Check Engine Light Turns Off & On
I have an 04 Dodge Ram 1500 with a Hemi and just over 105K miles. I have an alternating check engine light. On for a few days, off for a few days. When I have it checked, it reads an O2 fault, bank 2 sensor 2. I have noticed no problems with the running of the truck, none at all, but this light irritates me. Is there anything I can do short of taking it for replacement?
Any help you can provide will be greatly appreciated,

To reset the PCM on an 04, pull fuse #23, put the key in and flip the ignition on-off-on-off-on and wait about about 15 secs. It should ding once and then ding 2 more times. Take the key out, replace the fuse and start the engine.
As for the pass side rear O2, look at Autozone part number 15729

You might need to clean the connectors on the O2 sensor conector might have bad connection thats why it goes off and on you hit a bump rigt and breaks contact unplug the O2 sensor and use the electrical cleaner i use brake fuildjust have to wait a little longer for it to air die then plug it back in
