Detection Condition

PCM monitors maximum and minimum value of engine coolant temperature, 5 minutes after engine start up (maximum) and after vehicle has been cold soaked (turned off) for 6 hours or more (minimum). If ECT sensor maximum and minimum values is less than 42°F (5.6°C), DTC is set. This is a continuous monitor. MIL is illuminated if PCM detects malfunction in 2 consecutive drive cycles.
