p0420
Hey Guys,
Had the check engine light in the 2005 F150 (90,000 miles) come on. Got the code checked and its P0420. I know that has to do with the cat threshold levels etc. so i believe im looking to replace the o2 sensor, if im not mistaken.
How hard of a job is this? Ive done a decent amount of engine work and worked in a shop in high school. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.
Also I know its the right bank, but if im not mistaken there is a before and after the cat o2 sensor, which do i replace? Both?

ok thanks for the info, i was told it was the right bank, but is that right from standing in front of the vehicle or right from the drivers perspective? im thinking it from standing in front of the vehicle but i want to make sure.
