A Toyota subsidiary has agreed to pay more than $1.6 billion and plead guilty for violations related to the submission of false and fraudulent engine emission testing and fuel consumption data to regulators and the illicit smuggling of engines into the United States.

Hino Motors will plead guilty to submitting false emissions data to regulators for more than 100,000 heavy-duty trucks. The company will pay an array of fines, and fix some affected vehicles for free.
