AUC Fault and HVAC Issues After Sensor Replacement

Having issues with the heaters not getting hot scanned vehicle had fault with auc sensor i have changed this but fault still there

Start by checking the coolant level and ensure there are no air pockets in the system, as these can affect the heating performance. If the coolant level is low or there are air pockets, it can prevent the heater from working properly. Let me know how it goes or if you have any further questions!
