Ford Code P0495

When you’re having trouble with your Ford vehicle and the diagnostic code P0495 is shown, it could be due to Fan Speed High. This DTC is triggered when the indicated fan speed is higher than the calibrated value during the key ON, engine running (KOER) self-test. It could be caused by mechanical binding or a damaged Fan Speed Sensor (FSS). To diagnose the issue, it is important to check if the fan freely rotates on the clutch. The related service bulletin SSM47999 can also help troubleshoot the issue.

Causes and Solutions of Ford Code P0495

Cause Solution
Mechanical binding Check if the fan is freely rotating on the clutch.
Damaged FSS Replace the Fan Speed Sensor.
Incorrect calibration Check the calibration of the Fan Speed Sensor.
Faulty wiring Inspect the wiring to the Fan Speed Sensor and replace if needed.

Mechanical Binding

If the fan is not freely rotating on the clutch, it could cause the Ford code P0495. This is because the fan is not able to reach the speed necessary to meet the calibrated value. It is important to inspect the fan to ensure it is able to rotate freely. If the fan is not able to rotate freely, the cause must be identified and fixed.

Damaged Fan Speed Sensor (FSS)

The Fan Speed Sensor (FSS) is responsible for determining the fan speed. If it is damaged, it could lead to the Ford code P0495. The FSS must be tested to determine if it is functioning properly. If it is not, it must be replaced to fix the issue.

Incorrect Calibration

If the Fan Speed Sensor (FSS) is not calibrated correctly, it can cause the Ford code P0495. The calibration of the FSS must be checked to ensure it is set to the correct values. If not, the calibration must be adjusted to the correct values.

Faulty Wiring

If the wiring to the Fan Speed Sensor (FSS) is faulty, it could lead to the Ford code P0495. It is important to inspect the wiring and replace it if necessary. If all the wiring is in good condition, the issue is likely not caused by wiring.

Conclusion: Resolve Ford Code P0495 with Careful Diagnosis

Ford code P0495 can be caused by a variety of issues, including mechanical binding, damaged Fan Speed Sensor (FSS), incorrect calibration, and faulty wiring. To diagnose the issue and resolve Ford code P0495, it is important to carefully inspect the fan, FSS, and wiring. If any of these components are found to be faulty, they must be replaced or adjusted to fix the issue. Using the right diagnostic methods and parts is the key to resolving Ford code P0495.
