Good to hear the car is back on track.
Regarding oil temps and water coolant temps, those two are not the same thing. Limp mode from too high oil temperature won't happen until it's above 300F. However, limp mode from too high coolant temps is 117F, but there is no gauge available for this, you either need to log it through a ODBII tool or get the performance steering wheel. If the water pump is malfunctioning, it will most likely have an effect on oil temps as well, but in this case I assume that either coolant temps went up too high, or that the car limped because it could not communicate with the water pump.
More details regarding limp modes and specific temperatures can be found in the engine management pdf available in this thread:
