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.

    Code says evaporator purge solenoid


    Which code specifically? Do not assume you need a new solenoid. Our recommendation will depend on the specific code and some troubleshooting results. I usually recommend checking over all the EVAP vacuum lines and the gas cap too whenever there is a purge valve code. Check the vacuum lines at the cannister in the left rear bumper. I will paste info on the purge solenoid below.

    Evaporative Emission Purge Solenoid

    Description & Operation
    The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
    During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.
    The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.
    Removal & Installation
    The duty cycle evaporative (EVAP) canister purge solenoid is located in the engine compartment near the brake master cylinder.

    1. Disconnect electrical connector at solenoid.
    2. Disconnect vacuum lines at solenoid.
    3. Lift solenoid slot from mounting bracket for Removal & Installation.

    To Install:
    1. Position solenoid slot to mounting bracket.
    2. Connect vacuum lines to solenoid. Be sure vacuum lines are firmly connected and not leaking or damaged. If leaking, a Diagnostic Trouble Code (DTC) may be set with certain emission packages.
    3. Connect electrical connector to solenoid.

    Po446 evap vent code where is the evap vent located


    Some might have an ses p0446, evap emissions vent circuit low. If you take it to the dealer they want 300-400.00 to fix the problem. GM has a service bulletin on this condition and have the updated part for 180.00, thats suppose to eliminate this issue.

    Basically the problem is, the evap purge vent valve gets clogged with dirt, especially if the truck is used in dirty conditions. Well I figured there had to be a cheaper way to cure this problem.

    Here it is:
    1) find the location of the vent valve; its under the truck, locate the charcoal canister on the front of the gas tank and trace the vent line to the vent valve.
    2) Take the bracket loose with a 5/8 wrench.
    3) Spin the valve around so the side with the hole is facing you.
    4) Take an air compressor and blow the vent valve out.
    5) reinstall and clear the code and it's fixed.

    Now I know the updated part from gm is supposed to keep the valve from clogging ever again, but why spend the money when all you have to do is blow out the vent valve every 50k-100kmi and save your $$$!

    Condition
    Some customers whose vehicles are operated in dusty type environments, such as farming or mining off-road type applications, may comment about the illumination of the instrument panel SES light, with a DTC of P0446 (Restricted/Blocked EVAP Vent Path) being set.

    Cause
    Dirt and dust intrusion into the EVAP canister vent hose assembly, resulting in restricted air flow, may cause this condition.
