This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the part of the car that helps cool the air going into the engine. It's like a fan not working to cool down your computer.
The P023A code indicates a malfunction in the electrical circuit that controls the charge air cooler coolant pump. This pump is responsible for circulating coolant to cool the air entering the engine.
The charge air cooler coolant pump is part of the vehicle's forced induction system, which helps increase engine efficiency and performance by cooling the air before it enters the engine. The P023A code is triggered when the Engine Control Module (ECM) detects an open or faulty circuit in the control circuit for this pump.
• Check Engine Light is on
• Reduced engine performance
• Engine overheating
• Faulty charge air cooler coolant pump
• Open or shorted wiring in the pump circuit
• Faulty ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the charge air cooler coolant pump for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the charge air cooler coolant pump if faulty.
• Replace or reprogram the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools
$200 - $600
Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regular maintenance of the cooling system
• Inspect wiring for wear and damage
• Ensure proper coolant levels
Sensor Issue
• Do not ignore the Check Engine Light.
• Regularly service your vehicle to prevent such issues.
• Consult a professional mechanic if unsure.
Repairs may be covered under the vehicle's powertrain warranty if applicable.
This code has been more prevalent in vehicles with turbocharged engines due to the increased complexity of their cooling systems.
Moderate – Addressing this issue promptly can prevent further engine performance problems.
Driving with a malfunctioning cooling system can lead to engine overheating and potential safety hazards.
• Engine at operating temperature
• Vehicle stationary
The charge air cooler coolant pump is typically located near the front of the engine bay, close to the radiator.
Q: Can I drive with a P023A code?
A: It's not recommended to drive for long periods with this code as it can lead to engine overheating.
Q: How can I reset the P023A code?
A: After repairs, you can reset the code using an OBD-II scanner. However, ensure the issue is resolved to prevent the code from returning.
