Question about Infiniti Cars & Trucks
I have SES light on my infiniti FX35. P1446 evap vent control valve. Have checked valve itself is working, what can be the reason. actually checked all the parts, leack for evap system, no problem. exept boost sensor, is this can be the falt sourse? does boost sensor has a separate trouble code, DTC?
For your infiniti FX35,
P1446 - Infiniti Type Powertrain - Manufacturer Controlled DTC - Manufacturer Controlled Description Evaporative emission (EVAP) canister purge control valve - malfunction
Cause Wiring, EVAP valve, mechanical fault, ECM

SOURCE: GM Code 442
Do you mean code P0442? I would assume that's what you mean since you said it relates to the Evap System
This code indicates that there is a fuel vapor leak in the system. This means that a very small leak has been detected. The leak can be from a hole as small as 1mm
This code point towards any of the following:
a loose gas cap or a non factory spec gas cap
a small leak or hole in the fuel vapor hose/tube
faulty vent o-ring seal
The most common fixes is to re install the gas cap, clear the codes, and see if the code returns. Or replace the gas cap and clear the codes and see if it returns. Finally inspect the hoses/tubes for cuts/holes
This code in no way points to a canister requiring to be replaced.

Unfortunately, this code has nothing to do with the gas cap....
A code P0446 could mean one or more of the following has happened:

P0452 Evap.Emission System-Pressure Sensor Low Input
The evaporative emission control system prevents hydrocarbon vapors from escaping from the fuel tank into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The Fuel Tank Pressure Sensor (FTPS) is an integral part of the evaporative monitoring system. The PCM monitors the FTPS signal to detect vacuum decay and excess vacuum. The FTPS measures the difference between the air pressure inside the fuel tank and outside air pressure to check the purge control solenoid valve operation and for leak detection in the evaporative emission control system by monitoring pressure and vacuum levels in the fuel tank during the purge control solenoid valve operating cycles.

EVAP fuel tank pressure sensor low output. It sounds like the charcoal -filled canister, it's near the gas tank in a cylinder shape.The canister may have cracks or a hose is leaking around the area and it will give a fault code of PO452. Are you smelling any odors or emission smell from the car?

sorry but your code reader is not reading manufacturers codes ,if an american market vehicle then you should be able to read them but if this is a europeon model then how did you manage to get this code??
P0235....Turbo/Super Charger Boost Sensor 'A' Circuit
this is a generic code if its any help
