Upstream and downstream O2 sensors the same. Upstream sensor failed after 5,000 miles but downstream still running strong. Replaced Delphi with MOPAR sensor per advice of service tech that informed me the emissions and throttle body responses (final trim adjustment) are much better with the Mopar sensor on the 2.4 and 2.0 L VVT engines and he does not get come-backs like he did with all other sensor brands. (I believed him and did as recommended since the Bosch O2 sensors also tripped emission codes weekly but real time emission checks in OEM lab proved otherwise.) Normally Delphi and Bosch O2 sensors are very good..... Just not in the 2.4 and 2.o VVT.
