My check engine light is not on , but I checked the codes anyways and saw the 17 among with 12 (battery disconnected) and 32 (EGR), 17 which is ENGINE STAYS COOL TOO LONG just appeared today and I am not sure if it's a real problem. It could be bad thermostat or coolant sensor like it says in the code description but maybe it's just because of extremely cold weather? My car was standing 3 days in -20C with windchill going down to -40C before I got new fuel pump, then I parked the car in the garage.
What do you think ?
