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

Anytime Iput gas in after 10-20 stop and starts it has extended cranks for 1 minute the turns over till the next time I put gas in . I only put in 3/4 tank so I don't over flow/ I have put in cran


Then the system is purging when it should not. when the system purges certain criteria needs to be met.Fuel vapor are forced to flow in the canister from the fill vent valve to the fuel liquid vapor seperator this isolates fule from vapor there the vapor goes to the canister the vapor from the canister is fed in to the intake manifold into the combustion chamber this according to the purge process. The solution is to monitor the purge control solenoid unless the cansitor is fuel soaked.

I have a 2004 Jeep Wrangler. The Engine light came on. I had Auto Zone check the code for me. I don't remember the number, but they said that it was the Purge Valve. I had to buy the Purge Valve from...


Could be the P0445 - Evaporative Emission Control System Purge Control Valve Circuit Shorted
The EVAP canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
- Damage harness or connectors to the Purge Control Valve
- The valve circuit is open or shorted
- EVAP canister purge volume control solenoid valve may be faulty

When is the code detected?
- An excessively high voltage signal is sent to ECM through the valve

Try to remember this code number for additional details. Hope this helps, keep us updated.

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.
