PO12D code showing on my 2013 4.5 ecoboost
Hello, I couldn't find this code in the DTC list.
It says "Turbocharger inlet pressure circuit high". I have never had a single problem with this truck in the 8 years I've owned it. Had a transmission program recall on it and regular service over the years.
It has been my favorite F150 over many years, and I've had some good ones.
Any help is appreciated and if it is a complex problem, I will take it to the shop but would like to have a little knowledge on the subject before I go.
Thanks again for any help.

There's a TSB on that:
2013 Ford F150 EcoBoost P012B / P012D Bulletin 14-0082
One known bulletin, for example, is Ford TSB 14-0082 which applies to 2013 Ford F-150 pickups with the 3.5L EcoBoost V6 engine. If you have a P012B and/or P012D code with that vehicle, here is a PDF copy of the full bulletin. The fix is to replace the sensor & connector with updated parts, wire part number BU2Z-14S411-ATA and sensor part number CV2Z-9F479-A. Summary below:
Some 2013 F-150 vehicles equipped with a 3.5L GTDI engines may exhibit a MIL illuminated with diagnostic trouble code (DTC) P012B (turbocharger/supercharger inlet pressure sensor circuit range/performance) and/or P012D (turbocharger/ supercharger inlet pressure sensor circuit high) stored in powertrain control module (PCM) memory.

Thanks for the PDF and the reply. Looks like I’ll have to replace the sensor and the connector. But for some reason, I recently ran into problems opening my saved PDFs, so I tried converting them with the online tool https://pdfguru.com/forms/w-9-form I usually use to fill out W-9 forms. By the way, it’s also very convenient for adding notes and editing PDFs, and honestly, it makes working with manuals much easier.
