2001 Escort vacuum canister location - 2001 Ford Escort ZX2

this is sure to the EVAP system. do a visual check on all hoses and connections to start. If you can view live data on a scan tool you can see what the pressure sensor is reading. It should only have vacuum on it when the system is testing for leaks. It vents to the canister which is "purged" by the solenoid into the intake to be burned. It will throw a code if the system won't hold a vaccum, or has a vaccum when its not supposed to.

i think its on the fire wall with a vacuum line going to the intake look at the vacuum line for splits the line fails more than the sensor

This Pinpoint Test is intended to diagnose the following:

• Canister vent (CV) solenoid (9F945) (electrical concern only)
• Fuel filler cap (9030)
• Fuel tank pressure (FTP) sensor (9C052)
• EVAP canister tube (fuel tank to EVAP canister)(9A228)
• Fuel canister purge outlet tube (EVAP canister to EVAP canister purge valve) (9D661)
• EVAP return tube (EVAP canister purge valve to intake manifold) (9G271)
• EVAP canister purge valve (9C915)
• Vacuum source line (input port vacuum to intake manifold)
• Harness circuits: CV, FLI, FTP, EVAP Canister Purge Valve, SIG RTN, vehicle power (VPWR), reference voltage (VREF) and power ground (PWR GND)
• Powertrain control module (PCM) (12A650)

This Pinpoint Test is used as an assistance in diagnosing the following EVAP components:

• EVAP canister and bracket assembly (9E857)
  • EVAP canister sleeve assembly (fitting)(9D925)
  • Canister vent (CV) solenoid - hose assembly (9F976 or 9K318)
  • EVAP canister (9D653)
  • Canister vent (CV) solenoid (9F945)(mechanical concern only)
• Fill limit valve assembly (9A086)
• Fuel filler pipe flapper valve (9B085)
• Fuel filler pipe check valve (9189), assembly (9285)
• Fuel tank filler pipe (9034)
• Fuel tank assembly (with fuel vapor vent valve) (9K007)
• Fuel tank assembly (without fuel vapor vent valve) (9002)
• Fuel vapor control valve (9B190)
• Fuel vapor vent valve (9B593)
• Liquid/vapor fuel discriminator (9G332)
• On-board refueling vapor recovery (ORVR) T - connector assembly (9S314)

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.

The valve/solenoid is next to the battery--see picture below. here is the procedure from autozone.com. Let me know if you have questions.

Evaporative Emission (EVAP) Canister Purge Valve

1. Disconnect the negative battery cable.
2. Unplug the canister purge valve electrical connection.
3. Tag and disconnect the vacuum lines from the valve.
4. Remove the valve from the car.

To install:

1. Install the valve and connect the vacuum hose.
2. Attach the valve electrical connection.
3. Connect the negative battery cable.

The purge solenoid should be in the hard plastic vent lines that run under the tube between the intake and the air filter, ablove the transmission, it is common for vibration holes to be worn in the hard plastic tubes causing a vacuum leak. The purge solenoid is small and it has an electric wire coming from it. I 'think' your canister is in the front lower left corner under the hood, you may have to remove splash shields to see it. The problem is most likely in the hard plastic lines at the solenoid. Let me know if this helps.

Your IAC may be defective, first check the canister purge valve by removing the large hose off the charcoal canster and plugging the hose with a bolt or something you can fit into it, then try it also check PCV valve and see if it's bad. there are more things to check like fuel filter fuel pump and or fuel strainer if fuel tank but would need to have more information to help.

please explain in plain queens english as to what this valve is or what it does please ,never heard of this before,is it measuring the amount of evaporation of fuel in the inlet manifold?? the evaporation of the fuel in the tank ??

the vacuum canister is located under the battery tray on this model truck, however the most common problem are the vacuum lines that run around the battery box. usually the battry will leak acid at some point in time and create holes in the small hard plastic lines. i would remove the battery and check the vacuum lines first.

We found that one of the vacuum hoses had been cut, so we bought a connector for $3.00 and coupled them together, and it worked like a charm.
