Hi there:DTC P0068 - Throttle Body Airflow Performance
The ECM detected that the airflow was more than the calculated airflow rate, condition met for 0.2 second. In this diagnostic, the actual throttle position and airflow rate are compared to an expected throttle position and airflow rate based on the engine load. The ECM determines engine load based on inputs from the mass airflow (MAF) sensor and the manifold absolute pressure (MAP) sensor. The ECM performs further comparisons to determine if a sensor has failed, and then it sets DTCP0068.
Hope this helps.
Testimonial: "Thanks so much for your help. What about the other error code P0108?"

thats not typical.
actually it looks like someone may have done some service and disconnected some things to make all those codes set like that.i would recommend resetting the codes to be sure they are all true issues.then solve them one at a time.put a obd2 on it and clear all codes and then drive it about 20 or 30 miles.
SOURCE: my engine light came up with the code P0068 AND
p0068 TPS sensor problem,p0108 maf or baro sensor higt resistance,usually one or other has voltage problem or its desconected,you should check for voltage, disconecting one firs tand after the other one.

okay lets start with the po 068 & po 108, check the connection to the mass air flow sensor if conn are good replace the mass air flow sensor, that should solve the two codes, now the po455 is a evap gross leak detected. first is to make sure gas cap is good and on tight, i f it is then look for broken evap lines or hoses, it a line that sends vaccum to evap canister and another line that send fuel vapors to engine and canister check lines, also there are valve that you should check vent and purge valves, this part you may need a shop to test valves, hope this is helpful,

There is a TSB for this issue: It is in "limp" mode. It is not unusual for the Sebring - Should be covered by Chrysler.
TSB Number: 0801505

Check engine light usually means some failure in emissions control
system. Kia will have to hook up and get diagnostic code or codes.
