P1450 Error Code

[rmanick1]

Please Help.

The “Service Engine Soon” light recently came on in my 2001 Ford Taurus SES with a 24 valve DOHC engine. I read the trouble codes which indicated a "P1450 malfunction" which I was able to identify as the “Inability of Evaporative Emission Control System to Bleed Fuel Tank”. I proceeded to replace the fuel filler cap, since it was the easiest thing to do, but that did not fix the problem.

I also checked for kinks in all the hoses and fuel lines in and around the EVAP canister which I believe is located in the rear underneath of the vehicle. However, I did not come across any indication of any problems.

I would really appreciate some help figuring out what the actual problem is along with advice as to how to proceed and troubleshoot the problem and a suggested potential fix. Any help would be greatly appreciated.

Thanks in advance.

Doesn't seem to be a common issue with an easy typical fix.

It sounds like you may already have this information, but typical causes for this code would be:

• Blockages or kinks in EVAP canister tube or EVAP canister purge outlet tube (between fuel tank, EVAP canister purge valve and EVAP canister)
• Fuel filler cap stuck closed (no vacuum relief)
• Contaminated fuel vapor elbow on EVAP canister
• Restricted EVAP canister
• CV solenoid stuck open (partially or fully)
• Plugged CV solenoid filter
• EVAP canister purge valve stuck open
• VREF circuit open (harness near FTP sensor, FTP sensor or PCM)
• Damaged FTP sensor
