OBD II Fault Code

  • OBD II P2444

OBD-II Code Powertrain Control Module (PCM) failure is defined as a Secondary Air Injection System Pump Stuck On

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 Pump is controlled by the engine computer. If the pump does not operate as requested, code P2444 will be set.

Common Problems That Trigger the P2444 Code

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