P0128 Coolant ( Coolant Temp Below Thermastat Regulating Temp

[Scottie]

I got a buddy to scan the engin light for me came back P0128 Coolant ( Coolant Temp Below Thermastat Regulating Temp. What do you think should I drive to Brampton on Tuesday or try to get it fixed first? it is about a 2 hour drive for me.

P0128 only means the engine temperature did not get up to proper operating parameter when the sensor was polled. You probably knew this (a simple search will tell you this).
The key here is that you need to watch the engine temps. It is running too cool and it could be because the sensor was polled too early and then you quit driving or, your thermostat is stuck open. Either way, it is not an engine killer. Just check your coolant level and make sure there are no leaks
Clear the light and go on your trip. Chances are it will not come on again and if it does, it is not a big deal. Just get your thermostat replaced before winter.
