Citroen C3 - heater faults - mikien

i have a 2009 citroen c3 with a 1.1 engine recently when starting the car first thing it would revv upto about 2500 - 3000 rpm and then drop down also the heater was blowing cold, i have had it on a modis scanner and it says the rpm is at 2000+ even when its dropped back to idle, and the oil and coolant temp is constantly at -40 degrees so i changed the coolant temp sensor and this has made no differace any help would be apperciated

thanks mike

So did the scanner actually say replace the sensor or has the system been tested beyond what the scanner sees.Scanners are clever but they have no brain.

The low coolant temperatures and the cold heater would suggest that the thermostat has failed.
