P0456 is a code set when there is a very small leak (theres very small leak, small leak and a couple of others, your code indicates the smallest level of leaking). This can be caused by a vacuum line that is cracked or otherwise leaking on the evaporative (EVAP) system. It could even be from a gas cap that is not sealing properly, though typically a gas cap leak tends to set code P0441. Just the same, and since it is the cheaper way to go, start by replacing the gas cap and see if that clears the code and any check engine light you may have.

Once you replace the gas cap you may need to disconnect the battery for a couple minutes to reset everything if you dont have access to a scanner that can do it.

If you still have the 100 mile warranty go back to kia , if not this is an emissions evap issue , very small leak detected , could be as simple as a loose gas cap , but , hope your under warranty .

My mother has an old 11.5 HP Cox Stockman. Just today, the main drive belt has become coming off, (3 times in a row so far) Please advise possible problem and solution. Thanks.

It is possible the belt is not correctly tensioned or perhaps the belt is in poor condition.

Sometimes pulleys can move along a shaft a little so they are not correctly aligned. Checking pulley alignment with a straight edge is an important part of fault-finding and maintenance of vee belt and pulley systems. Once the alignment is found to be correct a belt of the correct type is fitted and correctly tensioned the troubles should be at an end.

Change spark plugs fuel filter fuel pump engine can not start

Wow! You've really got your hands full! 1) Verify the fuel pump is installed correctly and has power. 2) Verify the fuel filter is installed correctly. 3) Verify the spark plug wires are correctly installed. The number one reason for a car not running after an owner changes the spark plug wires - the wires were not installed to the correct cylinder.

About my 2000 rodeo 2.2l. everything is correct. the timing are correct, but the cam shaft sprocket are not the same. the exhaust side is correct, but the intake side is not the same. i'm talking

The best thing to do here is to access the factory repair manuals to see how to set the cams up. To do this go here. There is a small charge for the service

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:

Article No.
P0456, P0457, P1442 OR CHECK FUEL CAP LAMP
FORD: 1997-2000 CONTOUR 1997-2002 ESCORT 1997-2003 CROWN VICTORIA, MUSTANG, TAURUS 1998-2003 ESCORT ZX2 2000-2003 FOCUS 2002-2003 THUNDERBIRD1997 F-250 HD

2002-2003 BLACKWOOD
1997-1999 TRACER
1997-2000 MYSTIQUE
1999-2002 COUGAR
This article supersedes TSB 03-9-8 to update the vehicle lines and Service Procedures.
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.
Use the Rotunda Leak Detector Smoke Machine (Part 218-00001) or equivalent, to locate and repair leaks in the Evaporative Emission System.
