• Solutions

The P2260 fault code indicates an issue with the Secondary Air Injection System Control B Circuit. This system is designed to reduce emissions by injecting air into the exhaust stream during cold starts, helping to accelerate the catalytic converter's ability to convert harmful emissions into less harmful substances. When the control circuit detects a high voltage problem, this fault code is triggered.

What are the symptoms of the P2260 code?

Symptoms associated with the P2260 code may involve:

• Illuminated check engine light.
• Increased emissions during cold starts.
• Rough idle during initial warm-up.
• Possible failure in emissions testing.
• Unexpected engine performance issues during exhaust operation.

What causes the P2260 code?

Common causes for the P2260 code include:

• Damaged or corroded wiring in the secondary air injection control circuit.
• Faulty secondary air injection valve or pump.
• Malfunctioning electronic control unit (ECU).
• Failed relays or fuses that control the secondary air system.

How to fix P2260?

To resolve the P2260 fault code, follow these steps:

• Inspect the wiring harness and connectors associated with the secondary air injection system for damage or corrosion.
• Test the secondary air injection pump and valve to ensure they operate correctly.
• Check the ECU for any faults and update or replace as necessary.
• Replace blown fuses or faulty relays that may be affecting the system.
