P050? Should have 4 numbers.

P0118 - Engine Coolant Temperature Sensor - High Voltage - ECT sensor most likely culprit

P0440 - EVAP System Leak Detected - Could be caused also by the faulty ECT sensor, also make sure fuel fill cap is tightened properly and not damaged

Thank you so much for your quick response. With these codes is seem that it is a fulty sensor or something to do with the air conditioning system is that correct? Also, I have a loud clinking noise someone told me it is the assembly pulley does that sound right?

ECT sensor is for the engine's cooling system, not the A/C system. Where is the noise coming from? When does it make the noise, i.E. Idling, driving, braking?
