Monitored & Set Conditions
WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
Fuel system lean condition is monitored when engine is running in closed loop, ambient/battery temperature sensor reading is more than 20°F (-7°C) and altitude is below 8000 feet. DTC will set when PCM multiplies short term compensation by long term adaptive and a certain percentage is exceeded. A freeze frame is stored and the MIL illuminates.
