I wish it was so simple.
Of course the code is for coolant temp. The reference to oil is made as a reminder that the oil temp is much more important in terms of WEAR, as you don't want it too cool.
The PO128 code is tripped by 3 trips with no full warmup (under 180 degrees) in ten minutes.
It will also clear itself with three good trips. My car is very sensitive to this and requires a blast or two to assure proper temp is reached with my Motorad 4127.
