OBD1 Check Engine Light Fix
HTML-код
- Опубликовано: 13 сен 2024
- In this video I show you how to fix your flashing OBD1 check engine light (CEL) with absolutely no tools. This can be done without any fancy code reader with nothing more than a paperclip and access to the internet. This video will specifically cover code #32 and replacement of the manifold air pressure (MAP) and exhaust gas recirculation (EGR) valves on this 1995 GMC Sierra. The troubleshooting should be common for all 88-98 GMT 400 trucks (OBS Style).
I’m saving this video. And then liking and subscribing. Thank you so much. I’ve never seen your videos before. And this popped up just minutes after you posted it. I got lucky. Great information
Heck yea! I love it when I can help someone out. Thanks for the view and the sub!!
Your the best bro thank you 💯
@@raymondrodriguez809 i appreciate you watching!
What can’t you do with a paper clip and access to the internet??
Lol the internet is the key part of this equation i think
Thanks bud
How to reset? Did some work & tried unhooking the battery
What do you do if the part you put the paper clip into doesn’t work right? I put the key( I have actual GM key for that port) and it flashes the 12 but then it dies and flashes nothing. How do I fix it?
👌 awesome, how to get those book codes? Thanks.
Can you list the parts
EVERYBODY I see online that does this their vehicle is a GM!!! I wonder if that makes any difference. Just wondering. Its a good video though!!! but really you can get some codes on 1995 vehicles just by turning the key to on 3 times.....on the 3rd time it starts blinking the codes.............what i dont know is if you get any additional codes with the paper clip.
I cant get mine to work on my 1990 silverado with a 6.2 Diesel, wonder if the lamp is broken? Or if the wires are cut somewhere
Yea that is odd. Id think the light should come on with key on so maybe bulb?
Do you still own the sn95 cobra?
I do not it is sold. Last i saw it was up for sale again. Ive got a new Mach now
did this fix it? im getting the same code only with highway driving. i’ve replaced every sensor for preventative maintenance but have yet to do the map or egr so i might as well do both now
Its been a minute but yes i believe it fixed it for good. Best of lucj
@@truckandroll989 👍 thank you bro
Will the check engine light automatically go away after it’s fixed and driven a lil or does it need to be reset
It should eventually go off or you can disconnect the battery
It should eventually go off or you can disconnect the battery
I have a 1996 GMC Sonoma 4.3 L what pens did you jumpER out in order to read the fault codes
Youd likely have to look it hp for a 4.3 im not sure. My video was just for the 5.0 and maybe 5.7
Also 96 is obd2 and not 1. Gotta use a code reader.
It shows 1 n 2 3 times let ya know its working looking for code if so comes after
Saw this after doing the same thing replacing the EGR and AIC (didn't replace the map sensor ) because of high idle on 94' Yukon. Check engine light has been on for 15 years, lol. Did bring the idle down to 800 from 1100 after changing the sensors, but I get code 32 and 35, which are the sensors I replaced? and check engine light still comes on?
Its possible you still have another issue. High idle could be a vacuum leak. Can you clear codes and see if they come back? Also cleaning your intake is always a good idea. I pulled my TBI and cleaned everything. Last i guess you could always try and replace MAP
@@truckandroll989 Thanks, how do you clear the codes? unhook the battery?
@@pcdubya im sure there is a way to with a scanner but yes unhook the battery and let it sit for a few minute. If the code is still needed it will come back.
Sometimes the check engine light comes back on until you clear the codes. If you clear the codes and the check engine light comes back on,then you havent fixed the problem.
My dad bought a 98 c3500 6.5 diesel with 230k(we bought it with 227k)on the dash and I was wondering what do the check engine lights on those trucks come on for?(low oil pressure, bad thermostat, etc)....cause since we bought it and brought it home a couple months ago the check engine light has been off all this time and the bulb for the check engine light works(it comes up when you turn the key on)can you tell me?
So yours is a 98 so it is obd2 (unless diesels are special) which means it has all the standard codes of new cars - its the same plug. 95’ was the last year for the style you see in this video. Its normal for the light to come on when the key is initially on for a second. But if it stays on it could be any number of things. Best to get the code read to see. If the light foes out after a few seconds you are ok! Thanks for watching
What pins on the port did you plug into
There is a good diagram here. Top row upper right two pins. Shown as A and B on the link below.

How do u come up with 32? I’m confused on the counting
It will flash a count of lights at you between the 1 and 2 flashes letting you know the beginning and end of codes. The first digit it flashed was 3, the second was 2. Combine the digits for a diagnostic code of 32.
where do i get the code book or the numbers???
Your best bet is to just Google the codes for your year and model. I was able to find mine pretty easy online
Mine won't come on
Which terminals do you need to short for an 89 chevy 1500 pickup?
Thats probably a google question sorry man
same ones. 88-95 1500 GMT 400's are OBD1. 96 through 98 are obd 2. use a low amp mini blade fuse it works perfect.
How come you look like I saw you in 1980
Likely cause I was alive then
😂😂😂😂🤝
This shorts out the computer, I don’t recommend this. Maybe in a pinch. Just buy an OBD1 reader
Eh I dont think it is doing any damage. The cost of a paperclip vs the reader and the expected # times you will do this makes the paperclip option a no brainer for me. I also wouldn’t be surprised if the reader is doing the same thing but displaying you with a code.
What are you talking about? This is exactly what it is supposed to do.
