How many o2 sensors do you have in your 2005 Hyundai Santa Fe?

The 2005 Hyundai Santa Fe typically has four oxygen (O2) sensors: two upstream (pre-catalytic converter) and two downstream (post-catalytic converter). These sensors help monitor the engine's air-fuel mixture and the efficiency of the catalytic converter. However, it's always good to check the specific engine configuration, as the number may vary slightly depending on the engine type.
