Code P0102 Jaguar Description

The P0102 Jaguar diagnostic trouble code (DTC) indicates a low input signal from the Mass Air Flow (MAF) sensor in the vehicle's engine. The MAF sensor plays a crucial role in measuring the amount of air entering the engine to determine the appropriate fuel injection for combustion. When the MAF sensor detects a lower than normal airflow, it can result in a lean air-fuel mixture, leading to poor engine performance and efficiency.
