P0495 DescriptionThe Cooling Fan Relay sends a Pulse Width Modulation (PWM) signal (12-14 volts) to the cooling fan by the cooling fan clutch supply voltage circuit. The Powertrain Control Module (PCM) uses the PWM signal, which controls the speed of the cooling fan clutch by controlling the position of the oil control valve inside the clutch. If the cooling fan clutch RPM is to high when the PCM is commanding 0%, the Diagnostic Trouble Code (DTC) will set.
