Trying to look up the code in Mitchell P0449 for a 2003 Mountaineer shows it to not be plausible. Is there a typo? Other cars can set that particular code and it would be a vent solenoid "circuit" issue. Which would be correctly tested by checking for power to the solenoid, and then using a scan tool bi-directional controls to prove that the computer can turn the solenoid on. The second diagnostic event "na 01/01" has to be a scanner issue. You may want to try a different tool.
I was there before, and know the code does not exist for the Ford line. When I stated that, I was told to google it, and there is information on the Ford line, so that's why I asked them to find this information so they could get an idea that the vent solenoid is not necessarily the fix.
Reset the computer,
ok I reset the code or erased it and after three starts the engine light reappears. check the gas cap seal is good
You people only see what you want to see and hear what you want to hear. You have your answer right below here. I don't know why I even care, you won't even listen. You deserve to have your light on. Good luck.
don't take It personal my friend explain to me a little more clearer and I will get it. Are you saying the see more on the web page.
If you want to know more. Follow the instructions for some ways to find it and you can read it for yourself without somebody tying all the information. It's all there for you. Good night.
What is the code now? On the left side of this post is a place to look things for some good information. Under encyclopedia you will find the 'exhaust & emission' labeled, and click on that for information about the EVAP system and the operation of the components. Just because it called for a vent valve, does not mean the vent valve is the problem, you have another problem that needs to be diagnosed. I f you will google p0449 Ford explorer, there is a listing for a RepairPal article on the complete understanding of this code and the proper way to consider the fault code. Good Luck.
