SOURCE: car codes

When you have P0440, P0441 and P0446, it is a very good bet that the fuel cap was loose, or the fuel cap rubber seal is compromised. You will get all three of those codes every time that the cap is loose. Always make sure that the fuel cap is as tight as you can get it after you refuel.

These codes are all for the Evaporative Emissions System.

P0440- Evaporative emissions system fault- just saying there's something wrong with the system.

P0441- Evaporative emissions system- Incorrect purge flow- saying that the system isn't purging the raw fuel vapors (hydrocarbons- HC) as well as it should.

P0446- Evaporative emissions system- Control valve circuit low- there is a valve, usually located on the charcoal canister at the rear of the vehicle, that opens to allow fresh air to enter the evaporative emissions system as the engine vacuum purges the fuel vapors from the charcoal canister and closes when purge is not needed to prevent leakage of those fuel vapors to the atmosphere (HC is a greenhouse gas and is regulated as such by the fed gov't).

Given that you have the incorrect purge flow code and the control valve code together, my bet is that the vent control valve has failed (causing the P0446) and is not opening to allow fresh air into the system to displace the air from within the system that is being pulled to the engine. Since you have no fresh air entering the system, the engine will pull a vacuum on the system instead of the vapors "flowing" into the engine (causing the P0441).


I hope that this is helpful to you!!!

There fault codes are indicating a fault with your EGR system / EGR valve.

I believe those cades are for the transmission. Call the dealership and verify but I am almost positive those are transmission fault codes.

Hello there,my 2001 echo is lighting up trouble codes p0440 p0441 p0446; how and where should i start?


code p0440 refers to evaporative emission (EVAP) system--malfunction=== causes --hose connections --intake leak--EVAP canister purge valve
code po441 refers to EVAP --incorrect flow detected==causes the same as for po440
code po446 refers to EVAP system vent control --circuit malfunction===causes --wiring---EVAP can purge valve--ECM
generally I would replace the purge valve as it is common to all codes

I have a 1997 infiniti i30 with engine codes p0600,p0440,p0446,p0720, im trying to find out what the parts are for each code and where the part is located on the vehicle.


this is an obd2 trouble code table, it can help you understand the meaning of code.

for the p0440, you can try this:
Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
Inspect the EVAP system for cuts/holes in tubes/hoses
Inspect for damaged or disconnected hoses around the Evap purge solenoid
Check and/or replace the sensor
Check and/or replace the purge valve
Have a professional use a smoke machine to detect leaks

for p0446, you can try this:
Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
Inspect the EVAP system for cuts/holes in tubes/hoses
Inspect for damaged or disconnected hoses around the Evap purge solenoid
Check and/or replace the sensor
Check and/or replace the purge valve

HAVE A CODE PO446 1999 LEXUS GS300 CHECK GAS CAP AND IT WAS OK. WHAT DO I LOOK FOR NEXT AND LOCATION OF IT


P0446 is an evap code. Most likely, you need to change the charcoal canister vent valve (CCV) under the trunk floor. Fuel cap codes set 3 codes at once, P0440. P0441 and P0446, all at the same time.
