P023B OBD-II: Charge Air Cooler Coolant Pump Control Circuit Low
P023B Severity
Will P023B go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P023B?
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 P023B will be stored.
