SOURCE: Getting an engine code 1450 on a 2003 ford

Did you check the block box connected to the vent solenoid? There's a hose that comes off it that appears to run nowhere, that's the fresh air vent. If it's blocked it won't allow air into the system which will set the trouble code. If that's clear, the vent solenoid itself is bad and needs to be replaced.

2000 Ford Expedition My Expedition (4.6L V-9 2WD) has had an intermittent problem of cutting out. The Check Engine light was not coming on - so I figured it is not a misfire. It drove just like it had...


Continuous Memory Diagnostic Trouble Code (DTC) P0446 or P1450 indicates that Self-Test has detected the Evaporative Emission Control System has excessive fuel tank vacuum. Also, a DTC P0446 indicates a vent control malfunction.

Possible causes:

EVAP canister purge outlet tube (EVAP canister purge valve to EVAP canister) blockages or kinks.

EVAP canister tube (fuel tank to EVAP canister) blockages or kinks.

Fuel vapor elbow on EVAP canister contaminated.

Restricted EVAP canister.

Canister vent (CV) solenoid stuck closed (partially or fully).

Plugged or contaminated CV solenoid filter.

EVAP canister purge valve stuck open.

Fuel filler cap stuck closed (no vacuum relief).

VREF circuit open in fuel tank pressure (FTP) sensor.

Damaged FTP sensor. (fuel tank pressure)

Check for kinks or bends in the fuel vapor hoses/tubes (EVAP canister purge outlet tube and EVAP canister tube).

Visually inspect EVAP canister inlet port, CV solenoid filter and canister vent hose assembly for contamination or debris.

Check CV solenoid filter for blockage or contamination.

The common things I've seen are are mud in the canister and the canister vent solenoid being shot or the wiring to the canister vent solenoid being torn off. The resistance of the solenoid should be 48-65 ohms..
Pick up a Chiltons book and will give you a diagram of where exactly you find the canister. They are like $15 at any auto store. Good luck

Check engine lite came on code is p1443 what does this code mean


P1443 Evaporative Emission Control System Control Valve The Evaporative Emission Control System monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM.

Code P1443 Possible Causes:

- Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister)

- Damaged EVAP canister

- Disconnected, cracked or cut fuel vapor tubes/hoses (except between fuel tank and EVAP canister)

- Damaged EVAP canister purge valve

Ford escort wagon 1997 code p1443 displayed. what does this indicate & where is the cannister? thank you.


P1443 - EVAP Control System / Vacuum System Purge Control Solenoid Or Purge Control Valve Fault. A fuel tank pressure change greater than minus (-) 7 inches of water in 30 seconds occurred with a purge (fuel vapor) flow at less than 0.02 pounds per minute.

Possible Causes:
  • Blocked fuel vapor hose between the EVAP canister purge valve and the FTP sensor.
  • Blocked fuel vapor hose between the EVAP canister purge valve and the engine intake manifold.
  • Blocked vacuum hose between the EVAP canister purge valve solenoid and the engine intake manifold.
  • EVAP canister purge valve stuck closed (mechanically).

  • Possible Solution:
    Check for blockages between the fuel tank, the EVAP canister purge valve, and the engine intake manifold. Check for obstructions in the EVAP canister purge valve diaphragm and ports.

    The canister is on the passengers side near the firewall if I recall correctly.

    Obd-2 code p1455


    DTC P1455 - Substantial Leak or Blockage in Evaporative Emission Control System

    The PCM monitors the complete EVAP control system for no purge flow, the presence of a large fuel vapor leak or multiple small fuel vapor leaks. The system failure occurs when no purge flow (attributed to fuel vapor blockages or restrictions), a large fuel vapor leak or multiple fuel vapor leaks are detected by the EVAP running loss monitor test with the engine running (but not at idle).

    Check this possible causes:
    After-market EVAP hardware (such as fuel filler cap) non-conforming to required specifications
    Disconnected or cracked fuel EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube
    EVAP canister purge valve stuck closed
    Damaged EVAP canister
    Damaged or missing fuel filler cap
    Insufficient fuel filler cap installation
    Loose fuel vapor hose/tube connections to EVAP system components
    Blockages or restrictions in fuel vapor hoses/tubes (items also listed under disconnections or cracks)
    Fuel vapor control valve tube assembly or fuel vapor vent valve assembly blocked
    Canister vent (CV) solenoid stuck open
    Mechanically inoperative fuel tank pressure (FTP) sensor


    Check for audible vacuum noise or significant fuel odor in the engine compartment or near the EVAP canister and fuel tank

    2000 ford taurus gas tank has what appears to be a fitting on the top right rear that has hoses attached. there are stains and gas smell coming from this area. my repair manual mentions a plastic push...


    The Evaporative Emission Control System monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM.

    Code P1443 Possible Causes:

    - Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister)

    - Damaged EVAP canister

    - Disconnected, cracked or cut fuel vapor tubes/hoses (except between fuel tank and EVAP canister)

    - Damaged EVAP canister purge valve

    Notes: Check for audible vacuum noise in the engine compartment or significant fuel odor in the engine compartment or near the EVAP canister.

    On my '98 4x4, the cannister purge valve is located under the hood, mounted on the driver's side fender.

    The EVAP cannister itself is located underneath the truck, in back, between the spare tire and the truck bed (have to remove the spare to get at it).

    If it were me I would hold off on replacing parts...I'd drive around some more first, making sure that I don't overfill the gas tank or run it dry and making sure I replace the gas cap properly, etc. If the code returns, then its time to think repairs.
