P1480 Infiniti Code - Cooling Fan Speed Control Solenoid Valve Circuit
Quick Answer
The P1480 Infiniti code indicates a problem with the cooling fan speed control solenoid valve circuit in the vehicle. Common causes include Faulty cooling fan speed control solenoid valve: The solenoid valve itself may be defective and not functioning correctly, Wiring issues: Damage to the wiring harness or connectors in the circuit can disrupt the flow of electrical signals and trigger the code, Engine control module (ECM) failure: A malfunction in the ECM, which controls the cooling fan operation, can lead to the code being triggered. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1480 Infiniti Description
The P1480 Infiniti code indicates a problem with the cooling fan speed control solenoid valve circuit in the vehicle. This solenoid valve is responsible for controlling the speed of the cooling fan, which helps regulate the engine's temperature by cooling the radiator. When this code is triggered, it means that there is an issue with the circuit that controls the solenoid valve, which can lead to problems with the cooling system.
Common Causes of P1480 Infiniti
- Faulty cooling fan speed control solenoid valve: The solenoid valve itself may be defective and not functioning correctly.
- Wiring issues: Damage to the wiring harness or connectors in the circuit can disrupt the flow of electrical signals and trigger the code.
- Engine control module (ECM) failure: A malfunction in the ECM, which controls the cooling fan operation, can lead to the code being triggered.
- Overheating: Continuous overheating of the engine can put stress on the cooling system components and lead to the code being triggered.
- Cooling fan motor failure: If the cooling fan motor is faulty, it can affect the operation of the cooling fan speed control solenoid valve.
Symptoms of P1480 Infiniti
- Engine overheating: The most common symptom associated with this code is the engine overheating. The cooling fan may not operate at the correct speed, leading to inadequate cooling of the radiator.
- High engine temperature gauge readings: If the engine temperature gauge shows higher than normal readings, it could indicate a problem with the cooling fan speed control solenoid valve circuit.
- Reduced air conditioning performance: The cooling fan also helps cool the air conditioning condenser. If the fan is not operating correctly, the air conditioning performance may be affected.
- Check engine light: The illumination of the check engine light on the dashboard is a typical symptom of this code being triggered.
How to Fix P1480 Infiniti
- Diagnose the issue: Use a scan tool to retrieve the code and perform a visual inspection of the cooling fan speed control solenoid valve circuit components.
- Test the solenoid valve: Check the operation of the solenoid valve to determine if it is functioning correctly.
- Inspect wiring and connectors: Ensure that there are no damaged or loose connections in the circuit.
- Replace faulty components: Replace any components that are found to be defective, such as the solenoid valve, wiring harness, or connectors.
- Clear the code: After completing the repairs, clear the code from the ECM's memory to reset the system and ensure that the issue has been resolved.
Cost to Fix P1480 Infiniti
The cost of repairing the cooling fan speed control solenoid valve circuit can vary depending on the extent of the issue and the specific components that need to be replaced. In general, the parts for this repair can range from $50 to $200, while the labor costs can be between $100 and $300. Overall, the total repair cost for this issue is typically around $150 to $500. It is important to note that the actual costs may vary based on the vehicle's make and model, the location of the repair shop, and any additional services required. It is recommended to obtain quotes from different auto repair shops to get a more accurate estimate for this repair.
