P22D5Turbocharger Turbine Inlet Valve Position Sensor Circuit Range/Performance

P22D5 indicates that the powertrain control module (PCM) has detected an out-of-range or performance fault in the circuit of the turbocharger turbine inlet valve position sensor. This sensor reports the physical position of the valve that controls exhaust gas flow to the turbine, and the PCM uses that signal to manage boost pressure and protect the turbocharger. The code means the sensor's voltage or rationality check has failed, not necessarily that the valve itself is stuck.
