O2 sensor problems - 7/28/2008 4:00:33 AM

Just put a 2003 2.7 V6 into a 2002 Santa Fe. Check engine light comes on and code reader shows error on all 4 O2 sensors. P0031 and P0057. Low temp. Could they all be bad? Could the computer on the 02 be looking for different readings than the 03? What should I do???
