P0947 Code - Hydraulic Pump Relay Circuit Low
Quick Answer
The P0947 diagnostic trouble code refers to a malfunction in the hydraulic pump relay circuit. Common causes include Faulty Wiring: Damaged or corroded wiring in the hydraulic pump relay circuit can prevent the proper voltage from reaching the hydraulic pump, Defective Hydraulic Pump Relay: A malfunctioning hydraulic pump relay can fail to send the necessary signals to the hydraulic pump, resulting in low voltage in the circuit, Malfunctioning Hydraulic Pump: A faulty hydraulic pump can also contribute to a P0947 code, as it may not operate correctly even when the relay is functioning correctly. 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 P0947 Description
The P0947 diagnostic trouble code refers to a malfunction in the hydraulic pump relay circuit. The hydraulic pump relay is responsible for controlling the operation of the hydraulic pump, which is a crucial component in the vehicle's hydraulic system. This system is typically found in vehicles with hydraulic suspension, hydraulic steering, or hydraulic braking systems.
Common Causes of P0947
- Faulty Wiring: Damaged or corroded wiring in the hydraulic pump relay circuit can prevent the proper voltage from reaching the hydraulic pump.
- Defective Hydraulic Pump Relay: A malfunctioning hydraulic pump relay can fail to send the necessary signals to the hydraulic pump, resulting in low voltage in the circuit.
- Malfunctioning Hydraulic Pump: A faulty hydraulic pump can also contribute to a P0947 code, as it may not operate correctly even when the relay is functioning correctly.
- Power Supply Issues: Problems with the vehicle's power supply, such as a weak battery or alternator, can lead to low voltage in the hydraulic pump relay circuit.
Symptoms of P0947
- Illuminated Check Engine Light: The most common symptom of a P0947 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Loss of Hydraulic System Functionality: The vehicle may experience a loss of functionality in the hydraulic system, such as erratic steering, poor braking performance, or issues with the suspension.
- Unusual Noises: The hydraulic system may produce unusual noises, such as whining or groaning, indicating a potential issue with the hydraulic pump.
- Fluid Leaks: A P0947 code may also result in fluid leaks from the hydraulic system components, such as the pump or hoses.
How to Fix P0947
- Diagnose the Issue: Begin by using a diagnostic scanner to retrieve the specific trouble code (P0947) and identify the underlying cause of the problem.
- Inspect Wiring and Connections: Check the wiring and connections in the hydraulic pump relay circuit for any damage, corrosion, or loose connections. Repair or replace any faulty components.
- Test the Hydraulic Pump Relay: Test the hydraulic pump relay to ensure it is functioning correctly. Replace the relay if it is found to be defective.
- Check the Hydraulic Pump: Inspect the hydraulic pump for any signs of damage or malfunction. Test the pump's operation and replace it if necessary.
- Clear the Code: Once the repairs have been completed, clear the diagnostic trouble code from the vehicle's computer using a scanner. Test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0947
The cost of repairing a P0947 code can vary depending on the specific cause of the issue and the vehicle make and model. On average, the cost of parts for this repair can range from $50 to $200, while the labor cost can be between $100 and $300. This brings the total repair cost to approximately $150 to $500. It is important to note that these estimates are rough averages and actual costs may vary based on factors such as location, labor rates, and the extent of the repairs needed. It is advisable to consult with a professional mechanic for a more accurate cost estimate tailored to your specific vehicle.
