OBD II Fault Code

  • OBD II P2416

    OBD-II Code Decreased engine performance is defined as a O2 Sensor Signals Swapped Bank 1 Sensor 2/Bank 1 Sensor 3

    The Oxygen Sensors tell the engine control module (PCM) the amount of oxygen left over after the combustion process. each bank (or side) of the motor has its own oxygen sensor. If PCM determines that the wiring harnesses from the sensors have been crossed using a logic based strategy, the PCM will set code P2416.

    Decreased engine performance Symptoms

    • Increased fuel consumption

    Common Problems That Trigger the P2416 Code

    • Oxygen sensor wiring has been misrouted
