This summary uses the existing diagnostic information shown in full below.
This code means that the car's cooling fan, which helps keep the engine from getting too hot, isn't working right at its second speed level.
The P14FB code indicates a malfunction in the vehicle's cooling fan system, specifically at the second stage of its operation.
The cooling fan system in a vehicle is designed to operate at multiple speeds to efficiently manage engine temperature. The P14FB code is triggered when the Engine Control Module (ECM) detects a problem with the fan's operation at stage 2, which could be due to electrical issues, mechanical failure, or communication errors.

Check with the vehicle manufacturer for warranty coverage on cooling system components.
This code has been associated with cooling fan issues in various models, often due to electrical failures or wear over time.
High – This issue can lead to engine overheating and potential damage if not addressed promptly.
Operating a vehicle with an overheating engine can be dangerous and may lead to further damage or accidents.
• Engine at operating temperature
• Vehicle stationary with the engine running
The cooling fan is typically located at the front of the engine bay, behind the radiator.
Q: Can I drive with a P14FB code?
A: It's not recommended to drive with this code active, as it can lead to engine overheating.
Q: How do I reset the P14FB code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
