I have 16 2500 53,000 miles I can clear these codes and they go away overnight but when she warms up she trips the engine light. Again . How can see if it’s turbo sensor or modular? Thanks guys

What kind of scan tool are you using, to me it does not compute !

The ( P Code ), stands for powertrain (engine and transmission) systems and associated drivetrain accessories.

Network & Vehicle Integration (U-codes) category covers functions that are shared among computers and systems on the vehicle

Chassis (C-codes) category covers functions that are, generally, outside of the passenger compartment. These functions typically include mechanical systems such as brakes, steering and suspension.

Body (B-codes) category covers functions that are, generally, inside of the passenger compartment. These functions provide the driver with assistance, comfort, convenience, and safety.

I looked a little deeper

P00AF: Code Meaning, Causes, Symptoms, & Tech Notes​

Engine-Codes.com
https://www.engine-codes.com › p00AF


Faulty Electronic Turbo actuator · Electronic Turbo actuator harness is open or shorted · Electronic Turbo actuator circuit poor electrical connection.
.........................................

Code P00A3 is set when the PCM detects a high charge air cooler temperature sensor signal. This usually indicates an open circuit. Bank 2 indicates the problem is with the second bank of the engine. That is, the bank that does not include cylinder #1.

U010C Code: Lost Communication With Turbocharger / Supercharger Control Module “A”​

Diagnostic trouble code (DTC) U010C indicates “Lost Communication With Turbocharger/Supercharger Control.” This code is set when the PCM loses communication with the turbocharger/supercharger control module or smart actuator.

The variable geometry turbocharger (VGT) is a forced induction device in many recently manufactured vehicles. Its sliding nozzle can adjust both the power produced by the turbine and the amount of air the engine gets. It ensures the turbine produces enough power to drive the compressor at the intended boost level, no matter the mode the engine runs on.

I hope that this helps some what
