Testing diagnostic's associated for the codes is how to find the fix. Assuming as to a fix would only be a guess . Your best bet would be to take it to a qualified repair shop .OR you could look on youtube .

SOURCE: My 06 cobalt has these codes can anyone tell me what they mean? Are they an expensive fix? p0446,p0455, p0172

code p0446 refers to evaporative emission (EVAP) system-vent control-circuit malfunction===causes --wiring--EVAP canister purge valve--ECM
code p0455 refers to EVAP system-large leak detected===causes --hose connections--intake leak--EVAP canister---EVap canister purge valve
code p0172 refers to system too rich, bank 1===causes intake blocked---EVAP canister purge valve--fuel pressure ---EGR system---injector/s ---ECM
because the EVAP purge valve appears in all codes I would be inclined to change that unit first the run the fault codes again

How do I fix the code p0446 and u1153

Hi Betty , what kind of vehicle do you have ? your probably better off taking this to the shop ! P0446 Evaporative Emmission Control System Vent Control Circuit You could have a wiring problem or the vent solenoid is bad >

U1153 is a code that sets when one of the modules is not communicating , what it means is one of the modules is off line. I don't know how much you know about newer vehicles , There is a serial data communication network that the control modules use to share data . Most newer vehicles have 10 or more such modules , ecm- engine module , air bag , anti-theft , anti-lock brakes , some sort of a body control module , transmission, HVAC - heating , ventilation , air conditioning ! Newer cars use CAN- controller area network , GM - GMLAN , class 2 data bus ! You need a up scale scan tool to do this repair an possibly a oscilloscope !

How to fix code P0446 on chevy uplander 2006?

icon1.png Quick fix for code p0446 evap emissions vent circuit low.
As the title says: some might have an ses p0446, evap emissions vent circuit low. If you take it to the dealer they want 300-400.00 to fix the problem. GM has a service bulletin on this condition and have the updated part for 180.00, thats suppose to eliminate this issue.
Basically the problem is, the evap purge vent valve gets clogged with dirt, especially if the truck is used in dirty conditions. Well I figured there had to be a cheaper way to cure this problem.
Here it is:
1) find the location of the vent valve; its under the truck, locate the charcoal canister on the front of the gas tank and trace the vent line to the vent valve.
2) Take the bracket loose with a 5/8 wrench.
3) Spin the valve around so the side with the hole is facing you.
4) Take an air compressor and blow the vent valve out.
5) reinstall and clear the code and it's fixed.

Now I know the updated part from gm is supposed to keep the valve from clogging ever again, but why spend the money when all you have to do is blow out the vent valve every 50k-100kmi and save your $$$!

Po101 code

Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. Check for air leaks on or around any intake pipework using a good spraying of carb cleaner, if the engine surges then that's the leak. Check wiring to Maf and if the inside is dirty, again use carb cleaner liberally...NOTE: do not use Wd40... If the code comes back, it may be necessary to replaced the mass air flow sensor.

P1442 usually gas cap. P1449 usually vent solenoid. P1441 usually always a faulty FTP sensor. Very problematic to Malibu, Grand Am Cavaliers and Aleros. That would be my first area to check. They are also known for poor wiring connections at the Left rear passthru connector to the fuel tank and vent solenoid, but not necessarily for that code.

Got a code of p0446 on my 95 gmc jimmy 4wd. what is it and how do i fix it? When do i know it is solved? Or what should i look for?

P0446 - Restricted/Blocked EVAP Vent Path.

The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Possible Causes:
Dirt and dust intrusion into the EVAP canister vent hose assembly, resulting in restricted air flow, may cause this condition.

Possible Solutions:
- Clean the EVAP canister vent hose assembly.
- Replace the EVAP canister vent valve & solenoid.

The DTC will clear once the issue has been resolved or you can clear the code with a GM approved scanner. Do not clear the code before the issue is corrected otherwise the light will keep coming on.
