OBD II Fault Code

  • OBD II P245A

    OBD-II Code Powertrain Control Module (PCM) failure is defined as a Exhaust Gas Recirculation Cooler Bypass Control Circuit/Open

    The EGR valve recirculates exhaust gases back through the engine so that any remaining unburned fuel can be burned. The engine computer (PCM) is programmed to bypass the Exhaust Gas Recirculation (EGR) Cooler under certain driving conditions. The PCM monitors the system to ensure that the bypass valve operates as requested. If the EGR bypass valve fails to operate as requested, code P245A is stored.

    Common Problems That Trigger the P245A Code

    • Damaged EGR cooler assembly
    • EGR cooler bypass valve failure
    • Powertrain Control Module (PCM) failure
