Code P1102 Land Rover Description
The P1102 diagnostic trouble code (DTC) for Land Rover vehicles indicates that there is a problem with the Mass or Volume Airflow Supply being too low. This means that the engine control module (ECM) is receiving a signal from the Mass Airflow Sensor (MAF) that the amount of air entering the engine is insufficient, which can lead to a variety of performance issues. The MAF sensor is a crucial component that measures the amount of air entering the engine, allowing the ECM to adjust the air-fuel ratio for optimal combustion.
