Possible causes for a OBD II Diagnostic Trouble Code, P-1450, for a 2003 Ford Focus 2.3L?

Question

My son has a 2003 ford focus, 2.3L, and it is coming up with a DTC P-1450.  What are the possible causes, as well as different parts that could be tested, and how do you test them?  Also, what parts would you recommend changing out, and in what order?  Thank you for your help.

Answer 1

P1450 Unable to bleed up fuel tank vacuum

When this code set what happens is the ECM monitor the  fuel tank vapor and pressure, from the FTP (Fuel tank pressure) sensor, in most case the fault is usually traced to a faulty FTP sensor, If there is another component that is causing P1450 you would also set a drivabilty issue.
