Honda Civic Overheating? Cooling Fan NOT Turning On? (Diagnosis & FIX) How Fans Work

Is your vehicle running hotter than normal? In this video I'll show you what to check and at what temperature the fans should be coming on, I'll also explain how to test coolant temperature sensors, condenser and radiator fans and how they work with the computer to determine when to turn on. The 8th generation Honda Civic has two coolant sensors (CTS #1) and coolant temperature sensor number 2, these sensors can be easily checked with a diagnostic scan tool. I'll also show you how to test these sensors with a DVOM multimeter.
