95 lesabre did the paper clip trick to read codes now the heater and radio not workin

[scrapdaddy]

1995 buick lesabre.. I tried the paper clip trick to read codes on the check engine light I had.. I ended up getting a spark and now my heater and radio don't work.... turns out I didn't have the proper obs port to do that trick on....I checked the fuses they are fine... could it be a relay??? I found the relays but they are not marked to tell me which relay runs which component... is there a way to test a relay with a multimeter???

any help would greatly be appreciated..

thanks

In 1995, the LeSabre was OBD 1.5, which means it was still an OBD I PCM with an OBD II connector. If you got a spark from the terminals you jumped, you must have a blown fuse. Codes on the '95 can not be read with the jumper procedure you need an OBDI/OBDII capable scanner. Do you remember what terminals you jumped??

 

[scrapdaddy]

no I don't remember what terminals I was kinda trying them all

I have the same car and did the same thing. You cannot do the paperclip trick on your car. I blew a fuse and you probably did too, you just have to look very close. To read your codes, you need to have a reader referred to as a Tech I reader (very expensive) which has a lead coming from it that plugs into the cigarette lighter which gives the reader power. Although you got a spark from the connector, that connector does not provide provide power to what I call common readers which are more likely to work on a straight OBDI or OBDII vehicle. I did search out a garage that had the reader and he did a free read. I won't mention the name because I don't know if I should believe him or not since the stuff he read (3 codes) and he sells stuff and repairs, you know what I mean. None of the auto stores in my area were able to read the computer because they did not have the equipment. Lately, I was able to get a reading by O'Reilly Auto Parts who must have upgraded their readers and they do it free as well. YOU DIDN'T SAY WHAT IS GOING ON WITH YOUR CAR. Try me.

All OBDII ALDL connectors have 12v power on pin 16, as shown in the attachment. You do not need the optional cigarette lighter cord for a power source on these vehicles using an OBDI/OBDII capable scanner. In addition, you do not need a Tech I scanner (expensive) to read codes on the '94-'95 LeSabre, or many other models with this same configuration. I have used an Actron CP9150, CP9190, Matco 9640B & Matco 9001A on many '94 & '95 models all of which do not require the additional remote power supply. The earlier 12-pin OBDI connection does require the remote power supply when using a scanner.

it turns out I did blow a fuse so the radio is working again... but now I have a unrelated problem....the car wont start...it runs for a second then dies....

Does it have an OBD II scan port? If it does now would be the time to hook a scanner up to it, OBD I scan tools are a little harder to come by, If it's OBD II most places will tell you there OBD II scanners only read on 96 and newer models (why I don't know). Have you checked the fuses under the hood? What problems where you having before you stuck a paperclip in places it doesn't belong? Not to scare you, but I'm not gonna promise you can't fry your PCM by doing what you did. It could've just blown more than one fuse. Hopefully that's the case. Will it stay running if you give it a little bit of throttle after it starts?

 

[scrapdaddy]

Yes it's a obd 2 port. Last time I checked it with a borrowed code reader. I got the code p0733 code which is a tray issue. Could be the tray is effed. Or some sensor. Today I was playing with it. And I was able to get it fired up. I did have it parked for 4 to 6 months. So maybe the starts and dies issue is bad fuel? ?? If I Rev it up to high it will die. But fires back up now. Or at least today it does.

 

[HotZ28]

DTC P0733 is an "Incorrect 3rd Gear Ratio" which means you may have a problem with the trans, solenoids, or the ECM/PCM. Have you driven the car enough to notice erratic shifting into 3-rd gear?

 

[scrapdaddy]

no I haven't driven it enough to notice anything..... it died on me once....I was able to limp it home... it was parked for 6 months...then I drove it again.....and it died on me again and It had to be towed home... its been parked since... don't trust to drive it again.....im thinking my issue of running for a second then it dies might be a old fuel issue.... as for the tranny... id love to have a video or pics with a breakdown of how to change the solenoids or what ever issue I have with this code

Old contaminated fuel is possible, but have you checked fuel pressure & have you changed the filter? If you disconnect the MAF connection, will the engine start & run better?

 

[scrapdaddy]

I disconnected the maf and the car fires right up.. revs up then idles right down too low... idles rough and wants to die but doesn't......with the maf connected it will only run for a second then die....haven't checked filter or fuel pressure

 

[HotZ28]

You need to replace the MAF sensor, which seems to be the problem from what you described.

 

[scrapdaddy]

do you think cleaning the maf would help without replacing it?? I live in a small town so parts are not available right away..... and do you know of any ideas for my p0733 code?? id like a break down with pics or a video on how to fix it..

 

[ryenie]

You can try cleaning it and see what happens but there is no guarantee that it will fix the issue short term or long term. If you do attempt to clean it make sure you get a spray cleaner specifically for MAF sensors. Any other kind of cleaner can damage it or leave a residue that throws off the reading.

Do you remember which fuse? I am having the same issue
