You can use the GeekOBD APP to scan for codes and view freeze frame data. This information helps you understand the context of the problem. Look for the C0751 code, check live data from the steering angle sensor, and compare it against expected values.

What vehicles are most commonly affected by C0751?

Vehicles like the 2010-2018 Chevrolet Malibu, 2014-2017 Chevrolet Impala, and various models from GM are frequently affected by this code. Always check for recalls or technical service bulletins regarding the traction control system for your specific model.

How can I prevent C0751 from happening again?

Regular vehicle maintenance, including periodic checks of the steering system and sensor calibrations after wheel alignments, can help prevent C0751 from recurring. Avoiding aftermarket modifications that interfere with the electrical systems also reduces risk.

What is C0751?

DTC C0751 refers to a specific diagnostic trouble code that indicates a problem with the traction control system, particularly related to the steering angle sensor. This code is common in several makes and models, such as the 2010-2018 Chevrolet Malibu and other GM vehicles. The traction control system (TCS) is crucial for enhancing vehicle stability by preventing wheel spin during acceleration. When this code appears, it typically signifies issues with the steering angle sensor's calibration, wiring, or internal failure. Problems can manifest as an illuminated check engine light, and if left unresolved, they may lead to degraded traction control performance or erratic handling characteristics, especially in slippery conditions. It's essential to address DTC C0751 promptly, as it can compromise safety and vehicle handling. Drivers might experience symptoms like the check engine light being on, difficulties with stability control, or even reduced engine power as a precautionary measure by the vehicle’s onboard systems. Regular maintenance, including checking sensor connections and system calibrations, can help prevent the occurrence of this trouble code.

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

Symptoms

Common symptoms when C0751 is present:

  • Check engine light stays on constantly, indicating a persistent fault in the traction control system.
  • Vehicle stability control may feel compromised, with the car swerving or slipping unexpectedly during turns or in inclement weather.
  • Drivers may notice a reduction in engine power, as the vehicle's onboard computer limits performance to maintain traction and safety.
  • Unusual noises or vibrations can occur while making sharp turns, hinting at underlying traction control issues.
  • The traction control light may intermittently illuminate, signaling that the system is engaging or malfunctioning.

Possible Causes

Most common causes of C0751 (ordered by frequency):

  1. The most common cause of DTC C0751 is a faulty steering angle sensor, which has an approximately 60% likelihood of being the culprit. This sensor can fail due to wear and tear or electrical issues.
  2. Another cause may be damaged wiring or poor connections, accounting for about 25% of cases. Corrosion or frayed wires can disrupt the sensor's signals.
  3. Improper calibration after a wheel alignment or steering component replacement can also trigger this code, especially if the vehicle has recently undergone maintenance.
  4. Less common but serious causes include faults in the traction control module itself, which could lead to a complete failure of the traction control system.
  5. A rare cause could be interference from aftermarket modifications or devices that affect the vehicle's electrical systems, which can result in unexpected fault codes.
