Based on the systems affected by this code, we will most likely start with:
P2625
WysokiInjector Control Pressure Regulator Circuit – High Signal. The PCM detected voltage in the ICP regulator circuit above the allowable range.
OBD-II (EN): Injector Pressure Control Regulator Circuit High
Code P2625 means the PCM detected too high voltage in the injector control pressure regulator (ICP) circuit. This could be caused by a faulty regulator, a wiring problem, or an engine controller fault. Due to the impact on the fuel system's operation, prompt diagnosis at a workshop is recommended.
Symptoms
Check Engine Light (MIL) on; rough engine idle; fluctuations and jerking during acceleration; noticeable loss of engine power; possible difficulty starting the vehicle.
Possible causes
Faulty or defective injector control pressure regulator (ICP Regulator) Short to supply voltage (+12V) in the regulator signal circuit Damaged wiring or corroded electrical connectors in the ICP circuit Incorrect signal from the powertrain control module (PCM/ECM) Faulty or outdated PCM software High resistance in the regulator return (ground) circuit
