  • OBD II P2429

OBD-II Code Powertrain Control Module (PCM) failure is defined as a Exhaust Gas Temperature Too High

The Exhaust Gas Temperature (EGT) Sensor tells the engine control module (PCM) the temperature of the exhaust gas going into and out of the Selective Catalytic Reduction (SCR). If the PCM detects an implausible signal from the EGT sensor, it will store code P2429.

Common Problems That Trigger the P2429 Code

  • EGR valve failure
  • Exhaust Gas Temperature (EGT) sensor failure
  • Powertrain Control Module (PCM) failure
  • Wiring issue
