Fault code P0102 indicates a low voltage signal from the mass air flow (MAF) sensor, often due to issues like a faulty MAF sensor, damaged wiring, or a clogged air filter. To resolve this, start by inspecting the MAF sensor and its wiring for any visible damage or disconnections. Clean the MAF sensor with appropriate cleaner and ensure the air filter is not obstructed. If the problem persists, consider testing or replacing the MAF sensor itself.
