What is your question?
12-18-12 1st they replaced the valve-purge control for code P0456, said they tested the valve and it was not holding. On 12-20-12 the check eng. light was on again. I Plugged in my OBD and it showed 2 codes P0456 and P0456pd. I went back to dealer on 12-21-12 and told them my check eng. light was still on. Came back to me and told me that I had a P0442 code and said that I needed a new gas cap. I told them that I had already replaced the cap with a non OEM brand and they told me it was bad. I told them that I checked the codes before I brought my car in and the only codes that came up were p0456 and p0456pd not P0442. I told them I was not going to pay for the new gas cap because of my not seeing that code before I brought it to them. No charge and sent me off. Got gas on 1-7-13 on 1-9-13 the check eng. light came on again. On 1-14-13 brought car back to dealer for the 3rd time with the same 2 codes. Asked for a smoke test, which they did. They also replaced my ccv valve (canister close valve) and road tested my car, drove it 20 miles. No codes detected (they said). On 1-30-13 check eng. light came on again. I haven't brought my car back to the dealer yet partially because I had not been feeling well. I recently found a hose clamp on the purge valve that could have been tighter so I put on another clamp, erased the code and am now waiting for the check eng. light to come on again after I drive 50 to a refill my tank. Any ideas what the problem could be?

take it back and adv them you still have issues, should be under warranty
Here is the text from a Kia Technical Service Bulletin that may help: OPTIMA(MG) >2007 > G 2.4 DOHC > Purge Control Solenoid Valve (PCSV) Monitor DTC Status If any codes relating to Fuel tank pressure sensor, Canister closing valve or PCSV circuits are present, do ALL REPAIRS associated with those codes before proceeding with this troubleshooting tree. 1. Start engine to normal operating temperature Evaporative Emissions Systems (EVAP) Leak Tests can be run by the Scan Tool. The tests are automated and provide either a pass-fail result or directions to check for DTCs. 2. Install scan tool and clear DTC 3. Perform "EVAP. LEAKAGE TEST" mode referring to enable conditions as below EVAP. Leakage Test enable conditions - Following conditions must be fulfilled to start the test. 1) Engine warm up at Idle Status 2) No relevant DTC 3) Fuel level is below 80% 4. Is DTC P0456 set again? YES â–¶ Go to next step as below NO â–¶ Fault is intermittent caused by poor contact in the sensor's and/or ECM's connector or was repaired and ECM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure
Same problem I had on my 2007 Kia sedona I found most all of my hoses at the fuel vapor box were dry rotted one hose was just hanging broken off all the gas fumes were getting into the van. There are four 10mm screws on the cover once you pull that off you can see all the hoses going to the box.
This is going to sound crazy, but I have a 2006 Kia Spectra SX. About 3 or 4 years ago my check engine light came on so I took it to a dealer. I was told it was the vapor recovery system and it had spiders in it. I knew that was a lie, but it still cost me $85.00 and a carton of cigarettes stolen from my trunk. Anyway, I researched the problem, changed gas caps, check system parts etc. but still I had an intermittent check engine light (went off when I would fill tank and come back on when the gauge went down about an eighth of a tank and so on). Around the 3rd of Oct. this year I was checking under the hood before a long trip to the doctor. The only thing I found was my windshield wiper fluid was kind of low. I filled the fluid bottle (maybe a little too full by accident), and after the trip and a couple of days later I told my wife that I had not seen the check engine light on since before the trip. The check engine light stayed off the whole month of Oct. Just the other day it started it's intermittent crap (light was on when I parked), so i filled the windshield washer tank all the way to the top again and the light went out and has stayed out. I don't know for sure, but the only thing I can figure is Kia decided to connect their low windshield washer fluid sensor to the check engine light. There is no other explanation since that is the only thing I have touched under the hood for months. By the way, my fluid level doesn't have to get very low for it to set off my check engine light, so I am thinking that something is not working right with that sensor. If there is in fact a sensor there.
