The DEQ Too™ test option uses telematics devices to transmit OBD data without the motorist visiting a Clean Air Station. With DEQ Too, test data is remotely delivered from a service provider to DEQ for electronic evaluation and a pass/fail determination. This test method is now available at more than 200 automotive repair facilities, car dealerships and a wide range of other business locations in the Portland and Medford metro areas.
