I have a 2013 f250 deleted with mini Maxx canned tunes that I installed a new factory garret turbo on last month. It has been running great all the way up until this week. Started getting a p132a code and building no more than 15 psi of boost and have tried erasing the code and it will just come right back up as soon as the key is turned on. Have replaced the wastegate solenoid pigtail due to the fact that it was brittle. Also pulled out the wastegate actuator solenoid and found a fair bit of buildup on the mesh screen that is on it but I cleaned it off before reinstalling. I checked the voltage running to the two wires on the pigtail and found that both have 12 volts KOEO. Any suggestions on where to go from here?

P132a is the same thing just for the Pulse Wave modulation. so my best guess would be the MAP sensor.

Thanks for the info I tried cleaning the sensor with no success. It was completely covered in oily soot. Have a new one on the way we will see if it fixes it.

Got around to installing new map sensor today, still no dice.

Too good to be that ez. Gotta be something in that line of troubleshooting.

Man I hope you have better luck with that code than I did. Spent a total of 6 months in the shop chasing that one. Checked all the sensors you already mentioned, new BCM, new ECM, replaced 2 sections of wire harness. Still no clue if it was actually fixed. Picked it up from the shop the last time, drove it straight to a dealership and traded it in.
It was a 2016 tuned/deleted with 86k on it.

here is a thread with the same issue Help. P132a turbocharger boost control A circuit
sadly.. looks like it might be a wiring issue. a few suggestions are given.
keep me posted. very interested.

No luck as of yet. I replaced the wastegate solenoid with the old one to see if that helped but no change. Also checked the wiring harness from solenoid all the way to ecm and found no issues. Anybody have a clue about how to check the ecm to see if it is bad?

Hey folks, JUST solved this issue. Customer brought in a 2017 F-250 bone stock. Dropped P132A went into limp mode. Checked the wiring and found no issues. Removed the MAP and it was choked with that greasy soot. Cleaned it, didn't work. Said screw it, and removed the upper intake and the lower one as well. The entire thing as clogged. What happened was that when I ran the truck there was a layer of soot blocking the MAP sensor. The boost would compact the soot again and the codes would drop. Cleaned it out. Purple power worked the best. Rinsed with water. Put everything back together. Erased DTCS and ran the truck for a while. Codes didn't return. HOPEFULLY this helps you guys out too. Also, this cleaning procedure works for that troublesome MAF/MAP correlation code and more than a few EGR codes if you're willing to disassemble the EGR cooler.
