Code P1501 Subaru Description
The P1501 code for Subaru vehicles indicates a malfunction in the Radiator Fan Relay 2 Circuit. The radiator fan plays a crucial role in maintaining the optimal operating temperature of the engine by cooling the radiator. The relay 2 circuit controls the activation of the radiator fan, and if this circuit malfunctions, it can lead to overheating of the engine.
Common Causes of P1501 Subaru
- Faulty radiator fan relay
- Wiring or electrical connections issues
- Defective temperature sensor
- Blown fuse related to the radiator fan circuit
- Corrosion or damage to the radiator fan components
Symptoms of P1501 Subaru
- Engine overheating
- Check engine light illuminated
- Poor fuel efficiency
- Engine performance issues
- Radiator fan not turning on when the engine is hot
How to Fix P1501 Subaru
- Diagnose the issue by using a scan tool to determine the specific cause of the malfunction.
- Inspect the radiator fan relay, wiring, and electrical connections for any damage or corrosion.
- Test the temperature sensor to ensure it is functioning correctly.
- Check and replace any blown fuses related to the radiator fan circuit.
- Replace the faulty radiator fan relay or any damaged components as needed to resolve the issue.
Cost to Fix P1501 Subaru
The typical repair costs for addressing a Radiator Fan Relay 2 Circuit Malfunction can range from $150 to $400, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type.

Frequently Asked Questions about P1501 Subaru Code
1. What does the OBDII code P1501 mean on a Subaru?
P1501 indicates a "Radiator Fan Relay 2 Circuit Malfunction," meaning the engine control module (ECM) has detected an issue with the electrical circuit controlling the second radiator fan relay.
2. What are the common symptoms of the P1501 code on a Subaru?
Symptoms may include the radiator fan not working properly, engine overheating, an illuminated check engine light, and potentially reduced air conditioning performance.
3. What causes the P1501 code to appear on a Subaru?
Common causes include a faulty radiator fan relay, damaged or corroded wiring or connectors, a blown fuse, or a malfunctioning ECM.
4. Can I drive my Subaru with the P1501 code active?
Driving with this code is not recommended, as it may result in engine overheating, which can cause severe engine damage if not addressed promptly.
5. How do I diagnose the P1501 code on my Subaru?
Start by inspecting the radiator fan relay, associated wiring, and connectors for damage or corrosion. Check the fuse for the cooling fan circuit and use a multimeter to test for proper voltage and continuity.
6. How do I fix the P1501 code on a Subaru?
Repairs may include replacing the radiator fan relay, repairing or replacing damaged wiring or connectors, replacing a blown fuse, or, in rare cases, reprogramming or replacing the ECM.
7. How much does it cost to repair the P1501 code on a Subaru?
Repair costs vary but typically range from $50 to $150 for relay or wiring repairs. ECM replacement or programming can cost significantly more, depending on the model.
8. Can a bad radiator fan cause the P1501 code?
While the fan itself is not the direct cause, a malfunctioning fan can overload the relay circuit, potentially triggering the P1501 code.
9. How can I prevent the P1501 code from returning?
Regularly inspect and maintain the cooling system, including the radiator fan, relays, and wiring, to ensure they remain in good working condition.
10. Will clearing the P1501 code without repairs fix the problem?
Clearing the code without addressing the underlying issue will not fix the problem, and the code is likely to return after a short period of driving.
