I am tuning an E-Force 5.7 2011 Ram. The 2/1 oxygen sensor is not reading. My alldata says that federal emissions only use 1/1 and 1/2 sensors. Is this accurate? Thank you

emissions only checks for the one side front to back, but the PCM certainly uses both fronts in fueling. Check your harness connections.
