What are the common causes of P0B96?

An S circuit voltage reading outside the expected window. A drifting S voltage tap. A high resistance joint in the S sense lead. A weak cell at the S tap. A calibration fault in the S sense channel.

Compare S circuit voltage to adjacent taps. Monitor S voltage across a drive cycle. Inspect the S sense lead for added resistance. Test the S cell tap under load. Replace the sense module if S stays out of range. Clear the code and retest.
