Code P0102 2007 Toyota Camry Description

The P0102 diagnostic trouble code (DTC) for a 2007 Toyota Camry indicates a problem with the Mass or Volume Air Flow Circuit, specifically a low input signal being detected by the Engine Control Module (ECM) or Powertrain Control Module (PCM). The Mass Air Flow (MAF) sensor is a crucial component in the vehicle's fuel injection system, responsible for measuring the amount of air entering the engine to ensure the proper air-fuel mixture for combustion. When the ECM detects a low input from the MAF sensor, it can lead to a variety of performance issues and potential long-term damage if left unresolved.
