If you’ve encountered the 16864/P0480/001152 Diagnostic Trouble Code (DTC) on your vehicle, it’s important to understand what it means and how to address it. This code typically relates to an issue with the cooling fan control system, which can lead to potential engine overheating and performance issues. In this comprehensive article, we’ll delve deep into the causes, symptoms, and possible solutions for the 16864/P0480/001152 DTC code.

Understanding the 16864/P0480/001152 DTC code

What does the DTC code signify?

The DTC code 16864/P0480/001152 is specific to the cooling fan control circuit in the engine. It indicates that there is a malfunction in this system, which requires attention to prevent potential engine damage. Generally, this code triggers the Check Engine Light (CEL) on the dashboard, alerting the driver to an underlying problem.

Potential causes of the 16864/P0480/001152 DTC code

1. Cooling fan control module failure

A common cause of the 16864/P0480/001152 DTC code is a failure or malfunction in the cooling fan control module. This module is responsible for regulating the cooling fan’s speed based on temperature inputs from various sensors. When it malfunctions, it can result in an inability to control the fan properly and may trigger this specific error code.

2. Faulty cooling fan relay

Another possible cause of the 16864/P0480/001152 DTC code is a faulty cooling fan relay. The relay is an electrical component that controls the power supply to the cooling fan. If the relay fails or becomes stuck, the cooling fan may not receive the necessary power, leading to malfunctions and engine overheating.

3. Wiring or connection issues

In some cases, the DTC code 16864/P0480/001152 can also be triggered by wiring or connection problems within the cooling fan circuit. Issues such as loose connections, damaged wiring, or corrosion can disrupt the proper functioning of the cooling fan control system, causing this error code to appear.

Symptoms of the 16864/P0480/001152 DTC code

When the 16864/P0480/001152 DTC code is present, you might experience the following symptoms:

  1. Check Engine Light: The most apparent symptom is the illumination of the Check Engine Light on your vehicle’s dashboard. This light serves as a warning signal for various potential issues within your vehicle’s systems.
  2. Overheating: If left unresolved, this code can lead to engine overheating. Overheating can cause serious damage to the engine, including blown gaskets, warped cylinder heads, or even complete engine failure.
  3. Reduced performance: A malfunctioning cooling fan control system can adversely affect your vehicle’s performance. You may notice reduced acceleration, stalling, or poor fuel efficiency due to increased strain on the engine.

Diagnosing and solving the 16864/P0480/001152 DTC code

Diagnostic steps:

  1. Visual inspection: Start by visually inspecting the cooling fan control module, relay, and associated wiring for any visible signs of damage or loose connections. Examine the wiring harness and connectors for any signs of corrosion or wear.

  2. Check relay operation: Test the cooling fan relay by using a relay tester or by swapping it with a known working relay. If the relay is faulty, replacing it should resolve the issue.

  3. Verify cooling fan control module: If the relay test was successful, the next step is to verify the cooling fan control module’s functionality. You may need a diagnostic tool to monitor the data provided by the module and ensure it is operating within expected parameters.

  4. Inspect cooling fan motors: If all the above steps yield no results, inspect the cooling fan motors directly. Faulty or seized motors can prevent the cooling fan from operating correctly. Consider testing the motors using an external power source.


  1. Replace the cooling fan control module: If diagnosed as faulty, replacing the cooling fan control module should rectify the issue. Ensure the replacement module is compatible with your vehicle’s make and model.

  2. Fix wiring or connection issues: If any broken or corroded wires or connectors are detected during the visual inspection, repair or replace them as necessary. This might require professional assistance if the wiring is complex.

  3. Replace the cooling fan relay: If the relay is found to be faulty, replace it with a new one. Verify the compatibility with your specific vehicle model to ensure proper functioning.
