was the CEL on and fuel cap light on before you had the fuel pump replaced? if it was after the repairs were performed, double check all evaporative emissions lines, hose, and connection on and around the fuel tank. also make the the fuel filler neck is properly seated and clamped to fuel tank. if all good, check the plastic fuel filler top (just behind fuel door, where you put fueling nozzle) make sure it is not chipped or cracked anywhere. especially where the rubber seal from the cap rides.

Hello,
Very common concern with the Explorer, Explorer Sport Trac and Ranger with the 4.0l SOHC engine! The upper and lower intake manifold gaskets fail, causing vacuum leaks..It can be Extremely difficult to detect these leaks, because they only leak intermittently (usually in the AM after a cold soak)... As the engine warms up they seal back up! Sometimes the vehicle will idle rough, surge or stall after initial start up, then the symptoms will clear after it gets to operating temperature... Usually there will be no driveability symptoms at all, except the engine light coming on and setting lean codes.. The gaskets have been redesigned to correct this concern..

http://engine-codes.com/p0457.html

Dec 02, 2013 | Ford Explorer Cars & Trucks

1 Answer

Error code 340 & 457


  • P0340 - Camshaft position sensor circuit malfunction.
  • P0457 - Evaporative emission control system leak detected (fuel filler cap loose/off)

    There is a bulletin #0398 posted on 05/12/2003 for P0457 - Malfunction indicator lamp (mil) illumination with diagnostic trouble codes p0442, p0455, p0456, p0457, p1442 or check fuel cap lamp illuminated with diagnostic trouble code p0457.

I'd suggest checking with your local dealer, as it may be a fix that is covered by the dealer.

My ford explorer sport trac 2001 shows codes 455 and 457, check engine on


P0455 most likely means one or more of the following has happened:
A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
Other leak or damaged piece in EVAP system

Possible Solutions:
With a P0455, the most common repair is to:
Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
Otherwise, replace the gas cap, and/or Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary.

P0457 can set by itself if the gas cap is left loose. when the engine controller sees a large increase in fuel level it knows you put some in the tank, and it runs the evaporative emissions system test to see if the system is sealed. If it sees a large leak it knows the cap was left off and sets the P0457. If you are positive the cap wasn't left even a little bit loose you may have a leak back there. It could be in the filler neck, from the tank to the evaporative emissions canisters, and from there on up to the purge solenoid. If you don't see any leaks you probably have a bad NVLD, the unit that checks the system for leaks.

What are the code manings of P0455 and P0457 for a 2003 ford mustang gt?


Both codes are for major leaks in the Evap system which vents fumes from the gas tank to the engine.
Code 455 is for a major leak, and code 457 is for the gas cap which could cause 455.
The codes can set if you run the engine with the gas cap off, or there may be a problem with the cap or other component.

I have a P0456 code on my 2003 Ford Expedition. Where is the vapor purge solenoid or the canister?


The information you are asking for varies depending on how the vehicle is equipped ie. ENGINE SIZE, AUTOMATIC or MANUAL TRANSMISSION, 2-WHEEL DRIVE, 4-WHEEL DRIVE, ALL-WHEEL DRIVE, etc.
With that said, it also deserves mention that there is a Technical Service Bulletin published by Ford Motor Company that applies to the model year and model that you have listed that involves Diagnostic Test Code (DTC) P0456.

Please note that this bulletin emphasizes the requirement of special equipment to properly diagnose and repair the DTC's listed in the bulletin. Below is a brief (partial) description of the bulletin:

ISSUE
Some vehicles may exhibit a Malfunction Indicator Lamp (MIL) illuminated with Diagnostic Trouble Codes (DTCs) P0442, P0455, P0456, P0457 or P1442 or a "Check Fuel Cap" Lamp illuminated with DTC P0457 for the Evaporative Emission System. This may be caused by loose or leaking hoses, loose or broken fuel cap, a leak at the top of the fuel filler pipe neck, etc.
ACTION
Use the Rotunda Leak Detector Smoke Machine (Part 218-00001) or equivalent, to locate and repair leaks in the Evaporative Emission System.

I have 2008 Ford Escape engine light come on check code PO 455 and PO457 and I smell gas inside car while driving.


this is an obd2 trouble code table, it can help you understand the meaning of code,
and for p0455:
Causes:
A code p0455 most likely means one or more of the following has happened:
A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
Other leak or damaged piece in EVAP system
Possible Solutions:
With a p0455, the most common repair is to:
Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
Otherwise, replace the gas cap, and/or
Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary
for p0457:
The only way a P0457 can set by itself is if the gas cap is left loose, assuming the van is in working order. when the engine controller sees a large increase in fuel level it knows you put some in the tank, and it runs the evaporative emissions system test to see if the system is sealed. If it sees a large leak it knows the cap was left off and sets the P0457. If you are positive the cap wasn't left even a little bit loose you may have a leak back there. It could be in the filler neck, from the tank to the evaporative emissions canisters just behind the subframe on the left side, and from there on up to the right front corner of the engine compartment where the purge solenoid is. If you don't see any leaks you probably have a bad NVLD, the unit that checks the system for leaks. This is probably what you are going to find.
The pressure or vacuum in the fuel tank when you remove the cap tells me that the system probably is sealed and has no leaks. Many times there will either be a little bit of pressure or vacuum in the tank, and it's perfectly normal.
The fuel gauge being innaccurate is either the sending unit or a problem with the pump module itself. there were some problems with some of the pump modules that allowed continuity between two of the terminals in the fuel pump connector and it caused the gauge to be wrong. You will probably end up needing to replace the fuel pump assembly for the gauge issue.
hope help.

An error code of 0457 came up. any idea what that is?


P0457 FORD - EVAP Control System Leak Detected (Fuel Filler Cap Loose/Off)
EVAP control system has a very large leak such as fuel filler cap fell off, EVAP control system does not operate properly.

Vehicles that meet enhanced evaporative requirements utilize a vacuum-based evaporative system integrity check. The evap system integrity check uses a Fuel Tank Pressure Transducer (FTPT), a Canister Vent Solenoid (CVS) and Fuel Level Input (FLI) along with the Vapor Management Valve (VMV) or Electric Vapor Management Valve (EVMV) to find 0.040" diameter or larger evap system leaks. Federal vehicles can utilize a 0.040" leak check rather than the 0.020" leak check required for California vehicles (click over pic for zoom).

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors

Possible causes:
- Missing fuel filler cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap

Possible solution:
- Retight or replaced fuel tank filler cap

Tech notes:
It is a very common problem with Ford vehicles. There are service bulletins for the following vehciles:
1997-2000 Ford CONTOUR
1997-2002 Ford ESCORT
1997-2003 Ford CROWN VICTORIA, MUSTANG, TAURUS
1998-2003 Ford ESCORT ZX2

What does the code p0457 for a 2005 ford sport trac mean?


check for a loose fuel cap or a rust hole at the top of the filler neck. causing a loss of pressure/vacuum.

P0457 - EVAP Control System Leak Detected (Fuel Filler Cap Loose/Off) A fuel tank pressure change greater than a minus (-) 7 inches of H 2 0 in 30 seconds has occurred after refueling; or there is excessive purge (fuel vapor) flow greater than 0.06 pounds per minute.
  • Fuel filler cap not installed on refueling (storing continuous memory DTC) and "check Fuel Cap" light may also be illuminated.
  • Fuel filler cap missing, loose or cross-threaded.
Check for missing fuel filler cap or integrity of the cap. If OK, clear continuous memory DTCs and re-initiate EVAP Emission Running Loss Monitor Drive Cycle.
