IAT sensor code 10 - Which wires goto where?
Engine: D16z6 w/ basic bolt ons (OBD-1)
Code thrown: 10 (IAT Sensor)
I took it out for the first run after replacing the head. I had a Code 10 pop up after 15 minutes of driving. The engine felt a little sluggish after it popped up. Most likely, it is running rich and the A/F ratio must have been messed up due to the sensor.
I measure the voltage between the terminals on the IAT and came up with .8 k ohms. Which might be a cause of it.
However, on my DX coupe swapped with a D16z6. The wires that connect upto the IACV, IAT, and the Evap purge sensor (directly top from IAT sensor) are a bit different colors then the Helms manual.
IAT sensor: Black/Yellow, Red
IACV sensor: Blue/Yellow, and Black/Yellow
Evap Purge sensor: Pink/Blue, Black
=\ I hope i didnt fry my IAT

never mind - looks like on my setup. the IAT and Evap Purge solenoid sensor was swapped.

IAT: Red/Yel, Grn/Wht
IACV: Yel/Blk, Blu/Yel
EVAP: Yel/Blk, Red
Pnk/Blu, Blk sounds like the IAB connector on a GS-R.
The IAT and ECT share the same 'output'. So let the car sit overnight and measure the resistance of both the ECT and IAT - they should be relatively close in value.

I dont have the red/yel, green/wht on my cars for any of those - seems like the person I bought the car from must have changed the harness

in that case make sure you didn't damage the ECU. It will not have a CEL but your EVAP purge will never work and your IAT may be damaged.

Im pretty sure that the ECU isnt damaged. Ive tested the signals coming from the wire on the ECU to the Evap purge and IAT and both are showing some positive signals.
But I need to wait for the car to cool down and measure the resistance of both

Measured both the ECT and IAT plugs when cold
