I ran my error codes from my ODBII on my 2005 Ram and it came up P0157. The motor runs fine. It just bothers me to see the dummy light on.

http://www.obd-codes.com/p0157

which is Bank 2, Sensor 2. Apparently I have 4 O2 sensors.

Should I just get 1 of these and replace it? http://www.jcwhitney.com/oxygen-sensor/ ... tid=408461

Seems kind of cheap.

Should I replace all 4?
Should I put a voltmeter on first and see how much it's reading?

Bank 2 should be the left.

Sensor 2 is the one after the catalytic converter. It's also called a catalyst moniter.
