    thanks for info. yes, codes did all set at same time. however, no PO600-610 codes present. so, can it really be PCM? heard PCM replace expensive and probably remanufactured.

The first code is for the secondary air injection system. It could be as simple as a fuse or broken wire. It could also be the air pump. The second is the purge solenoid control circuit. Again it could be a wire or the solenoid. The third is also a EVAP code related to the vent valve, and may also be the wiring or the valve. Did all these codes set at the same time? If so you may be looking at a PCM problem. It is really hard to venture a guess at the cost without lnowing more. I advise you to use a good shop that you trust. It will take some special equiptment to properly diagnose these issues. Good Luck

    It could be the PCM. The reman. PCM's should not be real high. I would see what the shop tells you is wrong first. Then before you give permission for the repair price the parts yourself from local parts stores. Understand most shops mark up the parts a little, but any more than 10% is too much. If it is the PCM it will have to be programed at a dealer and this usually costs a hour labor too. Good Luck

Your Po449 code means: Evaporative Emission (EVAP) Vent Solenoid Control Circuit. Check to see if anything on you EVAP system has gotten disconnected and make sure that none of your hoses have gotten old and bridle or have holes. If everything looks ok, you probably have to replaced the Vent Solenoid Valve, which is located on the EVAP canister.

The code P0449 indicates a problem with the vent sol.being either stuck on or off.
This is usually caused by road dirt getting into the vent sol. due to it's mounting location above the fuel tank.
You have options, one is just simply replace the vent sol. the other and the correct repair is to install a kit and a filter to the vent sol.
Dirt and dust intrusion into the EVAP canister vent hose assembly, resulting in restricted air flow, may cause about the illumination of the instrument panel SES light, with a DTC of P0446 (Restricted/Blocked EVAP Vent Path).
