Just because you got a 2-1-2 code doesn't mean you need to change the O2 sensor. Been down that route and it can get pricey. Check the O2 sensor out with a mulitmeter and see if the volts are between .1 and .9 staying close to .5 volts. It your sensor is giving proper voltage look else where. Check FAQ section.
