What is C051C?

The DTC C051C trouble code indicates an issue with the steering angle sensor circuit, particularly in vehicles equipped with advanced driver-assistance systems (ADAS). This code is prevalent in popular models like the 2015-2018 Honda Accord and other vehicles from manufacturers such as Toyota and Nissan, which also utilize similar sensor technologies. When the C051C code is triggered, it typically means the steering angle sensor is not sending the expected signals to the vehicle's control module. This can lead to various issues including loss of stability control, malfunctioning traction control, and problems with other safety systems. Ignoring this code can lead to compromised handling, making your vehicle less safe to drive. In practical terms, if you're experiencing this code, you might notice your steering feels off, or warning lights on your dashboard might illuminate. The steering angle sensor plays a critical role in ensuring your vehicle responds correctly to driver inputs; thus, addressing this code promptly is essential for maintaining optimal vehicle performance and safety.

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

Symptoms

Common symptoms when C051C is present:

  • The check engine light or stability control warning light is illuminated continuously, indicating a potential issue with the steering system.
  • Drivers may experience an unusual feeling in the steering wheel, such as excessive looseness or binding, which can affect handling and responsiveness.
  • There may be a noticeable decrease in fuel efficiency, as the vehicle's systems attempt to compensate for inaccurate sensor readings.
  • In some cases, the vehicle may enter 'limp mode,' which restricts power to the engine and can limit acceleration.
  • You might notice that the vehicle's traction control system engages more frequently, even in dry conditions, due to erroneous readings from the steering angle sensor.

Possible Causes

Most common causes of C051C (ordered by frequency):

  1. The most common cause of DTC C051C is a faulty steering angle sensor, which is likely in about 60% of cases. This can be due to wear and tear or electrical issues.
  2. Another common cause is a problem with the wiring or connectors associated with the steering angle sensor. Damaged wires or corroded connectors can interfere with signal transmission.
  3. Issues with the vehicle's electronic control unit (ECU) can also trigger this code, though this is less frequent. Regularly updating your vehicle's software can help prevent such occurrences.
  4. A less common but serious cause is a malfunctioning power steering system, which may lead to a complete steering failure if not addressed promptly.
  5. In rare cases, a misalignment in the steering system can trigger the C051C code, especially after an accident or significant impact.
