Code P2098 Lincoln Description
The P2098 diagnostic trouble code (DTC) for Lincoln vehicles indicates that the post-catalyst fuel trim system on bank 2 is reading a lean condition. This means that there is an imbalance in the air-to-fuel ratio after the catalytic converter in the second bank of cylinders. The fuel trim system is responsible for adjusting the amount of fuel injected into the engine to maintain the optimal air-fuel mixture for combustion. When the system detects a lean condition, it means that there is too much air and not enough fuel in the mixture, which can lead to poor engine performance and increased emissions.
