SOURCE: 02 monte carlo- EVAP code.

hi there, you see todays cars are so emmision friendly that not even the vapors from your tank can be released into the atmosphere so what they have done is all your vapors are put into a charcoal canister to absorb the vapors and the next time you start the car it has a purge solenoid open and burn the vapors off. if you look around the intake youll see a hose with a green cap follow it back to the charcoal canister and while your doing that just check the hoses and the hoses around the canister to make sure there is no holes or cracks in them and then follow the hose from the canister to the gas tank. if every thing looks good then i would replace the purge solenoid.

SOURCE: I have a purge valve or VMV fault code 1443 EVAP vaccuum system error

Without more information or testing its impossible to help diagnose this problem. However, when is the last time the oxygen sensor been replaced. My best guess in this situation and remember that this is not a easy item to replace as it is located within the exhaust system and is usually corroded.

SOURCE: check engine code "P0446 Evap Control System Vent Control Circ"

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

  • Faulty vent valve
  • Open, short or excessive resistance on Vent valve control circuit
  • Blockage of vent valve
  • Bad PCM
Here are some things you could try to fix it:
  • Replace Vent valve
  • Repair open, short, or resistance problem in control circuit
  • Repair open, or short, or resistance problem in power circuit
  • Replace PCM

I have a truck that popped up a P0443 code up and I've been trying to see what it is so I can get it fixed thank yo


P0443 - Evaporative Emission Control System Purge Control Valve Circuit Malfunction

Possible causes: - Faulty Evaporative Emission (EVAP) Purge Solenoid Control
- Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted
- Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection

When is the code detected? An improper voltage signal is sent to Engine Control Module (ECM) through the valve.
Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
P0443 Description: The Evaporative Emission System (EVAP) canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the Engine Control Module (ECM). The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.

P0443 CHRYSLER
P0443 DODGE
P0443 FORD
P0443 HONDA

Engine dies while driving. p0443 code. happens after I get gas.


P0443 Evaporative Control System Purge Control Valve Circuit Malfunction.

It is to do with venting the fuel tank.

It may simply be a loose gas cap.

I have a 2001 dodge ram 1500 code P0443 code came on code p0455 code was on I replace the purge valve then the code p0443 came on


code p0443=It's whining about the control circuit for the purge valve. Make sure you are getting power to the valve, and you see 12 volts on the control side as well.

code p0445 might be just a gas cap problem.

Code p0443


Code 443 is a problem with the EVAP canister purge control valve.
The computer can not purge the vapors in the gas tank to the canister because the valve is not functional.
The valve and the circuit would need to be tested.

P0449 and P0455 error code 2008 2wd gmc envoy 30,203 miles


P0449 - Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction

P0455 - Evaporative Emission Control System Leak Detected (no purge flow or large leak)

Both are refer at EVAP system; other EVAP DTCs: P0440 - P0441 - P0442 - P0443 - P0446 - P0453 - P0455 - P0456

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: 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: 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 helps.

It is coming up with p440 code


P0440 - Evaporative Emission Control System Malfunction

This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. 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 P0440 could mean one or more of the following has happened:
* The gas cap is not installed or working properly
* The purge solenoid has failed
* The canister is plugged and not working properly

Possible Solutions: With a P0440 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
* 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

Other EVAP DTCs: P0440 - P0441 - P0442 - P0443 - P0446 - P0453 - P0455 - P0456
