95 4runner OBD?
#21
Is there any type of kit you can buy to possibly prevent later headaches?
A 2nd Gen 4Runner or a 3rd Gen truck through 1995 is actually considered OBD, just it's OBD-1 versus the newer OBD-2. Domestics went OBD-2 as early as mid 1994 but 1995 was a compliance year for imports and Toyota waited until the very last minute to switch over. They even sold the 4Runner through IIRC July, the last of them being mostly 2wd Auto's, of which only like maybe 500 were released, special order only, of those, there's rumored to have been 50 with the 3.4 and R150 as demo or dealership special editions until they could complete the assembly line changeover..(way more to that story though, not enough to post here) with the official timeline being IIRC August 15th(?) 1995 when the first 3rd gen 4Runners began on the Japan line and the Tacomas on the Fremont, Ca (NUMMI) line.
**The rumored run of 50 2nd gen 4Runners (Gold badged Limited Edition's of course, full power, leather, etc-etc) are also rumored to have been the only initial 3.4 engines to not have the headgaskets installed upside down at the Japan engine factory. It was the stuff shipped to the 1995.5/1996 assembly locations that had the error.
History lesson over.

Welcome to YotaTech.
Well, let's see. You'd need a new, custom designed, computer. You'd need a whole new set of sensors. New harness. You might need to get the new system NHTSA approved, or you might be able to get around that. Then to get anything out of it, you'd need a code reader. (And you'd have to somehow verify your custom system was catching all the codes correctly.)
Or you can stick with what we've all got, and use a paper clip. (I'm not sure what you were doing for 4 hours; maybe you had to look through your desk for a paperclip?)
Is your problem that the CEL is intermittent? Most important codes are stored, so you can still read them even after the CEL has turned off.
Incidentally, you don't REALLY need a paperclip; any piece of wire (or gum wrapper) will work. Which is a little easier to find "on the trail" than an OBD-II code reader.

Well what I meant was instead of remembering all the codes and I already have a reader I can just keep in the car I had it in my 98 durango and has always helped me but the reason why I asked about if there was a way to just wire in one or bypass that cause I struggled the first time around with it I just bought it off craigslist and hadn’t done much to it yet other than remove weight fix trans leak and change a bad alternator. I just wanted to find out if going that extra mile for something to be quicker and a little less painful. Also took my 4 hours cause the guy had relocated the fuse box I needed to jump the 2 and when I finally got around to being able to do the connection I didn’t know if it was working because of the lack of knowledge I’m 19 haven’t worked on many cars and am still learning I’m not using that as an excuse but coming to a vehicle which I own and is my only vehicle now I didn’t want to destroy the truck by plugging 2 ends together with a paper clip cause our teachers at school totally recommended sticking a paper clip in an outlet! It was a genuine question thanks for the feedback I will continue to use the paper clip now that I’ve found where everything goes I marked both holes with a red sharpie and still haven’t figured out about the one code that pops on every other day for me the only thing it does is turn it on if it isn’t on and if it is on it doesn’t do anything else but turn off and turn back on once. I didn’t bother looking for what the flashes mean yet cause I don’t think that that is even a code. But thankyou for the knowledge I will use tomorrow as I go try again!
