Code P2199 Lincoln Description

The P2199 diagnostic trouble code (DTC) for Lincoln vehicles refers to the "Intake Air Temperature Sensor 1/2 Correlation." This code indicates that there is a discrepancy between the readings from the two intake air temperature sensors in the vehicle. In modern vehicles, there are typically two intake air temperature sensors - one before the throttle body and one after. These sensors play a crucial role in the engine's operation by providing data to the engine control module (ECM) to calculate the air-fuel mixture for combustion.
