What is C0772?

The diagnostic trouble code (DTC) C0772 signifies a problem with the Steering Wheel Position Sensor Circuit. This code is particularly common in various General Motors vehicles, including models like the Chevrolet Malibu (2016-2020) and GMC Terrain (2017-2021). The Steering Wheel Position Sensor is essential for ensuring the vehicle's electronic stability control and traction control systems operate correctly. When this sensor malfunctions or provides inconsistent readings, it can result in a range of performance issues. Symptoms may include erratic steering behavior, difficulty in handling, or warning lights illuminating on the dashboard. The steering system relies heavily on accurate feedback from this sensor. If the code is triggered, it indicates that the sensor's output is outside the expected range, which could be due to wiring issues, a faulty sensor, or other electronic malfunctions. Ignoring this code can lead to steering instability or poor vehicle handling, making it critical for vehicle owners to address the issue promptly. Regular maintenance and checks can help prevent this code from appearing, but if it does, understanding the underlying cause will be key to an effective resolution.

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

Symptoms

Common symptoms when C0772 is present:

  • The steering wheel may feel loose or unresponsive while driving, leading to difficulty in controlling the vehicle.
  • The check engine or stability control warning light may stay illuminated, indicating a fault in the steering system.
  • Drivers may experience inconsistent steering feedback, making it hard to maintain a straight line on the road.
  • In severe cases, the vehicle may exhibit sudden changes in steering direction, posing a safety risk.
  • Fuel consumption may increase due to the vehicle's stability control system working harder to compensate for erratic behavior.

Possible Causes

Most common causes of C0772 (ordered by frequency):

  1. The most common cause of DTC C0772 is a faulty Steering Wheel Position Sensor, with a likelihood of around 60%. This sensor can wear out or fail due to electrical issues.
  2. Another potential cause is damaged wiring or poor connections within the steering column, which can lead to erratic sensor readings.
  3. In some cases, dirt or debris can interfere with the sensor's operation, highlighting the importance of regular maintenance to keep the steering system clean.
  4. Less commonly, issues with the vehicle's Body Control Module (BCM) can cause this code to trigger, indicating a possible electronic fault.
  5. A rare but serious cause could be a malfunction in the Electronic Power Steering (EPS) system, which may require extensive diagnostics and repairs.
