Okay, So I swapped the IM on my z6 for the y8.

I got in the car to start it and I got codes 10 and 14(IAT and IAC)
So i switched the plugs, disconnected the battery for a few seconds, reconnected it and went to start it again... I got the same 2 codes!!!
Didn't make any sense, so i switched them again and took out the ECU fuse for 20 seconds. Went to start it and, you guessed it, same 2 codes!!!
Did this quite a few times to no avail.

Does anyone know what's going on?
FYI: running complete obd1 with p28. I'm using the same IAT I had on the z6 IM and i mounted it on my intake pipe, and a differrent IAC
Please someone help

Probably swapped the IAT and IACV plugs around. They use the same style of plug.


Check the wiring. The IACV will have a blue and a yellow and the IAT is red and green I think.

Pin the plugs back to the ECU w/ a tester to make sure you have the right plugs. Also, pull the IAT and see if its melted. Ive seen that a few times, although Im not sure what caused it in either of the cars that it happened in.

you've seen an IAT melt? wtf?

yeah make sure they don't share a common ground either because maybe it got disconnected somehow.

me too. on RENR's car. that was interesting.

I know they share the same style plugs. By "switch them" i meant unplugged them and plugged them into each others male plugs.
As far as the ground... that would make sense cuz everytime I switch them neither works.
Where can I find the ECU pins for the IAT and IAC? anyone with that info?

HatchWarehouse

BTW The IAT did look a lil melted but is the same one I had on my z6 IM like I stated before. Never gave me any codes but I got like 5 of them so I guess it wouldn't hurt to switch.

Thanx for answering and keep it going

When i get home, I'll swap the IAC to the one I had before, check the grounds and swap the IAT sensor

HatchWarehouse

Okay, swapped IAC and IAT to the ones I had before and unplugged the ECU!!!!!!
Still same 2 codes.
According to my diagram, they do not share a ground so now i'll trace them to the ECU.

BTW, I did put a b16a2 Throttle body with its gasket. Could this be the reason I'm getting those codes?

Has anyone ever had this happen?!!

put your old sensors ont he Z6 maybe thats why is was sold

did you double check the colors on the plug wires.
