This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer found a problem with how the engine's coolant temperature and the fuel temperature are related. It's like the car is saying, 'Hey, these two temperatures don't match up like they should!'
The engine control module (ECM) monitors the engine coolant temperature and fuel temperature to ensure they correlate correctly. If the temperatures are not within expected ranges, the ECM triggers this code.
The P008F code is triggered when the ECM detects an inconsistency between the engine coolant temperature sensor readings and the fuel temperature sensor readings. The ECM expects these temperatures to correlate under certain operating conditions. If the correlation is outside the expected range, it sets this code.
• Check Engine Light illuminated
• Poor fuel economy
• Engine overheating
• Engine performance issues
• Faulty engine coolant temperature sensor
• Faulty fuel temperature sensor
• Wiring issues or poor electrical connections
• ECM software issue
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, second generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for both sensors.
• Test the engine coolant temperature sensor.
• Test the fuel temperature sensor.
• Replace the engine coolant temperature sensor.
• Replace the fuel temperature sensor.
• Repair or replace damaged wiring or connectors.
• Update ECM software if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly check and maintain coolant levels.
• Perform routine inspections of engine sensors.
• Ensure proper electrical connections.
Sensor Issue
• Have the vehicle inspected by a professional if the Check Engine Light is on.
• Avoid driving the vehicle if it shows signs of overheating.
Check with the vehicle manufacturer for warranty coverage on sensors.
This code has been observed in vehicles with aging sensors or wiring issues.
Moderate – It should be addressed soon to prevent potential engine damage.
Ignoring this code can lead to engine performance issues and potential safety hazards.
• Engine at operating temperature
• Vehicle in a controlled environment
The engine coolant temperature sensor is typically located near the thermostat housing, while the fuel temperature sensor is usually found on the fuel rail.
Q: Can I drive with a P008F code?
A: It's not recommended to drive for extended periods with this code, as it may lead to engine performance issues.
Q: How do I reset the P008F code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is resolved, it should not return.

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.
