My 2004 Mazda 3 GT 2.3L is getting a P0446 DTC and is burning through a tank of gas in about 2-3 days depending on the amount of driving being done. My Mazda dealer believes that it may be the fuel pump,...

P0446- Evaporative Emissions Control System Vent Control Circuit Malfunction

Possible Causes:
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

Code is detected when VSV for pressure switching valve is ON, ECM judges that there is no continuity between vapor pressure sensor, fuel tank and charcoal canister (2 trip detection logic)

The vapor pressure sensor, Voltage Solenoide Valve (VSV) for EVAP, Voltage Solenoide Valve (VSV) for canister closed valve (CCV) and Valve Solenoide Valve (VSV) for pressure switching valve are used to detect abnormalities in the evaporative emission control system.

The ECM decides whether there is an abnormality in the evaporative emission control system based on the vapor pressure sensor signal.

Diagnostic Trouble Code (DTC) P0446 is recorded by the ECM when there is a malfunction in either the VSV for EVAP, the VSV for pressure switching valve, or in the vapor pressure sensor itself, or when evaporative emissions leak from the components within the dotted line in Fig. 1 below.
The ECM closes the CCV and opens the VSV for pressure switching valve causing vacuum to increase in the entire EVAP system.

The ECM continues to operate the VSV for EVAP until the vacuum is increased to a specified point at which time the ECM closes the VSV for EVAP.

If the vacuum did not increase, or if the vacuum increased beyond the specified limit, the ECM judges the VSV for EVAP and related components to be faulty.

Check engine light ...code came up p0455 i have a 06 mazda 3 2.3

This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Symptoms: You likely won't notice any drivability problems.

Causes: A code p0455 most likely means one or more of the following has happened:
* A loose or improperly affixed gas cap
* A non-conforming gas cap (i.e. not factory/original brand)
* Other leak or damaged piece in EVAP system

Possible Solutions: With a p0455, the most common repair is to:
* Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, and/or
* Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

Hope this helps (remember to rate thsi answer).

What is a purge valve on a 2000 mazda xl and where is it located?

When the car is off, gasoline vapors from the fuel tank are absorbed in a charcoal cannister. When the engine is running, vacuum from the intake is directed to the cannister through the purge valve to **** the fumes from the charcoal back into your engine. This keeps the fumes out of the atmosphere. The purge valve is a solenoid controlled by the ECU to open when it thinks the engine can take the extra air. There is a little pump that sucks on the system to check for leaks and it sets a CEL if there is one.

The purge valve is part of the EVAP emissions control. This is a common failure in Mazdas.

Hope helped.
