SOURCE: code po449 States "Evaporative emission control

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).

    I have two codes come up when checking why my check engine light is on. P0447 and P0420. Any info on what these mean and what it takes to fix so I can pass my smog test??


    press the helpful button
    Definition of P0420 is catalyst below threshold. This is indicative of (among other things) a converter that is not working as efficiently as it should be (according to specs). Catalytic converters are not normally a "wear" type item, that is they are not deisgned to wear out and need replacement. If they have failed, it is likely due to something else that caused it to fail.

    P0447 Evaporative Emission Control System Vent Valve/Solenoid Circuit Open. The Powertrain Control Module (PCM) has detected an open within the circuit that controls the vent valve or solenoid for evaporative emission systems vapor.

    DTC P0496 - EVAPORATIVE EMISSION (EVAP) SYSTEM FLOW DURING NON-PURGE

    SYSTEM DESCRIPTION
    This DTC tests for undesired intake manifold vacuum flow to the evaporative emission (EVAP) system. The control module seals the EVAP system by commanding the EVAP canister purge valve Closed and the EVAP canister vent valve Closed. The control module monitors the fuel tank pressure (FTP) sensor to determine if a vacuum is being drawn on the EVAP system. If vacuum in the EVAP system is more than a predetermined value within a predetermined time, this DTC sets.

    2005 Suzuki Forenza, check engine light is on with fault codes reading P0488 and P0496. Can't get a good explanation of what the cause may be. Any insight would be greatly appreciated.


    code P0488 exhaust gas recirculation closed valve pintle error ( EGR Valve ) most likely replace the valve.

    code P0496 evaporative emission system continuous purge flow. could be many things, Gas cap, purge valve , purge canister, probably need to have this one check by the dealer.
