P1445 INFINITI: NISSAN: EVAP CANISTER PURGE VOLUME CONTROL VALVE
The EVAP System (Evaporative Emission Control System) stores the vapors resulting from the combustion process in a certain container. In this way, the vapors are not expelled into the environment. As a result, less damage is caused to the environment. Therefore, the system uses switches, valves, and sensors, which are controlled by the ECM (Engine Control Module).
The opening of the bypass steam passage in the solenoid that controls the purge volume of the EVAP canister has constant variations to control the flow. The purge volume control solenoid repeats the On/Off operation, taking into account the signal provided by the ECM. This opening changes to suit the optimum engine control, which is determined taking into account the engine conditions. During the engine operation, the flow of fuel vapor from the EVAP canister is controlled while the airflow also changes.
OBDII fault code P1445 is set when the Engine Control Module detects the wrong operation of the EVAP canister purge volume control solenoid valve.
Diagnostic code P1445 OBD2 because of these reasons :
