What is C034B?

The DTC C034B code indicates a malfunction with the steering angle sensor, a critical component in vehicles such as the 2015-2018 Dodge Charger and Chrysler 300. This sensor monitors the position of the steering wheel, allowing the vehicle's stability control system to make necessary adjustments to enhance safety and handling. When this code appears, it typically signifies that the sensor is transmitting inaccurate data to the vehicle's control module, which can lead to problems like unresponsive steering and compromised traction control. In everyday terms, if your steering feels off or if warning lights illuminate on your dashboard, this could be a sign of a failing steering angle sensor. It’s important to address this issue promptly, as neglecting to do so can lead to reduced vehicle handling capabilities, increased wear on other components, and potentially hazardous driving conditions. The resolution often involves inspecting the sensor connections and wiring, recalibrating the sensor, or replacing it altogether if it's found to be defective. Understanding and addressing the C034B code can ensure a smoother, safer driving experience.

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

Symptoms

Common symptoms when C034B is present:

  • The check engine light may illuminate, indicating a potential issue with the steering angle sensor.
  • Drivers might experience unresponsive steering or difficulty in handling the vehicle, especially during sharp turns.
  • You may notice that the traction control system does not engage properly, leading to potential traction loss in slippery conditions.
  • Erratic behavior of the vehicle's stability control system, with possible activation of the system during normal driving.
  • In some cases, the steering wheel may be misaligned, requiring constant adjustment to maintain a straight path.

Possible Causes

Most common causes of C034B (ordered by frequency):

  1. The most common cause of the C034B code is a faulty steering angle sensor, which has a likelihood of about 60%. This can occur due to wear and tear or exposure to moisture.
  2. Another significant cause could be damaged wiring or poor connections related to the steering angle sensor, typically found in 20% of cases. This is often due to corrosion or physical damage.
  3. A misalignment of the steering angle sensor during installation or after a collision can lead to the C034B code, which accounts for approximately 10% of occurrences. Proper recalibration is essential after any repair.
  4. Less common but serious causes include a malfunction in the vehicle's electronic control unit (ECU), which may be responsible for interpreting signals from the sensor.
  5. Though rare, a software glitch in the vehicle's onboard systems can also trigger the C034B code, requiring a software update or reprogramming to resolve.
