What Diag Test Port to use on a '95?

Hey, Dale, this pretty much answers your question.

Note: If you have an OBDII port which it looks like you do, I would be hesitant to use the Diagnostics port under the hood. This is a jumper type connector, you jumper TE1 and E1 to flash the MIL and get the code, but I would call a Toyota dealer. Most will set you right; some will say, "Bring it in"...yeah right; I know one dealer that charges $99 just to hook into the OBDII!!!!

Thanks, hashiroku. Me too. And no, the MIL won't flash even if the pins - TE1 and E1 are shorted at the engine port. TE1 is not in the round underdash plug (as it shows in the sketch at the site you indicated) so I can't use that one either. So that leaves the other one nearby and behind the coin pocket, the suspect OBD2 socket. As for the Toyota dealers, well let's just say they weren't helpful. But could be for about $100. lol Personally, I don't think they are sure as this year of car was in some sort of OBD swap and they would have to experiment on my coin to find out - just a wild guess ;^)

Hey, by the way. I think another poster Jack was having a similar problem with his car. Wonder if he got it solved? Dale

Yeah, I saw his post and thought it was yours!

I had a '95 Tercel, and most people that looked at it (non-Toyota) were surprised to see the connector in the fuse box with the P-Codes. So it may not be OBDII exaclty (they ran it on the Dyno for emissions) but that connector will give you the codes. Next best trick (if you're in the US) is to head over to AutoZone and ask them to plug their magic box in; they say they'll do it for free.

Actually. as a Best Guess, you say the light is on sometimes and off sometimes? The ONLY thing i can think of that DOESN'T store a code is the gas cap! You may not be cranking it down hard enough to seal the system, or the gasket is going.

Good Luck!

Nah. The light is always on, unless I reset it by removing the EFI fuse. Then it just comes back on again after about 4 startups. I think I will get a scan tool for the car. They aren't that expensive and seem to be coming down in $$ as apparently the new ones use the new CAN protocol. Thanks again for the help. btw, have you ever used the AlldataDIY service? It looks like a winner to me. At least much more indepth than the Haynes book collection. I always found those books lacking in info. It prompted too many questions for which they didn't have answers, except, "take it to the dealer". lol Dale

The Alldata is good, but their commercial stuff is *expensive* !

There is another set of books out there, um, Bentley? Damn can't remember. They cost about the same as the factory service manuals, about $50, but assume you have a good understanding of mechanics, but not that particular car, and go in depth to the max!

Also, I think in a.a.toyota, I posted a link to how to troubleshoot OBDII without a scanner.
