DTC codes / P25xx · Vehicle speed, idle control and auxiliary inputs / P25F3
P25F3 indicates that the powertrain control module has detected an out-of-range or erratic signal from the turbocharger or supercharger boost sensor C circuit, which is often a secondary or redundant boost pressure sensor. The computer compares this signal against expected values from other sensors and sets the code when the circuit's voltage or pressure reading falls outside the normal performance window for a calibrated period.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
