What is C0622?

The diagnostic trouble code (DTC) C0622 indicates a malfunction in the Steering Angle Sensor (SAS) circuit. This sensor plays a crucial role in the vehicle's stability control and steering systems by providing the vehicle's computer with the angle of the steering wheel. When the SAS malfunctions, it can lead to various issues such as impaired stability control, difficulty in steering, or even the activation of the vehicle's traction control system. This code is commonly seen in vehicles like the 2011-2016 Chevrolet Silverado, 2013-2018 Dodge Ram, and 2014-2019 Ford F-150. Drivers may notice that the steering feels off, or warning lights may appear on the dashboard. Ignoring this issue can lead to more serious problems, such as increased wear on steering components or compromised vehicle safety. Therefore, understanding and addressing the C0622 code is essential for maintaining optimal vehicle performance and safety.

Symptoms

Common symptoms when C0622 is present:

  • The check engine light may illuminate, indicating a problem with the steering angle sensor.
  • Drivers may experience an unusual steering feel, such as excessive looseness or stiffness, especially during turns.
  • There might be a noticeable decrease in traction control effectiveness, leading to slipping during acceleration.
  • Some vehicles might display the 'Service Stabilitrak' or similar warning messages on the dashboard.
  • In severe cases, the vehicle's steering may lock up temporarily, posing a significant safety risk.

Possible Causes

Most common causes of C0622 (ordered by frequency):

  1. The most common cause of C0622 is a faulty Steering Angle Sensor, which occurs in about 60% of cases due to wear and tear or electrical failure.
  2. Another likely cause involves wiring issues, such as frayed or corroded wires that can interrupt the sensor's signal.
  3. A software glitch in the vehicle's control module can also trigger the C0622 code and can usually be resolved through a software update.
  4. Less common causes include malfunctioning Electronic Control Units (ECUs) that manage the SAS, which can lead to intermittent issues.
  5. In rare cases, physical damage to the steering column or associated components can cause this error, requiring more extensive repairs.
