OBD code P0172 indicates that the engine control module (ECM) has detected a rich fuel condition, meaning there is too much fuel or not enough air in the air-fuel mixture. Common causes include a malfunctioning fuel injector, a faulty mass air flow (MAF) sensor, a clogged air filter, or issues with the fuel pressure regulator.
