Just been reading p40 on the coolant temperature sensor. That's interesting. I've not seen seen a sensor used with dual range/sensitivity before.
Presumably there must be some bit in the PCM that stores this info when it's crossed up over the 51C threshold.
I suppose it could also be done easily with discrete components and a latch once it's passed the 1st limit.
... Does it switch back if the sensor is cooled down whilst the PCM is still powered?
