P2061 Code - Reductant Injection Air Pump Control Circuit High
Quick Answer
The P2061 diagnostic trouble code (DTC) refers to the reductant injection air pump control circuit being high. Common causes include Faulty Pump: The reductant injection air pump itself may be faulty and not functioning properly, leading to the high voltage in the control circuit, Wiring Issues: Loose or damaged wiring connections between the pump, control module, and other components can cause voltage spikes in the circuit, Control Module Failure: A malfunctioning control module that regulates the operation of the pump can also trigger this code. 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 P2061 Description
The P2061 diagnostic trouble code (DTC) refers to the reductant injection air pump control circuit being high. This code is typically found in diesel vehicles equipped with a diesel emissions fluid (DEF) system to reduce harmful emissions. The reductant injection air pump is responsible for supplying compressed air to the DEF system, which helps in the conversion of harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor.
Common Causes of P2061
- Faulty Pump: The reductant injection air pump itself may be faulty and not functioning properly, leading to the high voltage in the control circuit.
- Wiring Issues: Loose or damaged wiring connections between the pump, control module, and other components can cause voltage spikes in the circuit.
- Control Module Failure: A malfunctioning control module that regulates the operation of the pump can also trigger this code.
- Corrosion: Corrosion or moisture buildup in the electrical connections can disrupt the flow of voltage in the circuit, causing the high reading.
Symptoms of P2061
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Power: The vehicle may experience a decrease in power output or acceleration due to the inefficient operation of the DEF system.
- Poor Fuel Economy: A malfunctioning reductant injection air pump can lead to decreased fuel efficiency as the engine may not be running at optimal emissions levels.
- Increased Emissions: The vehicle may fail emissions tests or emit higher levels of pollutants due to the ineffective operation of the DEF system.
How to Fix P2061
- Diagnose the Issue: Use a diagnostic scanner to retrieve the fault codes and pinpoint the exact cause of the high voltage in the reductant injection air pump control circuit.
- Inspect Wiring: Thoroughly inspect the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring as needed.
- Test Pump Operation: Test the reductant injection air pump to ensure it is functioning correctly. Replace the pump if it is found to be faulty.
- Check Control Module: Verify the operation of the control module by testing its inputs and outputs. Replace the module if it is determined to be the cause of the issue.
- Clear Codes and Test Drive: Clear the fault codes from the vehicle's computer and take the vehicle for a test drive to ensure that the issue has been resolved.
Cost to Fix P2061
The typical repair costs for addressing a P2061 code can range from $200 to $500, depending on the exact cause of the issue and the cost of parts and labor in your area. It's important to note that these estimates are rough guidelines and can vary significantly based on various factors. Additionally, the specific diagnosis time and labor rates at auto repair shops can vary based on location, vehicle make and model, and engine type. It's recommended to consult local shops for a more accurate estimate of the repair costs.
