I find that most of the time when the Evap system is not working its the purge valve/soliniod. if you are good with a multi meter you can test this to see if it has resistance through it if there is resistance or if it is bleeding to ground then you need to change out the soliniod. looks like this...

The EVAPORATIVE EMISSIONS SYSTEM on this car is more than one part, there are about a dozen components, if u have a leak you must have a shop do a system leak test, you don't mention any fault code, is it a fault code that lead you to ask this question? if so what is that code?

Hi! You may need to replace the evap system for it may be faulty. Usually it has 2 hoses that attaches to it and a bolt. Its not that painful to replace. Hope this helps and have a good one!

If you mean the evap for the A/C the first thing to check is the freon charge and check the system for leaks using a dye with flashlight setup.

Evap code cleared not ready showing


The EVAP monitor is a pain to set. It needs 2 full drive cycles and will not reset sometimes if an EVAP code is pending. Check the pending codes with your code tool and see if there are any for the EVAP, if not, like I said, the EVAP is a tough monitor to set.



How many other monitors are not ready?

Where is my evap located on a 1998 pontiac grand prix


which part of the evap system are you looking for. there are several components in your evap system. if you are looking for the evap canister it is located near the rear of the vehicle either on drivers side near the gas tank or just in front of the gas tank. it is a black plastic box with usually 2 vacuum lines running into it. if you are going off an evap leak engine code start with a new gas cap. a bad seal on a gas cap can cause the computer to read an evap leak. if that doesnt work then you may need to have a smoke test done at a local garage. basically they fill the evap system with smoke with a special machine then look for the smoke to appear from the leak in the system. again the evap system consists of several components that run from the engine to the gas tank. it circulates the vapor fumes from the gas back to the tank to be reburned so it does not get released into the atmosphere.

Engine code po442


I doubt code 442 would affect the performance of the engine. Code 442 is for a small leak in the EVAP system. The computer vents the gas tank to the vapor canister when the engine is running. The computer has detected a small leak in the venting system, usually a faulty gas cap or leaking vent hose.

Code p0452 on 2001 grand am 3.4 lit


P0452 The definition is evap pressure system low. This mean it detected a no pressure but rather a leak, There is nothing wrong with the pressure sensor or wiring itself,Fist thing to check is the gas cap,make sure the seals is good shape, The hose connection are firm and clamped down,you basically have a evap leak

Check engine light has been on for 2 years...have


The EVAP System has a leak and needs to be repaired.
Obviously your mechanic,has not kept up with todays vehicles. EVAP issues are common. I would get a new mechanic, and make sure they have an EVAP Smoke Machine,otherwise their wasting their time and yours.
Also,if your the type of person who rides around 2 years with a check light on,you don't have much interest in what you drive.
I would guess you got at least one other drivabilty issue.
Pull the codes,and have your NEW Mechanic repair properly and SOON

They did a smoke test and replaced the hose that was leaking code still popped up . po440 grand am


p0440 evap small leak detected. Should find with smoke machine. However, there could be a reflash for the computer to prevent this issue. Have the tech check for updated computer programs. If none are available you have a small leak in the fuel vapor system.

I have a 2001 grand am se p0440 code comes up


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.
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

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
