95 Ford Explorer XLT 3.0 V-6 Auto 137K

Late year build because it has the OBDII system in it.

My "check engine" comes on about 5 seconds after start and stays on the whole time the ignition key is on.

Autozone reader gets "Link Fail" on every attempt to read the codes.

I'm new to OBDII, where should I start to troubleshoot?

 

If your Explorer is a 95 like mine I'm betting it doesn't have one. I did the same thing when I got a CEL code, but I don't think they started putting ODII into Explorers until the 96 year, the dummy port was just included with the redesign in '95. On my 95 Explorer it is OBD I. Look under the hood near the drivers side firewall, next to the PCM should be a plug the says ECC Test, that is where you want to put a code reader. If the Autozone is nice they will scan your OBD I codes also. Hope I helped.

 

Thanks BigWillie, I'll check.

A dummy plug, who would have guessed. Explains a lot.

Thanks

 

no problem at all 96ironman, let me know how it all works out for you.

 

its an odb 1 for sure. its the old type that blinks they actually suck but you gotta do what you gotta do. The sticker under the hood will tell you if its obd I or II. I have an a 95 eddie bauer exploder

 

'95 was the transition year for OBD I/EECIV to OBDII, so they all have the OBDII port under the dash. I've never seen one yet on a 95 that wasn't a dummy port, as they all seem to only work off the EECIV under the hood.
