Just what I was looking for. Paper clip hack much narrowed it down. Got code 54. Fuel pump circuit low voltage/EGR valve solenoid 2 error. Time to jack up the Van. Thanks Brother.

Thanks for the video! Now I know the O2 sensor has a problem (code 13), on our 1992 Chevy S10.

keep in mind that these older obd1 systems are not as accurate as a modern obd2 system. just because you get a code that says you have an o2 sensor problem, don't assume the sensor itself is bad. a dirty air filter, an exhaust leak or a clogged egr valve can all set an o2 sensor code on an old gm vehicle. also, code lists not only vary from model to model but also year to year, and fault codes may have a different number.

Man... This video saved me! The parts stores and repair shops no longer carry/have OBD1 scanners anymore. I had a shop tell me they can't scan my car, but can fix the issue. I asked them how if they don't have a scanner to know what is wrong?! Now I have at least a general idea on where to start. I already have a parts car, so just a lot of trials to swap out to fix the problem.

Thanks to you sir for your informative video.Really helped me out on my 95 GMC SIERRA.

Thanks for the help. I guess I used to know this back in the day. Haven’t messed with these year models for a long while.

Very helpful video with all the points covered. Thank you for this

Dude thanks so much just got a 1992 gmc SL 1500!! Appreciate ya!

thanks for the clear video and instructions. I knew I could jumper an obd1 but I couldn't find any info on how to do it.

Thank you so much for this...can't wait to see what codes on my 95 s10..greatly appreciate this information

Does your s-10 have the newer shaped obd2 plug or the rectangle. wondering if it worked for you.

@codys9601

Try to find forums for your year make and model on Google for wiring diagrams or any information regarding the prongs in that OBD port....If you have an obd2 tho I believe your better off getting a cheap scanner that gives you diag readouts

On the top right of the connector, connect the two pins (top right 1 and 2). There, you saved 8 minutes.

thanks for the help.. i'm from portugal and i have a gmc s15 jimmy from 1989

For anyone who has a repeating 1.1-2 code after the initial three, that indicates you have no codes to read.

My truck has a small misfire at idle I've been driving it like that for about 8 years I'm tired of it I have no codes never gotten a check engine I pass smog i live in California I have rebuilt the tbi ran fuel injector cleaner changed the fuel filter twice changed the distributor spark plugs and wires I just can't figure it out I gets worse as the truck warms up, when it's cold start it sometimes misfire like every 5sec maybe 10sec, but once the truck reaches operating temp my passenger seat is vibrating like crazy

After it showed code 51 three times it would go onto the next code instead of that one to one two (1-1,2simply means the test is over) if there was another code after it showed code 51 three times then you would count the flashes again and that would be the second code when all the codes are read it will flash that 1…1,2 to showing you the test is complete

thats all I got is OBD 1 vehicles...the paper clip is useful but I got the actual key for the A and B ports...
