Look for vacuum leaks in the system going from the purge valve all the way back to the fuel tank.

2004 Honda Pilot Evap code P1456 Changed gas cap from honda and still


code p1456 refers to evaporative emission (EVAP) canister purge system(fuel tank system) -leak detected===causes--hose-fuel tank/pressure sensor--fuel filler cap--EVAP valve /bypass solenoid--EVAP two way valve---EVAP canister/vent valve

There is also a second reference to the code which is EVAP system leakage ====filler cap--EVAP canister purge valve--hoses---EVAP canister shut off valve---ECM programming---ECM

Check with the service dealer that the filler caps are interchangeable . It may be coincidence that the problem started after you changed caps or it may have shown a failure in the making

What is code p1443 on 96 thunderbird


PCV valve would have nothing to do with it !
P1443 - Very Small Or No Purge Flow Condition A fuel tank pressure change greater than a minus (-) 7 inches of H 2 O in 30 seconds has occurred with purge (fuel vapor) flow less than 0.02 pounds per minute.
  • Blocked fuel vapor hose between EVAP canister purge valve and FTP sensor.
  • Blocked fuel vapor hose between EVAP canister purge valve and engine intake manifold.
  • Blocked vacuum hose between EVAP canister purge valve-solenoid and engine intake manifold.
  • EVAP canister purge valve stuck closed (mechanically).
Check for blockages between the fuel tank, EVAP canister purge valve and engine intake manifold. Check obstructions in the EVAP canister purge valve diaphragm and ports.
Suggest you buy a repair manual if you want to try an fix yourself .Or Go to ford web site Ford Oem1stop com an pay 29 bucks for 72 hours for repair info . Or take it to a qualified repair shop an have it smoke tested . Or goolge purge valve for a pic. an see if you can find it under the hood .

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.

You must have a leak somewhere in the tank, because gas caps seal and vent at a certain pressure (1-2psi) a smoke test would check it. Try clearing the code first. If it keeps comming up, test it.

1996 Ford Aerostar 3.0 L V-6 Constant check engine light ON Ran codes. Code says vacuum leak on fuel canister. I'd like to change all the vacuum lines. Don't have a good schematic. Haynes manual only...


what codes?

The vacuum lines run from the canister to the intake manifold. One is the purge hose to deliver stored fuel vapor to the intake to be burnd when engine is warm and you are crusing at part throttle. The other line is the vacuum line to operate it.

Fuel Vapor Valve, Aerostar (4.0L Engine) The evaporative emission valve (9B593) uses a small orifice, 1.83mm (0.072 inch), that allows vapors to pass into the vapor line running forward to the evaporative emissions canister (EVAP canister) (9D653). This evaporative emission valve mounts directly into the fuel tank (9002) using a fuel vapor separator seal. Fuel vapors trapped in the sealed fuel tank are vented through the orificed evaporative emission valve. The vapors from the fuel tank leave the evaporative emission valve through a single vapor line and continue to the evaporative emissions canister in the engine compartment for storage.

Fuel Vapor Canister Purge Regulator Valve, Aerostar, Ranger Removal and Installation
  1. Disconnect wire harness from evaporative emission canister purge valve (EVAP canister purge valve) (9C915).
  1. Disconnect wire harness from thermistor.
  1. Disconnect evaporative emission canister purge valve assembly from fuel vapor canister and throttle body.
  1. To install, reverse removal procedure.

P1443 code How do I fix this code problem on my 97 Ford ranger?


P1443 is the Evaporative Emission Control System Control Valve. Any time you get this code always check your gas cap. If it is not installed all the way, or leaks, it can cause the evap emission code to come up. If the cap is okay...

The problem is probably caused by the Canister Purge Assembly. This assembly connects the intake manifold to the charcoal canister and the assembly is made up of hoses, a valve and a sensor. On the 1997 Ranger, it is located near the front of the engine compartment on the driver's side (the canister is right behind the driver's side headlight). Apparently, if there are any cracks in the hoses, or if the valve or the sensor wears out, this will cause the check engine light to come on, and return the P1443 code.

Part numbers for the canister purge solenoid/flow sensor assemblies:

F57Z-9C987-AB Canister Purge Solenoid/Flow Sensor
Assembly - 2.3L F57Z-9C987-CA Canister Purge Solenoid/Flow Sensor
Assembly - 3.0L F57Z-9C87-BA Canister Purge Solenoid/Flow Sensor
Assembly - 4.0L

Part cost = $65 to $100 depending on engine size - good luck :O)
