P 0420 code question?
I did a little research on here about this code shown above and iv gotta a few other questions. Its a code that is showing on my wife's 05 2wd hemi ram. Can she still drive the truck or will i have pull the o2 sensor out and replace it first?? Its seems not a big code to worry about from what iv seen on other posts. I take it it is the sensor on the driver side from what iv read. Is there any more info i might have missed anyone can give me? the truck seems to be fine and hasnt lost anything from what she can tell. any help would be great. thanks
