P2098 Post Catalyst Fuel Trim System Too Lean (Bank 2) Medium
The P2098 code means the computer, using the oxygen sensor behind the catalytic converter, had to correct the bank 2 mixture past its limit because it saw the engine running too lean. The car usually drives normally. An exhaust leak ahead of the rear sensor is the most common cause.
