Yes I've been driving it and i rotated the sensors in the correct orientation while doing so my new plug n play harness still looks fine

 

Ok, the easy first thing to check, is remove the lower TMAP sensor and check if it is oil fouled. Clean it with MAF sensor cleaner.

If it's fouled, you may want to remove the lower charge pipe and clean it out. Then install catch cans in the PCV systems.

Before I installed the sensor in the new pipe I have it a healthy shot of MAF cleaner but I do wonder something before I changed the piped I didn't have a baro reading on my RPD and always had a code for it now that I have changed my pipes I now have a baro reading on my RPD and the baro code is gone. So correct me if I'm wrong but both issues stem from the lower Map correct and even the same wire? So I believe I'm back to chasing wiring since my IATs are holding a consistent +150° Temps for some reason

 

Maybe remove the dirt cheap plug and play adapter, and test it.

 

I've been reading this and want to know something.
You installed the ZZP pipe that relocates the lower TMAP sensor away from the AC compressor.
So now there should be no issues with the sensor or wiring.
But you do ?
It's been said the IAT sensor works hand in hand with this sensor but I don't see how.
The IAT sensor is in a different location.
Would like to see a wiring diagram to help explain this.
Yes I'm missing something completely here.

 

You and me both man I'm just at a complete loss.

 

I guess I haven't thought to grab a multimeter and see if I'm even getting signal through it, do you know off hand which wire is ground so I can complete the circuit on my tester

 

Here's something, thanks again, FMG.

 

thank you

 

The IAT sensor is part of the MAF sensor.
Presumably you disconnected the battery for the installation, that would clear codes. P2227 runs once while cranking, then constantly while running.
What IAT temp are you expecting?

I thought the BARO was part of the MAP. but evidently on the SS there is a port on the ECM that can collect dust and ice, cleaning that is the repair procedure in the Mitchell OnDemand book for P2227.
