This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble reading the temperature of the air that cools the engine. It's like when a thermometer doesn't work right and you can't tell how hot or cold it is outside.
The P00DF code indicates an issue with the range or performance of the charge air cooler coolant temperature sensor. This sensor measures the temperature of the coolant used to cool the air entering the engine.
The charge air cooler coolant temperature sensor monitors the temperature of the coolant that flows through the charge air cooler. This sensor helps the engine control module (ECM) adjust the air-fuel mixture for optimal performance. A range/performance issue means the sensor is not reading within expected parameters.
• Check Engine Light is on
• Poor engine performance
• Increased fuel consumption
• Faulty charge air cooler coolant temperature sensor
• Wiring issues such as shorts or open circuits
• Faulty ECM (Engine Control Module)
Charge Air Cooler: A device used to cool air that has been compressed by a turbocharger or supercharger.
ECM: Engine Control Module, the computer that controls engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the charge air cooler coolant temperature sensor.
• Replace the faulty sensor.
• Repair or replace damaged wiring.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regularly inspect and maintain the cooling system.
• Ensure proper coolant levels.
• Check for leaks or damage in the cooling system.
Sensor Issue
• Address the issue promptly to avoid engine damage.
• Consult a professional mechanic if unsure about repairs.
Check vehicle warranty for coverage on sensors and related components.
This code has been more prevalent in vehicles with turbocharged engines due to the complexity of their cooling systems.
Moderate – Should be addressed soon to prevent potential engine performance issues.
Ignoring this code may lead to increased emissions, which could be against local regulations.
• Engine at operating temperature
• Vehicle stationary
The charge air cooler coolant temperature sensor is typically located near the charge air cooler or intercooler system.
Q: Can I drive with a P00DF code?
A: It's possible to drive short distances, but it's not recommended to ignore the issue as it can affect engine performance.
Q: How do I reset the check engine light after fixing the P00DF code?
A: You can use an OBD-II scanner to clear the code after repairs are completed.

Fitment Required · Vehicle-fitment part
Relevant when coolant-temperature and warm-up faults indicate a thermostat-related issue.
Coolant-temperature and warm-up faults often lead to thermostat testing and replacement.
Thermostats are vehicle-specific and should be matched by engine and housing style.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
