Where is the canister purge valve located in a 2006 saturn ion?

SOURCE: 2006 saturn ion 2.2L engine code came up for EVAP purge/vent

replace your pvc vavle then have your cars underbody washed

SOURCE: got a code for the EVAP purge.vent solenoid circuit on 2006 ION

The dirt road might have a little to do with it, but it's just a typical sensor that goes bad in the emmission system.

SOURCE: P0496 I HAVE CHANGED GAS CAP. ONLY PROBLEM IS

check fuel pressure relief valve

Check engine P codes. GM uses an EVAP solenoid that is located under most vehicles near the gas tank and connects to the charcoal filter can. Codes can be set and will drive you crazy trying to figure out if you have a bad gas cap, broke lines---this is where they try to get you to do a smoke test, or you just think the vehicle is no good.

Relax, it is usually an easy fix and one GM has known about for years but continues to make easy money off people who cannot do basic maintenance. Now one code that comes up is usually P0449, along with maybe a warning to check the gas cap to see if it is on tight. Chevrolet will gladly read this code out for you for around $98.00 and then fix it for another around $100.00 which includes the EVAP part which if you buy at their parts dept. will cost you $32.00 and my dealership parts man told me they sell one a day! It is easy money for them and obviously a defective part they keep using for the last 10 or 15 years but hey, its money in their pocket. Here is how to fix it with ONE single common screwdriver!

Get under the vehicle after putting on the parking brake and if you a little hefty, then removing the spare tire on the some vehicles will give you lots more room. The EVAP solenoid is easy to spot near the gas tank and it has one electric connector which disconnects by releasing the plastic clip and pulling the connector out. It also has ONE air line connected which goes to the charcoal cannister which also can be removed with the one screwdriver. The whole EVAP solenoid and air can can be removed with the screwdriver which makes it easier to unpolug the electric and air line. Get a replacement from the dealer as they certainly are familar with this part as they sell LOTS of them. Then just go under and plug the new one in and the problem is solved. Now if you do not have a tool to reset the codes, try the local parts places as most of them will do a reset for you. If you do not have someone to do it, it can be done simply be removing the RED, positive lead off the battery and wait a minute and then plug it back in. The codes are reset but of course now you have to reset the radio and clock stuff.

Hope helps (remember to rate this answer).

SOURCE: I was told by a

The purge solenoid valvend canister are part of the EVAP system. The automatic diagnostic method tests the integrity of the EVAP system for leaks by pressurizing everything and then checking to see if pressure is lost. The filler cap is the main seal to the gas tank and if this is loose then compromises the ability of the system to be pressurized. Put a film of grease around the rubber seal and fit the cap tightly.

The following is a brief overview of the system (any spelling anomalies are due to my British background). I hope you find it helpful :-

What is it? The EVAP system is a collection of pipes and devices designed to prevent fuel vapour emission to protect the environment.

Where is it located? Pipes run from the top of the fuel tank to the carbon (vapour trap) canister which can be located between the inner and outer fenders (wings), on the inner fender or on the firewall (bulkhead). A pipe connects the canister to the throttle: the pipe exits just in front of the throttle plate.

How does it work? The EVAP system passively stores the vapour from the fuel tank in a charcoal filled canister. When the engine is running above idle speed the ECU opens a purge valve to the pipe leading to the throttle body. A vent valve allows the ingress of air into the canister and this encourages fuel vapour to be drawn out through the purge valve to be added to the air intake mixture to be burnt. The opening of the purge valve cycles with engine speed. The purge valve should be closed during idle.

Symptoms of faulty EVAP

• Erratic idling - If the purge valve fails to close the ingress of unmetered air will compromise the ECU's ability to maintain a suitable air/fuel ratio.

How to check? Simply clamping off the pipe from the EVAP purge valve should result in an immediate improvement in engine idling performance. Remove the purge valve and try to blow through it. If there is resistance then the valve is mechanically OK. Applying voltage to the electrical connections should open the valve and remove any resistance to blowing.

How to fix? If the valve is jammed open permanently or fails to open when signaled to do so then replace it. It may be possible, taking the greatest of care in the process, to open the valve to clean it up in the hopes of affecting a repair. If the solenoid itself, however, shows 'open-circuit' due to an electrical break it is best to replace it.
