02 Saturn SC1 = I replaced the purge valve solenoid, located above the starter. My service engine soon light still came back on. (I'd turned it off, but it reappeared) The same code still exists. The probable cause analysis states: Purge or vent solenoids defective; Check connector and wiring; Fuel saturated vapor canister; Failed EVAP vent solenoid. Has anybody run into this problem before? What is my best solution?

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: saturn code p0442, evap system small leak, can't find leak

i would check the plastic pipes which run from the canister to the fuel tank ,these are usually located behind the fuel tank

Testimonial: "found another defination for a code 422. replaced rear o2, problem fixed! "

SOURCE: what would cause my vue to lose power & die on the highway

that will not make your car to quit running. vue had problem with ignition module. it's easy to replace and it's right on top of the engine. a small, flat almost square silver box on the top of engine.

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).
