In the exhaust stream, their positioning varies depending on what vehicle we are talking about. The computer uses the O2 sensor(s) to trim the air/fuel ratio.

i dont know what the code means im sure someone does but i know that you can rent a O2 sensor socket and tool from autozone or other parts stores also if u run the vehicle till the exhaust pipe gets hot that will make it come out easier and there is always penetrating oil also (just be careful with flamable stuff on hot exhaust pipes!)

and if u can find out what u clean them with i know that the inside has two platnuim strips and the outside is ceramic so i have no idea what can clean the combination without messing it up

41 means the right bank is running lean.

I just needed to mention that if you have a O2 after the cat its for monitoring the cat efficiency only, has nothing to do with A/F mix.

How do you know you need new O2 sensors? For the Bosch about $50 but they don't last very long, for OEM about $110, you have 4

Hi coralbayy and Welcome to FTE! Please take a moment to check out the Guidelines as they contain important info that you'll need when posting on the site:

https://www.ford-trucks.com/guidelines.html

I'm seeing prices of about 46 bucks for the Bosch up to around 65 for other brands.
