P0115 is coolant temp voltage low.Most common is a faulty coolant temp sensor .I would start by replacing the coolant temp sensor.If there is still an issue it could be the wiring going to the sensor.This is what they need to check next.

Hoped this helped.

Positive feedback and bonuses greatly appreciated.
