What is C0352?

DTC code C0352 indicates a malfunction in the steering position sensor circuit. This issue can arise in various vehicles, particularly in models like the 2015-2018 Chevrolet Malibu and other GM vehicles. The steering position sensor is crucial for providing the engine control module (ECM) with real-time data about the steering wheel's position. This information helps in enhancing the vehicle's handling characteristics and stability control. When the ECM detects a fault in this circuit, it triggers the C0352 code, often accompanied by the illumination of the check engine light. This problem can lead to symptoms such as erratic steering behavior, loss of power steering assist, or even the inability to steer properly, posing potential safety risks while driving. Addressing this issue is essential not only for vehicle performance but also for ensuring the safety of the driver and passengers. The root cause of C0352 can vary, but it often involves wiring issues, sensor malfunctions, or problems with the ECM itself. Ignoring this code can lead to more severe steering problems, making it crucial for car owners to seek diagnosis and repair promptly.

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

Symptoms

Common symptoms when C0352 is present:

  • Check engine light is illuminated and stays on, indicating a fault that needs attention.
  • Steering feels loose or unresponsive, which can lead the driver to struggle with vehicle control, especially during turns.
  • Power steering assist may intermittently fail, making it difficult to steer, particularly at low speeds.
  • Unusual noises when turning the steering wheel, such as grinding or clicking sounds, may indicate a mechanical issue.
  • Increased effort required to turn the steering wheel, leading to driver fatigue over longer journeys.

Possible Causes

Most common causes of C0352 (ordered by frequency):

  1. Faulty steering position sensor - The most common cause, making up about 70% of cases. This sensor can wear out due to age or exposure to harsh conditions.
  2. Wiring issues - Damaged or corroded wiring can disrupt the circuit, causing the sensor to fail. Always inspect the wiring harness for signs of wear.
  3. Faulty ECM - A less common cause, but if the ECM is not interpreting the sensor signals correctly, it can trigger the C0352 code.
  4. Mechanical problems in the steering system - Issues such as worn out bearings or joints can affect sensor performance and lead to inaccurate readings.
  5. Software glitches - Rarely, a software update might be needed to resolve conflicts within the vehicle's computer systems.
