How To Read Honda/Acura OBD1 Trouble Codes

[@TheCapslocklol]

Just want to say thank you for explaining the process of reading the codes. I just bought a nice 95 Honda del sol, excited to get things lined out.

[@tongo117]

You are welcome.. Good luck with yours..

[@LynxStarAuto]

Some Hondas had an OBD 2 port as early as 1994. They were always ahead of the curve back then.

did you ever find out where the water was coming in the floor ? I have a 93 civic same issue.

Yes - kzbin.info/www/bejne/b3Xdp6Z3f7F9q9U

[@georgebowman3222]

Thank you for your videos on how to change out the computer. May it be assumed that as it is not shown or stated - that you do not need to have the newly installed computer - forgive me I cannot recall the correct term so this is what I can think of - to have the newer one "Rebooted" to talk to the car? This procedure, as you have shown are the ONLY steps to replacing a bad computer so the car will run again as it should? Thank you!!! Did you ever figure out what/where the water leak was coming from and why? I have the same issue and have to keep my (I call my car) skateboard covered up when it rains or it will get drenched depending on how much or hard it rains.

[@tongo117]

I did find the water leak:kzbin.info/www/bejne/b3Xdp6Z3f7F9q9U And I can't speak for all Accords but with my 95 there's no need to have the "new" used computed rebooted.. Just plug it in and go.. I have this video showing me finding used computers at a salvage yard:kzbin.info/www/bejne/oWfGf4aEnpWFa9U

[@buki86]

Do you have any idea, what code 55 is meaning? When it's cold outside, after the 1st start +3 minutes, and the engine stalling. 5 min resting, then starting again, run w/o problem. But I can not find code 55. Type: '99 Honda Hrv 1.6 4WD D16W1 - Thanks!

[@elzacatecano5096]

Hello thanks for taking time to explain us for me its kinda stressful to see what happens i have a 93 civic eg and i recently saw that there's some adapters to obd2 so it can be connected that port to the obd2 do u think that would work?thx

[@MeandThe93]

No ive tried it unfortunately doesnt work. Each obd is completely different from one another and pre obd2 ecu harnesses are manufacturer specific with their own scanner if im not mistaken.

[@elzacatecano5096]

[@luiz6089]

Hello mate. I'm doing the engine checking light as you did in the video but the light on my civic 1994 remain on (no flashing at all) if I turn on the car, the light still remain on. The engine light just turn off if I remove the jumper. My car run normally, no issues at all for more than 100KM with VTEC in action.

[@carribean660]

Did you ever figure out the water situation.I’m having the same issue 🙄(Passenger side by the ECU)

[@tongo117]

Yes I did.. kzbin.info/www/bejne/b3Xdp6Z3f7F9q9U

[@jamesward5721]

If you own an Accord that's '99 or earlier, chances are you too will only have OBD1 - they were built with the bracket installed for an OBD2 connector, but without the connector - you will have the 2plug blue OBD1 jobbie over on the LH side footwell. Search as you like, you'll not find "your" obd2 socket. You'll also probably struggle to buy an obd1 compatible scanner these days - please correct me if you know different.

[@giotru5978]

Very complete video explaexplanation 🙏🙏🙏

[@NecroNatty]

If the light just stays on, does not blink or anything, is that considered code 0 or 1? Thanks for the help in advance ❤

[@tongo117]

Never had that issue so I did a little research.. If you get a solid check engine light (CEL) after jumping the connector that represents trouble code 0 which could mean your computer (ECU) is bad.. Or, as discussed in this thread, the problem was a weak/discharged battery: honda-tech.com/forums/honda-crx-ef-civic-1988-1991-3/cel-code-0-a-2999474/

Hi...maybe you can help my problem..i have ligh code 36 what must i see? Its big problem to my honda? Any idea please

[@tongo117]

This list shows 36 as a Traction Control issue: www.hamotorsports.com/chenlicoditr.html

[@carn00b66]

I have a 96 Accord (non US variant, so still using OBD1), the Check Engine light turns off/disappears when the car and engine is turned off and on again. Basically, the CEL does not stay ON. Would doing this still spit out the code? I guess the better question is does it keep past triggered codes? The car should be turned off before shorting the pins, right? Doing that and turning the key to the ON position, I imagine the fault has already been "cleared" (?). The concern is it may not be giving me the codes related to the problem causing the CEL to turn on.

[@loriwelsh8988]

My check engine light doesn't come on until I have traveled two or three miles. How do I check the codes if it doesn't come on with the key turned as you have a demonstrated in this video? 1990 acura integra. Tia!

[@tongo117]

You can't read the codes unless they present themselves when ignition is on and OBD1 port has been jumped with wire..

[@indylmc]

We have the same car sort of. Mine is a European (German) model. Have you ever determined if there is an adapter for the ODB1 scan connector? I have an ODB2 scan tool and of course the connectors don't mesh.

[@tongo117]

OBD1/OBD2 adapters are available.. But from what I've read not all OBD2 scan tools can read OBD1 codes.. www.amazon.com/OBD2-Connector-Diagnostic-Adapter-HONDA/dp/B0053NRSN6#customerReviews

[@pennyhunter101]

Does obd one store old codes? Because my check engine light turns on then right back off. If I stop the engine with the light on will I be able to read it?

[@tongo117]

My check engine light is lit when I shut the engine off around 00:47 and then I'm able to read trouble code 14 with the ignition on but engine off.. So yes, the code(s) must be stored..

[@gabrielnascimento1021]

The Transmission D4 was flashing too, where can I read the codes?

[@tongo117]

If you have a 1995 or older honda you have OBD1 which means you count flashes of the check engine light.. If you have 1996 or newer you should have OBD2 and need a code reader to plug into your OBD2 port to then get your trouble code(s).. Flashing D4 usually means transmission related issue.. www.justanswer.com/honda/bb06g-i-ve-1995-accord-d4-light-blinking-i-ve.html

[@MikeKollin]

I have a code 14 for my 95 Del Sol. I replaced the IACV with a New IACV but it still does the same thing.... It's fine idles perfect when you first start it for about 6 or7 minutes... but when it warms up it starts to surge. When I turn on the head lights it stops... anyone know where I can buy a good IACV that doesn't cost $200 Bucks? I bought a cheap one clearly that didnt' work... anyone know a good place to buy one? Thank you!

[@dc-wp8oc]

Mike...any follow-up on this? Have a 95 Honda showing the same code.

[@MikeKollin]

@@dc-wp8oc Well for mine. What I found out is. Warm the car up, drive it until it starts to surge. Then park it. Open hood. and Unplug the IACV Valve. And if it runs perfectly then you know it's the IACV. It means it's bad. I bought a cheap one from China, $32.00. The good news is, this means you have isolated the problem to the IACV. It lets you know you don't have any gasket leaks etc, which I searched for by spraying for them and let's you know the engine etc. are working fine. So for me I just have to buy a better IACV, probably from Honda but they are expensive from them. The other thing you need to know is you have to completely #1 reset the computer / ECU, #2 then you have to idle the car for 15+ minutes or so until the Radiator fan comes on. So, you want the Radiator fan to come on, then let idle for 15 minutes more after it comes on! Then while it's running, just go for a 10 to 15 minute drive. Just drive normal down the roads and get on the highway for a while too. And it then is set. I did not drive afterwords, cuz I did not know this part, and was told that might be why it didn't' connect properly! So I am going to do this first!! This is probably why it didnt' work correctly. NOTE: TO reset the computer ECU, I was told to disconnect the battery for 30 minutes so the systems, ie stereo, clock etc. have to be reset and are drained... but I did it for 45 minutes and it didnt' completely drain systems. And I noticed they still were set at the right time meaning it did not completely drain the energy from the systems, clock etc... Now here is another way that is probably easier and quicker. Watch this video. #1 Reset Computer / ECU - I am going to do it this way next time (in Video) , then #2 Idle til radiator fan goes on then #3 then let idle for 15 minutes more, then #4 immediately take it for a 10 to 15 minute drive! This should reset it correctly. If you clean your MAF Sensor, you may need to do this. Not sure though! So if you clean your MAF Sensor and it goes funky, you probably need to reset computer this way! Hope this helps! P.s. Do not Rev the engine or touch anything like stereo or lights. In fact I wouldn't get in and out of the car except maybe once after you start it. Here's the Video: kzbin.info/www/bejne/a4G6dmqcZqqFfrc

[@MikeKollin]

@@dc-wp8oc I figured it out. Sorry I didnt' find this earlier... it was the idle screw. My former mechanic was playing a lot of games. Loosened up bolts on valve cover, oil pan, poured oil in air intake tube, rubbed it all over the throttle body on the inside and the MAF Sensor... He also completely loosened up the Idle Screw. It was barely hanging all the way out. Surprised it never fell out and lost it on the road... Once I tighten it up it all went away. The other thing I noticed is if you have a slow oil leak, if it gets to low, that can and will also effect your idle...
