The automobile fault code p0495 diagnosis and fixing cost is influenced by the estimated repair time of 1.0 hour.

Most auto repair shops charge between $75 and $150 per hour for their services.

The P0495 fault code indicates that the cooling fan speed is too high. This is caused by a problem with the cooling fan relay and the cooling fan clutch solenoid voltage control circuit. The cooling fan relay sends a PWM signal to the cooling fan clutch, which controls the speed of the fan.

The signal is controlled by the Engine Control Module (ECM) and adjusts the position of the oil control valve in the fan clutch housing.

If the clutch fluid pump-out, which is the time it takes for the fan clutch to disengage completely, exceeds a certain range, the fault code will be triggered. This range is 10 minutes at sea level to 52 minutes at elevations of 6,500 ft.

What are the possible causes of the p0495 fault code and how can they be identified?

If you’re experiencing the p0495 fault code, indicated by the Engine Light or Service Engine Soon Warning Light turning on, there are a few possible causes to consider. It could be a faulty Cooling Fan Relay, an open or shorted Cooling Fan Relay harness, a poor electrical connection in the Cooling Fan Relay circuit, a faulty cooling fan clutch, or a faulty control unit. To identify the cause, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the connectors.
