LOYALE 1992 ENGINE CODE DIAGNOSTIC HOW-TO?

Featured Replies

check engine light on on my loyale 1992 AT sedan. Unable to locate the diagnostic port/plug. It's pre ODB2 obvioulsy, not sure where to start https://speedtest.vet. thanks for suggestions!

More qualified folks will chime in but as I recall Loyale series uses the flashing system. Is the light flashing long and then short flashes ? 
 

Example would be two long then three short = 23 

Without looking at just from history I’d suggest it may be a thermo sensor or CO2 ... but I’m older and been off EA82’s for quite some time. 
 

Good luck. 

I can never remember which plugs they are - black or green. I think it’s green for EA and black for EJ, like I said, I can never remember. 

Remove the kick panel above the driver’s feet and have a pole around in the wiring. The plug colours are all that matter, from memory the wire colours in the plugs are different for the same plug colour ;) 

Then ignition ON, engine not running, count the flashes as moosens said. 

Look up a chart in a gregroies manual or fsm, whatever you have available and go from there.

Ahh the plugs ! Thanks Bennie .... I’ll go back to getting old now. 

The LED that flashes the code is visible through a hole in the ECU. . Bolted to the bottom of the steering column.  Remove the plastic kick panel to see it. 

Oh, if the code is a currently triggered one, it will be flashing while the engine is running and the CEL is on.  I rarely need to do anything with the connectors.

Correct me if I’m wrong please. But can you clear the codes by touching the battery leads ? while they are removed from the battery of course 

 

He’s going to want to know that next , yes ? 

Never heard that one @moosens. I’ve always just left the battery disconnected for a half hour or more. The overnight battery dance usually does the trick ;)

Since this is another one of those accounts that just posts once with a strange link in the middle and never responds, I imagine he doesn't care.

Well spotted Numbchux. I saw the link but didn’t think much of it as it seems relatively “normal”, just in a weird place. It’s the same for all of their posts on the forum, a whole three now.
