What is C0C02?

The C0C02 diagnostic trouble code (DTC) is a trouble code that indicates a problem related to the vehicle's power steering system, particularly in certain Ford models including the 2015-2020 Ford F-150. This code specifically points to a fault in the steering angle sensor, which is crucial for ensuring accurate steering responsiveness and stability control. When the steering angle sensor malfunctions, it can lead to erratic steering behavior, increased difficulty while maneuvering, and an illuminated dashboard warning light. In practical terms, this means that drivers may experience a sudden loss of power steering assistance or find that their vehicle does not respond as expected during turns. It's essential to address this issue promptly, as ignoring it can lead to more severe handling problems and potentially compromise vehicle safety. Moreover, frequent steering issues might indicate underlying wiring problems or sensor failures, making it crucial for drivers to seek a thorough diagnosis from a qualified technician. Understanding and resolving the C0C02 code is vital for maintaining vehicle operability, especially for drivers who rely on their vehicles for daily commuting or towing applications.

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

Symptoms

Common symptoms when C0C02 is present:

  • The check engine light remains illuminated, indicating a persistent issue that needs immediate attention.
  • Drivers may notice that the vehicle feels harder to steer, particularly at lower speeds, leading to difficulty in parking or maneuvering.
  • A decrease in fuel efficiency may be observed, with reports of 10-15% reduction in mileage due to the increased strain on the engine from steering system failures.
  • Unusual noises from the steering column, such as grinding or whining sounds, may indicate a failing power steering pump or related components.
  • The steering may feel unresponsive or delayed, especially during sharp turns, which can be alarming for drivers.

Possible Causes

Most common causes of C0C02 (ordered by frequency):

  1. The most common cause of the C0C02 code is a faulty steering angle sensor, with a likelihood of 60%. This sensor sends crucial data to the vehicle's stability control system.
  2. Wiring issues, such as damaged or corroded connectors, can also cause this error code, affecting the sensor's ability to transmit accurate readings.
  3. Incorrect steering wheel alignment might lead to sensor miscalibration, causing the C0C02 code to trigger. Regular maintenance can help prevent this issue.
  4. Less common causes might include software glitches in the vehicle's electronic control unit (ECU), which can usually be resolved with a software update.
  5. In rare cases, a complete failure of the power steering system components, such as the pump or rack and pinion, may contribute to this code.
