MAP Sensor Test Procedure 2014 Ecoboost
2014 F150 XLT Ecoboost.
I have P0172. I purchased a OBD2 diag wifi and got it all hooked up. I see 3 MAP sensors but only 1 readout for MAP on the OBD2.
I need to clean/test the MAP sensors. Can someone tell me what they are supposed to read (Hz or variable volts at the signal out/signal ground wires).
Any help is appreciated.

Cleaned all 3 MAP sensors. And changed plugs. Long term fuel trim is still -25% on bank 1. And bank 2 is very low also -10%-15%. Long term FT stays around zero when rpm’s increase. Short term fuel trim is near 0. So looks normal when rpms are up. LT fuel trim shows rich -25 at idle. Any other suggestions.
Where is the intake air temp sensor? And how do I actually test the MAP sensors? Also, emissions test report says O2 heater.

Yes, it's a little bit different on the 2011s though. For the 2012+ that part number with a -A is on the air cleaner, -B on the intercooler outlet tube and -- on the intake manifold. They are all a combination pressure and temp sensor.
