OBD II Fault Code

  • OBD II P023C

OBD-II Code Wiring issue is defined as a Charge Air Cooler Coolant Pump Control Circuit High

The Supercharger has an integrated intercooler (radiator) with its own coolant system to reduce the temperature of the air being forced into the engine. This system uses its own coolant pump that is electronically controlled by the engine computer. If the Coolant Pump fails to operate as requested, code P023C will be stored.

Common Problems That Trigger the P023C Code

  • Charge air cooler coolant pump failure
  • Charge air cooler coolant pump relay failure
  • Wiring issue
