Something is wrong with the Evaporative Emission controls or canister.--- Evaporative Emission Canister To prevent gasoline vapors from being vented into the atmosphere, an evaporative emission system is utilized to capture the vapors and store them in a charcoal filled canister.
---
Evaporative Emission Controls OPERATION Canister Purging Purging the carbon canister removes the fuel vapor stored in the carbon. With an EEC-IV controlled EVAP system, the flow of vapors from the canister to the engine is controlled by a Canister Purge solenoid (CANP) or vacuum controlled purge valve. Purging occurs when the engine is at operating temperature and off idle. Fig. 1: Canister venting system - 2.3L engine fuel evap won`t pass smog. - 86704009.gif
Fig. 2: Canister venting system - 3.0L engine 86704010.gif
Fuel Tank Venting Trapped fuel vapors inside the sealed fuel tank are vented through a vapor valve assembly in the top of the fuel tank. These vapors leave the valve assembly through a single vapor line and continue to the canister, for storage, until such time as they are purged to the engine for burning. Carburetor Venting In carburetor equipped vehicles, trapped fuel, which might otherwise pass directly into the atmosphere, is collected in the carburetor fuel bowl. These vapors are vented to the carbon canister when the engine is stopped through the combined efforts of the canister purge valve and solenoid, as well as the carburetor fuel bowl solenoid and thermal vent valves. When the engine is started and normal operating engine temperature is reached, the vapors will be drawn into the engine for burning. next.gif

Fortunately, this problem is limited in possible issues. Look at correct and functioning, and tight fuel cap, which is most common issue. There are vent tubes, vapor seperators, charcoal canisters, and purge systems, but they all are pretty rugged and rarely fail...Usually the test centers pressureize the cap and the fuel tank. You really need to know which one failed.

Some test centers only read the computer data, but that should have invoked the indication light, and then you would certainly fail...if you have a check engine light, pull the codes and fix that indication.

Could be lots of things.
It could have a leaky injector that is dripping all the time.
You can pull the injectors while still on the fuel lines, to see.
You could have bad compression and burning oil.
You need to do a compression test to tell.
You could have a bad plug or wire.
They are cheap to so just change them.
The fuel injection system could be off.
Check the temp sensor, air mass sensor, O2 sensor, with an ohmmeter.
Don't remember the values, but bad ones usually go 0 or infinite.

Hello and welcome to FixYa!
Here's a trick that always works. Get a hose and a powdered detergent. Soak the soap in the water and put it in the exhaust till it flows out. After that spray the tail pipe with water till the carbon goes out. This will clean the exhaust system and you will surely pass the smog test.
Hope this helps and thank you for using FixYa! Have a good one!

Had both air fuel sensors replaced to pass CA smog. OBD2 evap and catalyst monitors say "inc" or "not ready," and vehicle won't pass smog.


Not sure how old the vehicle is, or model, or engine, so I can only give general suggestions. You may need new catyitic converters, or O2 sensors. They sometimes can't be corrected, just replaced.
