Hey,
After changing the Downpipe on my 93 stock FD, I checked the ECU and got a 11 error code for the first time. (11=IAT sensor).
I was pretty astonished because I didn't touch the IAT's cables, and then I noticed I forgot to plug back in the DP o2 sensor. (shame on me)
I plugged the o2 sensor cable back in, and checked the ECU : the 11 error code disapeared...

I'm pretty puzzled now, can it be some sort of miswiring in the harness ?
the plug connectors are not compatible from what I see ( o2 :1 pin / IAT : 2 pin )... so what else ?
Just a coincidence ? anyway, in the meantime I've bought a new IAT sensor, so I'll change it tomorrow

 

That is weird. Yeah, you are correct - O2 is one wire, IAT is 2.

Could be possible the blinking light code looked like IAT but was the code for the O2 or something?

I double checked it, so I'm sure about this code. That's so weird.
Since I bought one, I changed the IAT sensor today, at least I'm sure it's OK now. I'll see if the code comes back later....
but before putting back the UIM, I need to solve another problem >> https://www.rx7club.com/3rd-generati.../#post12311711
Thanks Dale !
