The number of O2 sensors on a GMC Sierra 2500 typically depends on the engine configuration and model year. Most commonly, there are four O2 sensors: two upstream (pre-catalytic converter) and two downstream (post-catalytic converter). However, specific configurations may vary, so it's always best to check the vehicle's service manual for accurate information.
