OBD II Fault Code

  • OBD II P007D

OBD-II Code Decreased engine performance is defined as a Charge Air Cooler Temperature Sensor Circuit High

The Charge Air Cooler Temperature Sensors tell the engine control module (PCM) the temperature of the air coming out of the charge air cooler assembly. The Charge Air Cooler Assembly cools the air coming out of the turbocharger before the air goes into the engine. If the PCM detects the temperature of the air coming out of the Charge Air Cooler is abnormally low, the PCM will set code P007D.

Decreased engine performance Symptoms

  • Decreased engine performance
  • DPF regeneration may not occur

Common Problems That Trigger the P007D Code

  • Charge air temperature failure
  • Powertrain Control Module (PCM) failure
  • Wiring issue
