Monitored & Set Conditions

Ambient air temperature sensor circuit is monitored with ignition on, engine coolant temperature more than 160°F (71°C) and no Inlet Air Temperature (IAT) sensor faults present. DTC will set after 5 warm cycles, odometer mileage has increased 196.6 miles and inlet air temperature has increased less than 37.4°F (3°C). A warm cycle is when engine coolant temperature increases from more than 40°F (4.4°C) to a minimum of 160°F (71°C). This is a 2-trip fault. See TRIP INDICATOR  under ON-BOARD DIAGNOSTICS under SELF-DIAGNOSTIC SYSTEM.
