Code B2995 Description
The B2995 diagnostic trouble code (DTC) relates to the Auxiliary Electric Water Pump Circuit in a vehicle. This code indicates a problem with the electric water pump that assists in circulating coolant through the engine and maintaining optimal operating temperatures. The auxiliary electric water pump is responsible for providing additional coolant flow when needed, such as during engine warm-up or when the vehicle is stationary but the engine is running.
Common Causes of B2995
- Faulty electric water pump: The most common cause of this code is a malfunctioning electric water pump that is not circulating coolant properly.
- Electrical issues: Wiring harness problems, loose connections, or blown fuses related to the auxiliary electric water pump circuit can trigger this code.
- Coolant leaks: Leaking coolant can affect the performance of the electric water pump and lead to this code being set.
- Thermostat issues: A faulty thermostat can disrupt the coolant flow and cause the auxiliary electric water pump to work harder, potentially triggering the code.
- Cooling system blockages: Blockages in the cooling system, such as a clogged radiator or hoses, can impede coolant circulation and affect the electric water pump's operation.
Symptoms of B2995
- Engine overheating: One of the most common symptoms associated with this code is engine overheating due to inadequate coolant circulation.
- Low coolant warning light: The vehicle's dashboard may display a warning light indicating low coolant levels, even if the reservoir is filled.
- Poor heater performance: The cabin heater may not produce sufficient heat if the auxiliary electric water pump is not functioning correctly.
- Engine misfires: In some cases, a malfunctioning electric water pump can lead to engine misfires or rough idling.
- Check engine light: The check engine light may illuminate on the dashboard, signaling a problem with the auxiliary electric water pump circuit.
How to Fix B2995
- Diagnose the issue: Use a scan tool to retrieve the DTC and perform a visual inspection of the electric water pump, wiring, and connections.
- Test the electric water pump: Check the operation of the electric water pump by applying power directly to it to see if it functions correctly.
- Replace the electric water pump: If the pump is found to be faulty, replace it with a new unit following the manufacturer's guidelines.
- Inspect and repair wiring: Check the wiring harness for any damage or corrosion, repair or replace as necessary to ensure proper electrical connections.
- Refill coolant and bleed the system: After completing the repair, refill the coolant system with the appropriate coolant mixture and bleed out any air pockets to ensure proper circulation.
Cost to Fix B2995
The cost of repairing the Auxiliary Electric Water Pump Circuit can vary depending on the make and model of the vehicle, the location of the repair shop, and the extent of the damage. On average, the parts for this repair can range from $100 to $300, while the labor costs can range from $150 to $400. Overall, the total cost of addressing this issue can be between $250 and $700. It is recommended to consult with a qualified mechanic or repair shop to get an accurate estimate based on your specific vehicle and location.
