not pay the $70 JUST FOR PULLING THE CODES

Wow, this sucks. I found this site online but it doesn't seem to be much help.

Maybe someone else can figure it out.

It tells you how in the FSM and in the HAYES MANUAL. I gotta look but i know for a fact you suppose to short 2 pins to get the CEL flashing.

If you would look and tell us which two pins I would greatly appreciate it!

OK,

locate the plug socket,using a jumper wire, ground terminal pin#1(located in upper left corner).
After bout 3 seconds the CEL will start flashing out the codes.
First it will flash in the tens place. then it will flash the units place, For example.....

the cell will light for 1.5 seconds, then will go off for .5 seconds, then will light again for another 1.5 seconds.

If you know how to read the flashes and the pauses then you are good and I need not write anymore. If not then PM me for a copy of the instructions.

ALSO, there is a post with the codes listed somewhere on the forum if anyone wants to search for it.

Thanks for this info!!!!! I got a code 43 for the EGR system. Probably just needs to be cleaned out. Thanks again...

**bronxbombr** · 11-25-2006, 01:14 PM

Glad i could help and pass the knowledge. Maybe someone should make this a sticky with the error codes posted too.

**mitsueclipse2019** · 11-25-2006, 10:40 PM

wow someone finally did it thats crazy well i know what im going to do :P, but i do have a quick question, what kind of wire is a jumper wire?

any wire that will not burn out should be good. Like a test light wire or something.

ah ok thanks man, im def gonna look into this right away, i have another question if you dont mind, now i know to ground terminal pin#1(located in upper left corner). but what would i ground it too? and sorry for these questions but i dont know much about this kind of thing

I took a small paper clip and straightened it out and stuck it in pin # 1, then I took a short jumper wire that I fabbed up a while back and you clip one end to the paper clip and I just grounded it to a bolt head by the pedals. Anything metal that screws into the chassis will work fine. For the jumper wire I just took a short length of wire (about 2') and soldered a small aligator clip on each end.

The link I posted above will show you how to count the blinks and it also has a place where you can punch in your code and it'll tell you what the problem was. For instance mine was a 43 which was the EGR valve. Probably just needs cleaning out or something since the engine has 155k on it.

**mitsueclipse2019** · 11-27-2006, 05:11 PM

would speaker wire or telephone wire work as those are the only types of wire i have around at the moment

**eksz** · 03-15-2007, 01:22 AM

Any wire will work. 89Mirageman's suggestion to straighten a paperclip and attach a wire to it works geat.

The following copied from "Car Problems? 7th Gen Only" topic "electrical problem/On Board Diagnstics (OBD) plug problem"

This the OBD2 plug with a few of the position indicated. Our 94 and 95 cars are equipped with this 16 pin OBD2 style connector but have OBD1 type diagnostics which means you can't use an OBD2 code reader to read the error codes. Instead on our 94 & 95 models you ground out position #1 and count how many times the Check Engine Light (CEL) flashes to determine why your CEL is on. (Haynes manual chapter 6, page 6-5 for details),

pin 16 +12v power
pin 5 ground
pin 9 8192 baud serial data
Pin 1 ground out to determine error codes on 94 & 95's

I've found this in my efforts to find out what a code 11 is (O2 sensor) on my 95.

I hope this helps anyone out there looking for codes for our cars. If it's not a help, a mod or I can delete it.

You do not need going to the dealership, I wrote it a few months ago here https://www.thegalantcenter.org/view...693&highlight=
You can datalog 1993+ models including those with hybrid ECU with EvoScan http://www.limitless.co.nz/ and Mitsulogger http://www.aktivematrix.com/
