The 6-pin 1.5mm series connector used on radiator fan motors, coolant temperature sensors, and engine management harnesses is a known failure point on high-mileage vehicles. Connector corrosion or locking tab failure causes intermittent or permanent loss of the cooling fan signal, triggering overheating conditions and \u003cstrong\u003eP0480–P0483\u003c\/strong\u003e (cooling fan relay circuit) fault codes.
