What hoses do I check for check engine light code Po455


DTC P0455 Evaporative Emissions (EVAP) System Large Leak
The control module tests the evaporative emission (EVAP) system for a large leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the EVAP system vacuum level. When the conditions for running are met, the control module commands the EVAP canister purge solenoid valve OPEN and the EVAP canister vent solenoid valve CLOSED . This allows engine vacuum to enter the EVAP system. At a calibrated time, or vacuum level, the control module commands the EVAP canister purge solenoid valve closed, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum level. If the system is unable to achieve the calibrated vacuum level, or the vacuum level decreases too rapidly, this DTC sets.
There's more to it that just checking a hose ! Smoke testing the EVAP system is the best way to find leaks .
  1. Inspect the Evaporative Emission (EVAP) System for the following conditions:
  2. ?€¢
    A loose, missing, or damaged service port schrader valve


    ?€¢
    A loose, incorrect, missing, or damaged fuel fill cap


    ?€¢
    A damaged EVAP canister purge solenoid valve

  3. Raise the vehicle on a hoist. Refer to Lifting and Jacking the Vehicle in General Information.
  4. Inspect the EVAP system for the following conditions:
?€¢
Any disconnected, improperly routed, kinked, or damaged EVAP pipes and hoses


?€¢
A damaged EVAP canister vent solenoid valve or EVAP canister

Your best bet is take your vehicle to a ASE certified repair shop or the dealer , where they have the tools an knowledge .

P0455 is Evaporative Emissions System Leak Detected (Large) and means that there is a large leak in the system probably with one of the EVAP hoses near the fuel tank or EVAP canister or maybe even A leaky purge valve.

2000 Ford Focus...DTC code PO455


code PO455
EVAP Control System Large Leak Detected
Possible Causes:


Aftermarket EVAP hardware non-conforming to specifications Canister vent (CV) solenoid stuck open EVAP canister purge valve stuck closed, or canister damaged EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube disconnected or cracked, or canister is damaged Fuel filler cap missing, loose (not tightened) or the wrong part Loose fuel vapor hose/tube connections to EVAP components Purge sensor or FTP sensor is out of calibration or has failed I would say that your gas cap is a good place to start.

Engine dies while driving 55-65 mph


I guess the easiest thing would be replace your gas cap, or at least remove it and clean all threaded parts & seal if you haven't already. Erase codes drive it, then re-check.Next check all hoses etc., going to your vapor canister for leak, and canister for any holes.
