The kit covers all four bank positions: pre-cat (upstream) and post-cat (downstream) sensors for both the left and right cylinder banks on the LF4 \/ LFX 3.6 L V6. Each sensor feeds exhaust oxygen data back to the ECM to maintain closed-loop fueling and monitor catalyst efficiency.\u003c\/p\u003e\n\n\u003cp\u003eReplacing all four sensors at once clears persistent O2-related DTCs (P0130 \/ P0150 \/ P0136 \/ P0156 family), restores fuel economy, and brings a tired ATS back to factory-cruise smoothness.
