What is C0184?

The Diagnostic Trouble Code (DTC) C0184 indicates a malfunction in the steering angle sensor circuit, particularly in models like the 2010-2015 Chevrolet Equinox and GMC Terrain. This sensor plays a crucial role in vehicle stability control systems, providing data that helps control systems like traction control and electronic stability control make informed decisions during critical driving situations. When the C0184 code is triggered, it often means that the steering angle sensor is sending incorrect data to the vehicle's onboard computer. This can be due to issues such as a faulty sensor, damaged wiring, or poor electrical connections. Drivers might experience an illuminated check engine light, and the vehicle may exhibit erratic handling, especially in slippery conditions. In some cases, the vehicle may enter 'limp mode,' limiting its performance to prevent further damage. Addressing this code promptly is essential, as ignoring it can lead to reduced vehicle control and safety hazards on the road. Repairs may include recalibrating the sensor, replacing it, or fixing wiring issues, depending on the underlying cause.

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

Symptoms

Common symptoms when C0184 is present:

  • The check engine light stays on constantly, indicating a persistent issue with the steering angle sensor.
  • Erratic steering behavior may occur, making the vehicle feel unstable, especially during turns or in adverse weather.
  • Drivers may notice a significant delay or lack of response when steering, leading to difficulty in maintaining control.
  • Traction control and stability control systems may not function properly, increasing the risk of skidding or loss of control.
  • A noticeable increase in steering effort may be felt, particularly during parking maneuvers or tight turns.

Possible Causes

Most common causes of C0184 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which accounts for about 60% of C0184 occurrences. This can result from wear and tear over time.
  2. Another frequent reason is damaged wiring or corroded connectors, which can disrupt the sensor's signal to the vehicle’s computer.
  3. Incorrect installation or calibration of the steering angle sensor during previous repairs can also trigger this code. Regular checks during maintenance can prevent this.
  4. Less common but serious issues may involve the power steering control module malfunctioning, which could require significant repairs.
  5. A rare cause could be software glitches in the vehicle's computer system, necessitating a software update to resolve.
