OBS Ford Check Engine Light, trouble code reading one an OBD1 EEC4 System

- So I got a Check engine light on my 95 F 150 Flareside, well everyone knows about OBD2 First on Fords with EEC5 {electronic engine controle} but OBD1 is a lost art EEC 4 was the first true computer control system for Ford that did a lot of what the newer system's do today outside of streaming music and parking the car for you, but it did control things like air fuel ratio and timing along with other things' it came with an OBD1 port,{ I dont remember now but my guess is we just called it an OBD Port as there was no OBD2 yet} the port did the same thing and was shaped a little like an OBD2 but you cant hook up an OBD2 reader to it without an adapter, then you have to have a reader that will read an OBD1 system, I'll show you how to read the codes and maybe fix something along the way.
We get a 126 code and that's a MAP {manifold absolute pressure} sensor, I'll show you what it looks like and how to replace it, there really is nothing to it.
Dont forget merch, you can get that cool 10 MM shirt and always know where you 10 MM is, and ASG logo shirts as well at

You can get the code reader from amazon

And the extension cable as well

Good job sir ! Just purchased the same scanner and extension cable. Silly that they don't come together ! I've had my 1995 F150 just over a year, it is a pleasure to work on. Inline 6 , 5 spd I plan to keep until death do us part. No matter how pretty today's trucks are I like to keep things simple and affordable. Thanks for posting !
I'm with you on that completely
Fruit farm mechanic here...wow whole fleet of 90's & early 2000's units...I just started here & were kicking it off with a 93'f-150 - 94 E-van pickup really pissed off & van receiving new transmission..lol. I do have the Innova back to the future scanner /oobd 1&2 with the data adapters, got it for 150$ used E-bay. Great refresher info here & thanks.
Manifold absolute pressure.....lol
No problem
Now the cable is $45.00 on Amazon. Inflation at it's finest
A length of 2x4 or long srewdriver wedged between the seatfront and the clutch pedal works good, then I record the readings with my phone until all the testing is done - then I go sit down with a coffee and the reader’s manual and review the test
That's a good idea, Thanks
You can also run a jumper wire or paperclip from the single ground connection to the top right pin of the large connection (clip on top). Record or count the flashes of the engine light and write em down n look em up.
like so:

I thought you could do that but I couldn't remember how, thanks for that, I hope folks will always let use know when they more info that can help us, Thanks Tex
It just counts the pulses for you. More Convenient than watching the engine light flashes.
Thats right, you dont need one of these, I'm just lazy LOL
I've got a 90 f150 4.9 auto. Had running great but at idle 1.5 to 2 mins it had a hiccup. So minor I won't call it a miss. I planned on doing a fuel injection flush but hadn't bought the kit yet. My friend obsessed over the hiccup and sent it to a shop. When he brought it back it ran worse than before I changed the 10 year old spark plugs( that had welded them selves in the engine,) the wires, rotor and dist cap. Has never shown check engine light. After the shop had it I checked new plugs ( finger tight,) 5th new wire was pulled apart from the terminal end. I saw red paint drips all over so checked the balancer and saw they had slapped two red lines. One on the square notch cut out on the back side and one 1⃣ the tiny scribed line on the backside. The top timing marks on the gear cover were cleaned off. The bolt on plate with timing marks was filthy. I'm suspecting they timed it using the top marks and possibly the square notch. Both of which are wrong. On top of that I felt the gas pressure was low. I checked the pressure on the relief valve. Showed 0. Key on engine off several times and 0 psi. Started it and got 0 psi. Checked gauge on tire 35psi. Pulled line after filter and checked pressure. Key on engine off 10-20 times and got 30 psi. Left it for a while and it went to 20. Rear tank hasn't worked in decades. Going to make an adaptor to check pressure wo filter and see what it says. I think it should have 50 psi with the 4.9. I pulled the selector switch and found the plug was melted. I was surprised to see it is the front working pump and supply wire where the plug is melted and not the rear tank that is inop. If you have any tips or suggestions I'd appreciate them. Thanks
Sounds like your working on it, the Fuel PSI should be 60 on the 4.9 if it where a 5.0 it would be 30
@@AintScaredGarage I'm rigging a way to connect the gauge to the fuel line without the filter. I cut the input and output lines off the filter and will clamp fuel lines onto them and the hose manifold in my kit. Would the coffee can on the right inner fender leaking effect the vacuum on the pressure regulator? It has a bib broken. It is attached but not well and it hisses. I pulled the for hose off and no fuel but idle doesnt increase with me blocking the hose but it does a tiny bit when its sucking air.
I got my Innovo Ford code reader in today along with the extension cable. Plugged the extension cable into the code reader and something just didn't feel right. Pulled the extension cable off the reader and noticed that a couple of those broad, flat pins on the code reader had been pushed into the body. Now I'm a 78 year old former electronics tech so I know I didn't "muscle" the two together. I don't know if the female connectors on the cable were too tight or if the male pins on the reader body just weren't secured properly. They were pretty loose when I pulled them out with some needle-nose pliers. If the code reader body had been screwed together then I could have disassembled it and repaired the pins. But, it was glued together so back it went to Amazon. Someone mentioned an Actron 9690 code reader. I'll have to give that one a try. I'm afraid to reorder that Innovo Ford code reader. The next one might be as bad as the first one I got.
I have heard that, it seems to be a hit or miss thing, let us know what you think of the other one when you get it
My idle on my 95 5.0 was messing up changed the idle air control valve and that fixed it
Yes but there are some other things about the idle are controller, and in fact I'm going to address them in the next video, but I'm glad it fixed it for you, I put a new one on Strappy and it didn't really do anything, and thats because I had other issues I didnt know about, I fixed them and now it works great and does its job, Thanks
@@AintScaredGarage looking forward to your next video and thank you for sharing your videos
I bought a f150 last month and I cannot find the OB 1 port under the hood . It is not where yours is. could ford have put it in another area?
What year is your truck
Do you have the name and part number for that code reader you have? I need to check my codes on my 96’ F250. Thank you, great video. 👍🏻
I found one at autozone for $30. It’s an innova Ford OBD1 code reader. Sku#273350. Good luck y’all.
Thats it, in fact its a better price then I paid, mine was $38 from amazon www.amazon.com/gp/product/B000EW0KHW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
96 and newer OBD II
@@jgwalling some of the bigger ones, 250s, 350s, and 450s are still odb1 up to 98
Innova #3145
Will this work with a 91 Explorer 4.0l automatic 4x4 manual transfer case. Transmission won't go to 4th gear, and engine light comes on intermittently.
I should add, trans doesn't shift to 4th. Doesn't even attempt it. Stays in 3rd, doesn't kick out and slip.
Well it should read the codes as long as you have an EEC4 system
Diagostic question...if you run the KOER test and the testing unit reports 6 cylinders on a 7.5L 460 V8, is that a problem coming from the ICM, PCM, or off the engine directly?
I would think someone MAY have replaced the computer at one time and put the wrong one in, I would check the numbers on the computer to make sure it's the right one for your truck. So we got a lot of OBS folks on here maybe someone else has seen this, but I would start by checking those numbers
Perfecto 👌
I'm glad this could help, Thanks
I have a question my 94 f150 whit 4.9 motor on it after start driving the check engine light come up and feels like shakes a little ? By the way I'm suscribe
Well thanks for subscribing I really appreciate it, OK the first thing is to get the codes and see what it tells you, these darn things are hard to diagnose, i'm having a similar problem and will have a video on it, the forums arent much help it seems people do a zillion things to fix something and non of them ever work and then the topic just stops with no resolution, however you thing may be a simple fix, but first you got to get the codes, you can get a tester like I have or this is another way to receive codes without a tester th-cam.com/video/p04NPv_gXsI/w-d-xo.html
My 90 bronco 5.8 only has the big connector, I cannot find find small one anywhere near. I look so much just can't find it.
A 90 should be OBD1 and the one in the description should work, and if you search how to read cobes on a 90 Bronco you will find instructions on how to read the codes without a reader, you don't actually need the reader
I bought the scanner but not getting any codes even just jumping it and can't figure out why
You might want to pull the computer and take the back of it and see if you have leaking coroded capacitors, the computer may be bad or there may be a bad wire some where
I’ll have to get one
You can run them another way but this just makes it easier.
Where did you get the cable ? I couldn't find it on Amazon , they only have the adapter OBD1 to OBD2
i looked all over, im guessing they dont make em anymore.
@@jjg1501 thanks , I'll make some jumpers but it would be nice to have the cord .
I got the cable on Amazon here is a link www.amazon.com/gp/product/B000EVYH36/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
For some reason mine when hooked up makes all the noises and sounds like it's running all its tests but doesn't display anything on my obd1 reader which is identical too yours! Any help will be greatly appreciated thank you!
You might have a short or open wire in your wiring harness, or a dead computer, not sure
Are the pins pushed in on your scanner?
I sprayed throttle body cleaner in my throttle body and my truck 5.8 ford been popping and skipping ....I replaced my throttle body because the old one was tore up but truck still stalling and popping when acceleration
I would want to check the fuel pressure, does it do this on both fuel tanks? and see if you have any codes
Yes on Both tanks
What’s the carpet cover you have on the dash?
I got it on eBay 22 dollars, www.ebay.com/itm/264192553200 but I think there are better ones out there, all though I cant speak bad about it, it looks nice, this is the video where I put it in th-cam.com/video/ICuQsXzu-q0/w-d-xo.html
I could use some help with my old Ford truck I got, can I get some help? I got the tool but I'm not very knowledgeable on this tool.
How can I help you?
Help! My truck will not send a code , I have the same code reader.
You may have a bad ECM but without looking at it I cant be sure
It doesn't ever give you 111 unless everything is all right.
I haven't used it for a while but that sounds right
Can I use a regular 12 volt bulb to test for codes
I'm not sure, but if you put the computer in test mode one of the lights on the dash will blink, you can count the blinks to get the codes
@@AintScaredGarage thank you
Can you tell me what's wrong with my 92f150
I wish I could but these old trucks have so many computer and ignition problems you just have to start tracking them down
My 92 f150 runs but after a while it cuts out like it's running out of gas but if u stop and turn it off for a few mins it will run and drive for a little while then do it again
So off hand, the pickup in the distributor, the module on the left fender, the computer itself, wiring, there are a lot of things that could do it, they are temperamental, trust me mine has driven me nuts.
@@AintScaredGarage I think it's the fuel pump getting weak I found last night that is whining real bad you can hear it over it running
Where did you get the extension thing
While not a necessity it is very convenient to be able to take the reader into the vehicle, I got it on Amazon, heres a link www.amazon.com/gp/product/B000EVYH36/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
@@AintScaredGarage also thanks amazing video will be using this
Wait till the capacitors in the EEC start to leak, Ford used inferior parts, surprise, the EEC will need repaired as new ones do not exist, tho there are repaired ones available, requires a trade in, you need match the code on yours. Mine has no codes, runs descent, but is rich, fuel in getting in the oil, I have no idea what is causing it.
I had it apart and it looked fine, then anyway, if I put a V8 in I will do away with the computer
My 95 has that
This one is a 95, good luck, and thanks for the comment
111 means you passed with no codes
Thanks, I forgot most of that stuff I learned a million years ago and I'm having to learn it all again, truth be told, I didnt want a computer vehicle, but I kind of liked the truck, now I kind of love the truck, so again Thanks
😂
So is that a good cry or a bad cry LOL
