P2189 System Too Lean at Idle (Bank 2) Medium
The P2189 code means the air-fuel mixture on bank 2 is too lean while the engine is idling. The computer ran out of room to correct the mixture in that specific condition, and that detail is a big help in finding the cause. You can usually keep driving for a short time with caution.
