The P023C fault code on cars refers to an issue with the charge air cooler's (CAC) coolant pump control circuit. This error occurs when the control module detects abnormally high voltage readings in the CAC coolant pump control circuit. This can be caused by a malfunctioning coolant pump or a wiring issue.

The solution to this problem is to diagnose the source of the issue and repair or replace the faulty components as necessary. This can involve testing the voltage of the pump, inspecting the wiring and connections, and cleaning or replacing any corroded parts. It's important to address this issue as soon as possible to prevent further damage to the vehicle's engine and cooling system.

What are the symptoms of the P023C code?

The symptoms of P023C fault code on cars may include:

1. Check Engine Light illumination
2. Overheating engine
3. Loss of power or acceleration
4. Decreased fuel efficiency
5. Cooling fan continues to run even after turning off the engine
6. Air conditioning may not work properly.

What causes the P023C code?

The P023C fault code on cars is caused by a problem in the Charge Air Cooler (CAC) coolant pump control circuit. Specifically, it indicates that the circuit is experiencing a high input or output voltage. This can be caused by a malfunctioning CAC coolant pump relay, a short in the wiring harness, or a faulty coolant pump. The issue can also be caused by a problem with the vehicle's engine control module (ECM) or powertrain control module (PCM). It's important to have the vehicle diagnosed by a qualified mechanic to identify the root cause of the issue and make necessary repairs.

How to fix P023C?

To fix P023C fault code on cars, you can start by checking the charge air cooler coolant pump control circuit and its components. Here are some steps:

1. Check the electrical connections and wiring of the coolant pump control circuit. Look for corroded or damaged wires, loose or disconnected connectors, and any signs of wear or damage.

2. Check the charge air cooler coolant pump itself for signs of damage or failure. You can do this by removing the pump and physically inspecting it for any damage or blockages.

3. Check the charge air cooler coolant level and make sure it is within the specified range. If the coolant level is low, add more coolant as needed.

4. If none of the above steps fix the problem, it may be a faulty sensor or control module. In this case, you may need to take your car to a mechanic to have it diagnosed and repaired.
