Looks like your check engine light is on? Find out why.

 

I posted a thread on here a while back, and i uploaded a video of me checking the codes, and the codes i got 1, 10, and 14
This is when i had a stock P07 ecu
I now have a p28 ecu
code 1- Heated oxygen sensor A
code 10 - Intake air temperature sensor
code 14 - Idle air control valve or bad ECM

I was thinking since i've changed the ecu, the codes would be the same.

 

Check the codes again. You may have the IAT plug swapped with the IACV. The two wire plugs are all the same. You need to check the wire colors to be sure they are plugged in the right place. (Do NOT just try swapping them, that can cause damage).

 

I'll take pictures when I get back to my car at 3:30PM EST and I'll post them to make sure I got them connected right.

But if i need the intake air sensor, this is what i'll need right?

 

 

The IAT is shown in the pictures???
the IAT is the one on the far right of the intake manifold right? shown in picture #3?
in picture #1 & #2 what sensor is that to the left of the IACV?

 

The black thing with vacuum hoses on it is the purge solenoid-- and it's not plugged in.
I think the IAT is directly underneath it, and it is white.

You have at least 4 two wire plugs back there to consider:
IAT -- Green+white & red+yellow
IACV -- blue+yellow & yellow+black
Purge -- yellow+black & red
Power steering pressure (if equipped) -- brown+red & black

 

I posted them hoping someone show a helping hand and point me in the right direction . my bad if i posted the wrong pictures.
Which connector is the IAT

 

Thanks

 

Colors of all the wires are in this sticky

Guessing it's the one under the purge one

 

Okay the IACV, the wire going in to the connector was solid red wire with yellow wire/black stripe


IAT colors were red wire with yellow stripe & green wire with white stripe

 

Of course the one with a yellow+black & solid red belongs on the purge solenoid.

Do you have everything plugged in properly now? Does it run any different?

 

I didn't change anything. i just looked at the connectors. I'll post pictures. Give me a second.

 

this is the connector in the IAT. (Intake Air Tempture Sensor)

 

So now you can cross iat off. Go plug in the others and report back.
