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 .

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:

This article supersedes TSB 03-9-8 to update the vehicle lines and Service Procedures.
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 the P0456 on my dodge caravan sxt 2007 with the keys.


http://www.obd-codes.com/p0456

This is usually caused by a gas cap that was not put on properly after a fill up. If this is the case then simply tighten the gas cap and the check engine light should go out in a few days with regular driving or reset with a code reader. You may have to replace the gas cap if the code remains. be sure to get the correct cap.

The Dodge P1494 engine light code means Leak Detection Pump Switch or Mechanical Fault.

A proper diagnosis must be done, you can't simply replace the LDP and expect that to fix the problem. It shouldn't hurt anything to keep driving it for a while until you can get it fixed.

There is a technical service bulletin that applies to your vehicle and it mentions that code specifically. I'm including it here for your information:

TSB-18-01-00
SUBJECT: Misdiagnosed Leak Detection Pump Systems With DTC P1494, P0442, P0455, OR P0456.
MODELS:
1997 - 2000 (LH) Concorde/Intrepid/LHS/300M/Vision and others!

DISCUSSION: During evaporative system diagnosis, Leak Detection Pumps have mistakenly been replaced. A thorough inspection for pinched, kinked, or disconnected supply vacuum lines (as currently listed in the Powertrain Diagnostic Procedures) is a critical step in diagnosing DTC P1494 (LDP SW OR MECHANICAL FAULT). Additionally, the other evaporative leak faults (DTC P0442 - SMALL LEAK, P0455 - LARGE LEAK, and P0456 - VERY SMALL LEAK) should have the supply vacuum lines examined for pinches or kinks prior to any LDP component replacement. The supply vacuum lines should be checked from the engine compartment all the way to the fuel tank, including the LDP and purge system.

NOTE: VERIFY ALL RELATED SUPPLY VACUUM LINE ROUTINGS FOR PINCHES, KINKS, OR DISCONNECTION'S BEFORE REPLACING LDP SYSTEM COMPONENTS.

I have a couple of check engine light codes that came up. p0456, p0700, p1794. what are these and are they in anyway related to each other. does anyone have any solutions besides going to a dealer or...


P0456 A small Evaporative Emission Control System leak has been detected P0700 Transmission Control System Malfunction P1794 is: Powertrain Control Module Battery Direct Power Circuit

Now, what can we find from all of these.....the first one p0456...mostly refers to improper sealing of the gas cap, so replace this fairly cheap....
now 0700 normally refers to a transmissioin fault..but the third one p1794 refers to battery power...so I would be first checking to see if battery charging system is functioning correctly.....a charging rate at idel should be 13.8-14.4v......as the 0700 code could be related to this issue.....check the transmission fluid.......should be cherry red, not smell burnt or brown.......is this car regularly serviced.......if so, what does the vehilce do that leads you to think there might be a problem....apart from the engine light.....

Lastly, these codes may not be current ones, but maybe you started the car with the gas cap off, for instance and it logged this code..so see if you can clear them, and see what remains behind.

Code P0456 on 2003 Town & Country


Below are the possible causes for your engine light and error code:

Possible Causes:
  • EVAP fuel tank or canister vapor hoses leaking or damaged
  • EVAP system component leaking, fuel cap loose or missing
  • Leak detection pump damaged or leaking

The fuel cap is probably the most common cause of this problem. It's considered part of the emission system and if faulty or not place on the filler tube correctly, it will throw an error. Best of luck with your engine light issue. Take care!
