OBD II Fault Code

  • OBD II P2260

    OBD-II Code Powertrain Control Module (PCM) failure is defined as a Secondary Air Injection System Control "B" Circuit High

    The Secondary Air Injection System pumps outside fresh air into the Exhaust System during cold engine start up. This additional air helps burn up the highly rich exhaust emissions that are produced when the engine is warming up. The Secondary Air System typically has an Air Pump and some tubes or plumbing to route the air. The system also has a solenoid and Check Valve(s) to control the airflow. When the engine control module (PCM) detects a faulty with the Secondary Air Injection System, it will set code P2260.

    Common Problems That Trigger the P2260 Code

    • Clogged or disconnected vacuum hose
    • Powertrain Control Module (PCM) failure
    • Secondary air pump failure
    • Secondary air pump relay failure
    • Wiring issue
