What does Check Engine Light code 1170 mean?

What does Check Engine Light code 1170 mean? What do I need to do to fix it. 1996 BMW 218i - 4 door sedan

I searched for this code and cannot find a matching result for BMW. Here’s what I found:

ME7.2 P1170 Post Catalyst Fuel Trim System Correction Value above Threshold (Bank 2)

P1170 Front Heated Oxygen Sensor Stuck.

P1170 Bank to Bank Fuel Trim Offset

P1170 ESO - Engine Shut Off Solenoid Fault

What is the full code? The letter at the start is important. Is it “P” as was assumed?
