Which is faulty parts or malfunctions can cause trouble code p0446?
The letter P indicates a generic powertrain code, while the number 0446 points more specifically toward a malfunctioning vent control circuit in the evaporative emission control system. Which Faulty Parts or Malfunctions Can Cause Trouble Code P0446?
What to do if your fuel pressure code is p0456?
Scan your vehicle to verify P0456 is the only code present. If other codes are present regarding fuel pressure or the fuel system, repair and diagnose those first. If it is paired with P0441, P0440, and/or P0446, there is most likely a solenoid failure, leaking charcoal canister, or a more complex EVAP leak.
Where is the solenoid valve on a p0446?
P0446 Meaning. The Evaporative System (EVAP) canister vent control valve is located on the EVAP canister and is used to seal the canister vent. This solenoid valve responds to signals from the Engine Control Module (ECM).
When to repair a check engine light p0446?
The driver will likely not notice any symptoms associated with P0446 other than the check engine light being on. However, as with all check engine light diagnostic trouble codes, you should repair it as soon as possible to return the vehicle to normal operation. Scan your vehicle to verify P0446 is the only code present.

What does p0446 do to the EVAP system?
During the leak test, the ECM closes the vent control valve to create a sealed EVAP system. When P0446 is triggered, the ECM has detected a short in the circuitry to activate the vent control valve, or the EVAP system failed to maintain the proper pressure during the active EVAP leak test. What Are The Symptoms Of P0446?

However, as with all check engine light diagnostic trouble codes, you should repair it as soon as possible to return the vehicle to normal operation. Scan your vehicle to verify P0446 is the only code present.
Why does p0446 cause fuel tank to crack?
Building their nests in the vent line blocks the flow, some of them so bad that they cause EVAP DTCs to be set, including P0446, and some so bad that they’ve caused canisters and fuel tanks to crack.
