Drive Cycles: Trip
WARNING: This page is about a different car, the 2002 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
Trip is defined as key on, key off event in which PCM detects a coolant temperature of more than 158°F (70°C), coolant temperature changes more than 68°F (20°C) after starting engine, and engine speed is more than 400 RPM. When PCM detects an emission-related DTC(s), it uses trip information to decide whether to illuminate MIL.
