Toyota Tundra dashboard lights flashing with O2 sensor issue indicated by scan tool on Toyota Tundra

Some Toyota Tundra owners report experiencing dashboard lights flashing due to O2 sensor issues, which can significantly impact vehicle performance. These warning lights indicate malfunctions in various systems, and ignoring them may lead to further complications. Owners have noted that a faulty O2 sensor can result in poor fuel economy, rough idling, and increased emissions.
