July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Diagnosis & Repair

Retrieve trouble codes. See RETRIEVING DIAGNOSTIC TROUBLE CODES  under SELF-DIAGNOSTIC SYSTEM. If other codes are displayed, diagnose and repair those codes first and retest. If only DTC P0116 is displayed, check thermostat. If thermostat is okay, replace ECT sensor and retest.
