you need a high quality scan tool to access the code..

but since its brand new, id suggest taking it in and letting warranty worry about it.

good god, you shoulda took that extended warranty. but yea since your car is very important to your job you might want to take it in and get a mechanic to get a look at it. you don't want your car breaking down in a middle of a job

DTC P0441 == P0421, P0431

DTC Set Criteria

DTC will set under following condictions: Engine speed is less than 3000 RPM. Volume Airflow (VAF) sensor output frequency is 63-169 Hz (2.4L) or 69-169 Hz (3.0L). Intake air temperature is more than 14ºF (-10ºC). Barometric pressure is more than 11 psi (76 kPa). Throttle valve is open. Engine is in closed loop control. Vehicle speed is one MPH or more. Code will set if rear Heater Oxygen Sensor (HO2S) signal becomes similar to front HO2S signal. Monitor runs for 70 seconds (2.4L) or 84 seconds (3.0L).


Probable Causes:
