What is C0753?

The diagnostic trouble code (DTC) C0753 indicates a problem with the steering position sensor circuit. This sensor is responsible for detecting the position of the steering wheel and relaying that information to the vehicle's electronic control unit (ECU). When the C0753 code is triggered, it typically signifies that the signal from the steering position sensor is out of range or missing altogether. This issue can impact various vehicle systems, including electronic stability control and power steering. In practical terms, if you experience this code, you may notice a lack of responsiveness in your steering, or the vehicle may feel unstable during turns. Ignoring this DTC can lead to further complications such as steering failure, which can compromise your safety on the road. For many drivers, especially those using affected models such as the 2014-2018 Chevrolet Silverado or GMC Sierra, addressing this code promptly is crucial for maintaining optimal vehicle performance and safety.

Symptoms

Common symptoms when C0753 is present:

  • Check engine light remains illuminated, indicating an issue with the steering sensor.
  • Steering responsiveness decreases, making it feel heavier or less precise during driving.
  • Power steering assist may fail intermittently, leading to difficulty maneuvering the vehicle.
  • Stability control warning lights activate, potentially impacting vehicle handling.
  • Increased fuel consumption may occur due to the ECU adjusting parameters to compensate for the sensor fault.

Possible Causes

Most common causes of C0753 (ordered by frequency):

  1. The most common cause is a faulty steering position sensor, which occurs in about 60% of cases. This can be due to wear and tear or manufacturing defects.
  2. Wiring issues such as frayed or corroded wires can lead to signal loss, accounting for roughly 25% of C0753 occurrences. Regular inspections can help prevent this.
  3. Poor connections at the sensor or ECU can cause intermittent faults, making up about 10% of cases. Ensuring secure connections can prevent these issues.
  4. Less common causes include ECU malfunctions, which can lead to misinterpretation of signals and require a more in-depth diagnosis.
  5. In rare cases, software issues within the vehicle's control module can trigger this code, necessitating a software update or reprogramming.
