Common causes include a faulty steering angle sensor, wiring issues, or improper installation. Repair costs for replacing the sensor typically range from $150 to $300, while fixing wiring can cost between $100 and $250, depending on the extent of the damage.

Can I drive my car with C0358 or should I stop immediately?

It's best to avoid driving your vehicle until the C0358 code is resolved due to potential safety risks. Ignoring it could lead to loss of steering control, particularly in emergencies or adverse weather.

How can I diagnose C0358 myself using GeekOBD APP?

To diagnose C0358 using the GeekOBD APP, connect the app to your vehicle's OBD2 port, scan for trouble codes, and review the freeze frame data for additional context. Check the sensor's real-time data to look for anomalies in its readings.

What vehicles are most commonly affected by C0358?

DTC C0358 is frequently found in Chevrolet and GMC models, especially those manufactured from 2010 to 2018, such as the Chevrolet Silverado, GMC Sierra, and Chevrolet Equinox.

How can I prevent C0358 from happening again?

To prevent C0358 from reoccurring, schedule regular vehicle maintenance, including inspections of the steering system and electrical connections. Keeping the steering column free of debris and ensuring proper installation of components can also help prevent future issues.

What is C0358?

DTC C0358 indicates a fault related to the steering angle sensor, which is crucial for vehicle stability and steering control. This code is commonly found in various models made by Chevrolet and GMC, particularly those manufactured between 2010 and 2018. When this code is triggered, it signifies that the vehicle's onboard computer has detected a malfunction in the steering angle sensor system. This sensor measures the angle of the steering wheel and is integral to systems like Electronic Stability Control (ESC) and traction control. If the sensor fails or its readings are erratic, it can lead to poor handling characteristics and increased risk of losing control, especially in adverse driving conditions. Drivers may notice symptoms such as the 'Service Stabilitrak' warning light illuminating, reduced effectiveness of traction control, or unusual steering behavior. Ignoring this code can lead to more severe issues, including compromised safety features and potential damage to the vehicle's steering system. It's advisable to address this code promptly to avoid escalating repair costs and ensure safe vehicle operation.

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

Symptoms

Common symptoms when C0358 is present:

  • The dashboard 'Service Stabilitrak' light stays illuminated, indicating a potential issue with the vehicle's stability control system.
  • Drivers may experience erratic steering responses, such as the steering feeling overly loose or tight, affecting overall handling.
  • Fuel economy may decrease by 10-15% due to improper steering assistance and vehicle dynamics.
  • Inconsistent traction control activation may occur, where the system engages unexpectedly, leading to a loss of control in slippery conditions.
  • Unusual noises while turning the steering wheel, potentially indicating mechanical issues within the steering system.

Possible Causes

Most common causes of C0358 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which accounts for about 70% of C0358 cases. This may result from wear, damage, or electrical failure in the sensor.
  2. Another frequent cause is wiring issues, such as frayed or corroded wires, which can disrupt the sensor's signals to the vehicle's computer.
  3. Improper installation of the steering angle sensor during previous repairs can lead to misalignment, triggering the C0358 code. Regular inspections can help prevent this.
  4. Less common but serious causes include a malfunctioning vehicle control module, which can misinterpret sensor data or fail to communicate accurately with other systems.
  5. Rarely, the issue could stem from a physical obstruction or damage to the steering column, affecting sensor operation.
