I wouldn't replace the sensors until you know they're bad. You'll know a sensor needs replacing when the PCM actually conducts the test on the sensors and pops the CEL on. By replacing a sensor, it will not speed up the test of the sensor. The tests of the systems, or sensors, only gets done after certain driving situations. Meaning both city & highway driving, or whatever Dodge requires before the test will be conducted.
I had the same problem on both my car & truck last year, same two sensors. The truck I got through on the second try, but my car was another story. I got it to pass on my fourth try! I forgot how many miles it was, but what a PITA.
Don't worry, you'll either get the CEL or pass inspection, hopefully the latter.
