This summary uses the existing diagnostic information shown in full below.
This code means that the part of the car's computer that helps keep the engine cool is getting too hot.
The vehicle's internal control module has detected that the temperature of the charge air cooler driver is higher than the specified limit.
The P12FF code indicates that the internal control module, which manages the charge air cooler, has detected an excessively high temperature. This can affect the performance of the engine's cooling system, potentially leading to overheating and reduced efficiency.
• Check Engine Light is on
• Reduced engine performance
• Engine overheating
• Faulty charge air cooler
• Malfunctioning temperature sensor
• Poor electrical connections
Charge Air Cooler: A device used to cool the air compressed by the turbocharger before it enters the engine.
OBD-II: On-Board Diagnostics, a standardized system for self-diagnostics and reporting in vehicles.
• Use an OBD-II scanner to confirm the code.
• Inspect the charge air cooler for damage or blockage.
• Check the temperature sensor and related wiring for faults.
• Replace the faulty charge air cooler.
• Repair or replace the temperature sensor.
• Ensure all electrical connections are secure and corrosion-free.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Ram 1500
• Regular maintenance of the cooling system
• Ensure proper airflow to the charge air cooler
• Check for leaks and blockages periodically
Engine Performance
• Avoid driving the vehicle if it shows signs of overheating.
• Schedule a diagnostic check with a professional mechanic.
Check with the vehicle manufacturer for warranty coverage on engine components.
This code is relatively uncommon and typically associated with vehicles that have high-performance turbocharged engines.
Moderate – Addressing this issue promptly can prevent further engine damage.
Driving with an overheating engine can lead to serious damage and increased emissions.
• Engine at operating temperature
• Vehicle in a controlled environment
The charge air cooler is typically located near the front of the engine bay, connected to the turbocharger system.
Q: Can I drive with a P12FF code?
A: It's not recommended to drive with this code as it can lead to engine overheating.
Q: How do I reset the check engine light after fixing the issue?
A: Use an OBD-II scanner to clear the code after repairs are completed.
