Decodificando el Código P0480 de Chevrolet: Causas y Soluciones

Do you know what causes problems in your car? Understanding the diagnostic trouble codes (DTC) that your car’s onboard computer generates is crucial in ensuring the optimal performance of your vehicle. Let’s delve into the specifics of the P0480 DTC and how to address it.

System: Auxiliary emission

The P0480 diagnostic code pertains to the motor cooling fan circuit. During operation, your car’s radiator requires a continuous flow of air to maintain a proper temperature. However, when the vehicle comes to a halt, the airflow is reduced, leading to a rise in temperature. The Powertrain Control Module (PCM) detects this temperature spike via the Coolant Temperature Sensor (CTS) and activates the cooling fan relay to mitigate overheating.

Common Symptoms of the P0480 DTC:

  • The Check Engine light is illuminated.
  • Overheating occurs when the vehicle slows down or is stationary.

Potential Causes of the P0480 DTC:

  • Defective fan control relay.
  • Short circuit in the fan relay wiring system.
  • Malfunctioning cooling fan.
  • Faulty Coolant Temperature Sensor (CTS).
  • Electrical connection issues in the fan’s cooling circuit.
  • Problems with the Intake Air Temperature (IAT) sensor.
  • PCM operational irregularities.

Ways to Address the P0480 DTC:

  • Conduct a visual inspection to ensure the fan and radiator are unobstructed, and check for any signs of fan damage.
  • Inspect the electrical connections of the fan and address any deterioration.
  • Utilize an automotive scanner to clear the DTC from the PCM memory.
