The P2061 fault code indicates an issue with the reductant injection air pump control circuit, which is responsible for injecting reductant fluid into the exhaust stream to reduce emissions. This code signifies that the control circuit is detecting a high signal, suggesting a potential malfunction or electrical issue within the system. Understanding this code is crucial for ensuring the proper function of the vehicle's emission control system.

What are the symptoms of the P2061 code?

The symptoms associated with a P2061 fault code may include:

• Engine warning light illuminated on the dashboard.
• Decreased engine performance or efficiency.
• Increased emissions, potentially leading to a failed emissions test.
• Unusual noises from the reductant pump area.

What causes the P2061 code?

Several factors can trigger the P2061 code, including:

• A malfunctioning reductant injection air pump.
• Faulty wiring or connectors within the control circuit.
• A short circuit or open circuit in the wiring harness.
• Issues with the Vehicle Control Module (VCM) affecting the pump control.
• Low or contaminated reductant fluid in the system.

How to fix P2061?

To resolve the P2061 code, consider the following steps:

• Use an OBD-II scanner to verify the error code and check for other related codes.
• Inspect the wiring and connectors connected to the reductant injection air pump for damage or corrosion.
• Test the functionality of the reductant injection air pump to ensure it is operating correctly.
• Replace any faulty components, such as the pump, wiring, or connectors.
• Clear the code and conduct a test drive to see if the code reappears; if it does, further diagnostics may be required.
