Actually I believe the code has something to do with fuel.. the P0237 means Powertrain (P), the 0 means its a common code throughout all vehicles not manufactur specific and the 2 means Fuel , the 37 is the specific code and says the problem usually that i dont know off hand but if theres like a lack of power or you know this is creating a misfire i would start out by checkin fuel pressure [pressure, pump, rails] and then fuel delievery [injectors].
hope that gets you started or an idea maybe
ps a turbo is something you usually install yourself so the car shouldnt be equipped with a turbo sensor...i dont think that exists

SOURCE: Fuel Relay
It is in the passenger compartment relay box under the left side of the dash. Along one edge there are 6 rectangular relays grouped 2 together and 4 together. The fuel pump relay is second over from the gap between the 2 groups of relays. My diagram marks it as CMI 12.

If you are talking about the thermo electric cooling fan, its operation is independent of the car's electical system. It is switched on and off by the engine temperature. When you park, the engine heat soaks upward to heat the thermostat turning the fan on. It will run until the engine cools down and the thermostat switches it off.
