Hello Scotty,
How often should O2 sensors be replaced? I have a 2010 Jeep Liberty. Codes I have are P0302 and P0420. 260,000 miles. I have never replaced the O2 sensors. Just replaced spark plugs, wires, and coil packs.
Thanks,
I love your channel!

You never address O2 sensor codes without first fixing the causes of any other codes . You have a misfire code which needs to be resolved.
O2 sensors only need to be replaced when they fail.
I have a 2001 Ranger with just under 200,000 miles. It still has the original O2 sensors
