What is C0780?

The C0780 diagnostic trouble code (DTC) indicates a problem with the power steering system, specifically related to the power steering control module. This code is most commonly seen in vehicles like the 2012-2018 Ford Focus, but it can also affect other makes and models equipped with electronic power steering (EPS) systems. When this code is triggered, it often points to a failure in the communication between the power steering control module and other vehicle systems. This can lead to various issues, including loss of power steering assistance, which can make steering the vehicle much more difficult and potentially dangerous. In simpler terms, it’s like losing the power assist when you turn the steering wheel, making it feel heavy and cumbersome. Ignoring this code can result in further complications, such as increased wear on the steering components or even complete loss of steering control. Therefore, addressing a C0780 code promptly is crucial for maintaining vehicle safety and performance.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0780 is present:

  • The check engine light illuminates on the dashboard, indicating a fault in the power steering system.
  • You may experience heavy steering, especially when turning at low speeds or during parking maneuvers.
  • There could be unusual noises from the power steering pump, such as whining or groaning sounds while steering.
  • You might notice an intermittent loss of power steering assistance, making it feel like you are steering a vehicle without power assist.
  • In some cases, the steering wheel may become stiff and unresponsive, particularly after prolonged driving.

Possible Causes

Most common causes of C0780 (ordered by frequency):

  1. The most common cause of the C0780 code (about 60% of cases) is a faulty power steering control module, which can fail due to electrical issues or internal malfunctions.
  2. Another cause (30%) can be damaged wiring or poor connections in the power steering circuit, often due to wear and tear or exposure to moisture.
  3. A less frequent cause (10%) is low power steering fluid levels, which can lead to air entering the system and affecting performance.
  4. In rare cases, the steering gear itself may have internal damage, which can be a serious issue requiring extensive repairs.
  5. Occasionally, software bugs or calibration issues in the vehicle's computer can trigger the C0780 code, necessitating an update or reset.
