Per the OBDII manual: "Warm up is characterized by two specific requirements. After the engine is started, the coolant temperature must reach 160-degrees Farenheit and the ECM must see an increase of 40-degree or more in coolant temperature. If the engine is started and is already at 130-degrees that would not constitute a warm-up to the ECM".
