What is C04D4?

DTC C04D4 is a diagnostic trouble code that signals a problem related to the vehicle's stability control system. More specifically, it indicates an issue with the steering angle sensor, which is crucial for ensuring that the vehicle maintains proper handling and stability during driving. When this code appears, it often means that the sensor is not providing correct data to the vehicle's onboard computer, potentially leading to issues such as a malfunctioning Electronic Stability Control (ESC) system. This can result in decreased vehicle performance, particularly in slippery conditions where stability control is most needed. Commonly found in vehicles like the 2014-2019 Ford Escape and 2016-2018 Honda CR-V, the C04D4 code may manifest alongside other related codes, complicating the diagnosis. Ignoring this code can lead to unintended consequences, such as compromised safety features that could increase the risk of accidents during adverse driving conditions. Therefore, addressing the C04D4 code promptly is essential for maintaining vehicle safety and performance.

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

Symptoms

Common symptoms when C04D4 is present:

  • The check engine light remains illuminated, signaling a persistent issue that requires diagnosis.
  • The vehicle experiences a noticeable decrease in handling stability, especially during sharp turns or adverse weather conditions.
  • Drivers may notice that the traction control system seems to engage at inappropriate times, leading to an unexpected loss of power.
  • There may be a noticeable increase in difficulty when steering, especially during low-speed maneuvers.
  • In some cases, the steering wheel may be misaligned, leading to uneven tire wear and affecting overall driving comfort.

Possible Causes

Most common causes of C04D4 (ordered by frequency):

  1. The most common cause of a C04D4 code is a faulty steering angle sensor, which has a likelihood of around 60%. This sensor can fail due to wear and tear or damage from an accident.
  2. Another potential cause is damaged wiring or poor connections in the steering angle sensor circuit, which may lead to inaccurate readings transmitted to the vehicle's ECU.
  3. Improper calibration after service work is performed on the steering column can also trigger this code, emphasizing the importance of professional repairs.
  4. Less common, but serious causes include issues with the ABS module, which can affect the overall stability control system.
  5. A rare cause could be a software glitch in the vehicle's ECU that misinterprets normal sensor signals, necessitating an update or reprogramming.
