Detection Condition

WARNING: This page is about a different car, the 2003 Mazda MPV and 2002 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

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.
