P1951 Code - Radiator Fan 2 Movement Restricted / Jammed
Quick Answer
The P1951 diagnostic trouble code indicates that there is a restriction or jam in the movement of Radiator Fan 2 in the vehicle's cooling system. Common causes include Faulty radiator fan motor: A malfunctioning fan motor can lead to restricted movement or jamming of the radiator fan, Obstruction in the fan blades: Debris, such as leaves or plastic bags, can obstruct the radiator fan blades, preventing them from spinning freely, Electrical issues: Problems with the fan relay, wiring, or control module can also lead to restricted movement of the radiator fan. 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 P1951 Description
The P1951 diagnostic trouble code indicates that there is a restriction or jam in the movement of Radiator Fan 2 in the vehicle's cooling system. The radiator fan plays a crucial role in maintaining the engine's temperature within the optimal range by cooling the radiator. When the fan is restricted or jammed, it can lead to overheating issues, which can have detrimental effects on the engine's performance and longevity.
Common Causes of P1951
- Faulty radiator fan motor: A malfunctioning fan motor can lead to restricted movement or jamming of the radiator fan.
- Obstruction in the fan blades: Debris, such as leaves or plastic bags, can obstruct the radiator fan blades, preventing them from spinning freely.
- Electrical issues: Problems with the fan relay, wiring, or control module can also lead to restricted movement of the radiator fan.
- Mechanical damage: Physical damage to the fan blades or motor can cause movement restrictions.
Symptoms of P1951
- Engine overheating: One of the most common symptoms associated with a restricted or jammed radiator fan is engine overheating. If the fan is unable to cool the radiator effectively, the engine temperature may rise above normal levels.
- Reduced air conditioning performance: The radiator fan also helps cool the air conditioning condenser. If the fan is not functioning correctly, it can impact the performance of the air conditioning system.
- Increased coolant temperature: The temperature gauge on the dashboard may show higher-than-normal coolant temperatures if the radiator fan is not operating properly.
- Engine running hot at idle: The engine may run hotter than usual when the vehicle is idling, as the radiator fan is crucial in dissipating heat during stationary periods.
How to Fix P1951
- Inspect the radiator fan: Check for any visible obstructions or damage to the fan blades or motor.
- Test the fan motor: Use a multimeter to check the continuity of the fan motor to determine if it is faulty.
- Check electrical components: Inspect the fan relay, wiring, and control module for any issues and repair or replace as necessary.
- Clean or replace the fan blades: Remove any debris or obstructions from the fan blades, or replace them if they are damaged beyond repair.
- Test the radiator fan: After completing repairs, test the radiator fan to ensure it is operating correctly.
Cost to Fix P1951
The cost of repairing a restricted or jammed radiator fan can vary depending on the extent of the issue and the specific components that need to be replaced. On average, the repair costs for this issue can range from $200 to $500, including parts and labor. However, it's important to note that labor rates can vary between auto repair shops, with hourly rates typically ranging from $80 to $150. Additionally, the cost of parts and labor may be higher for certain vehicle makes and models, so it's advisable to obtain a specific estimate from a qualified mechanic.
