oil pressure switch, EDIC relay, what!?

[lostmarbles]

I just called and they put Marv on. The part I bought is a 57010 unit. Let's just hope it fits. If not, I understand the only differences are the plug, which presumably could be swapped/grafted, if incorrect. Finding another one might not be so easy...

I haven't heard much about troubles with variations in the plug-in connectors so I think you'll be fine (but I have wondered about that myself).

...Is there any way to find out what markets/models/years got which part numbers? ...

In post number 16 you'll see GEN and ARL against that part number.

I think that means that it was supplied to the "general" (GEN) and "Australian" (ARL) markets.

But I haven't a clue just which countries the "general market" encompasses or what exactly the letters ARL stand for. (So I could be wrong.)



PS. I (like quite a few others) have my vehicle details in my signature line because I find it helps people reply to your questions (and also helps them determine whether your "cruiser-experience-input" into their thread is likely to be relevant to the problem they're trying to overcome).

For instance - Without spending significant time looking, I am unable to tell what engine you have here, where your vehicle probably came from, or what voltage (24 or 12) it is.

And before you say it ---- Yes. I know. - How can I offer you this advice when I keep "blocking" my own signature line so people can't see it? (I block it because I get sick and tired of seeing it.)
(But I won't block it this time.)

I am full of contradictions I'm afraid

Original relay 8/81 HJ60, Australian, on the LEFT. SOR replacement on the RIGHT.

Original Right, replacement Left.

Plugs are identical.

Guts, original.

Guts, original, note fxxxage...

That's interesting.

Looks like someone has altered the Toyota part number on your SOR EDIC relay. I believe it should read 28590-57010.

I wonder why they would do that?

Anyway. The big question is - "Does it work?"

 

[Tofudebeest]

It didn't work, but I never opened it to see if the guts were intact. I presume it is not merely the relay that caused the failure and ran out of patience and rigged a kill switch.

I'll assume you checked your oil pressure against an external gauge to determine it was within spec for the 2H. (Sorry, I have a 3B so I don't know the numbers) Having said that, did you try running with the FC (EDIC) relay in place, but disconnecting the oil pressure cutoff sensor? I might have missed something in skimming through this thread.

Somewhere around here I recall seeing a thread where someone made themselves a new oil pressure cut off sensor (sender?) because they were getting bad readings from it. I wanted to replace mine when I replaced my oil pressure sender, but SOR didn't have a listing for them. They did tell me they could probably dig up a used one to sell me - but since I was uncertain as to its status I decided not to trouble them further. So far so good, although I do have some funky pressure cutoff sensor/edic behavior occasionally when I get off the freeway - but I won't hijack your thread with that.

If you already tried those things, or are satisfied with your fix, then

so the problem wasn't the relay? I am having the exact problem, thought it was my relay, amd about to repklace it..if it wasn't your fuel control relay....what was it??

I don't want to pull mine out for photos-- but my EDIC relay was faulty at the relays themselves.

We soldered in new bosch relays, which now hang outside the metal box, and it works just peachy.

Those EDIC circuit boards are pretty simple once you really look at 'em. I'll bet some college student with some EE skills and spare time could make up new EDIC control boxes that are smaller, cheaper, and better .... if they wanted to.

Witch ampere is the bosch relays on? Regards
