Did you get a stored code when the MIL Light came on?
What was it? Was the gas cap just loose?
You can not repair todays vehicles your self, without understanding the vehicles systems,as you found out.

How do i get the advancetrac light to go off, is their a sensor or is it in the transfer case

Christina, May just be a loose Tone ring, plug/wire,wheel speed sensor, etc. You will have to take vehicle into a good shop and have scanned for diagnostic codes to determine which sensor,wire,etc is bad and causing the advance track light to display and estimate repair. Check the attached links,instruction and guides, Good luck

2005 ford explorer had sudden loud knocking and codes P0174, P0300,P0316

Well code 174 is for a lean fuel system on bank two.
Code 300 is for a random miss and code 316 is for a miss on startup.
For some reason you may not be getting enough fuel to the cylinders on bank two, or you could have a major vac leak.

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).


- 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
1998-2003 Ford ESCORT ZX2
2000-2003 Ford FOCUS
2002-2003 Ford THUNDERBIRD
1997 F-250 Ford HD
1997-1999 Ford Ford F-250 LD
1999-2003 Ford F SUPER DUTY
2000-2003 Ford EXCURSION

Also, in this link could check this Ford Bulletin.

Hope helps (remember to rate and comment this answer).

When trying to start check fuel cap displays on odmeter

Your fuel cap is either loose or you have a bad feul cap gasket. When fueling up or after having it fueld up make sure to turn the gas cap so you hear at least 3 clicks. If this doesn't help get a new gas cap.

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.

Ford Mustang service engine soon and check fuel cap lights are on

Check fuel cap light will not immediatly go out upon replacement of the fuel cap. Might take several days. You could go to a local autoparts store and have them read the trouble code (for check engine light) and reset it. If it was indeed the fuel cap the light should stay off after resetting it. Most autoparts stores do not charge a fee to do this.

2005 Ford Tarus Check fuel cap light

I don't think this will help but I'm willing to share my experience. My gas cap light stays on all the time. I was told to buy a new gas cap. (from different stores I bought 5). Everytime I would replace the cap the light would go away for a day or 2 but returned and is still on. The Dealership said it has been happening but nothing to worry about. I have had no troubles because of it, just annoying.
