What is C0179?
The diagnostic trouble code (DTC) C0179 indicates a fault related to the steering angle sensor. This sensor is crucial for various vehicle systems, especially those associated with stability control and advanced safety features. When this code is triggered, it typically means that the steering angle sensor is malfunctioning, returning incorrect or no data to the vehicle's onboard computer. For drivers, this could manifest as issues with steering responsiveness, triggering warning lights on the dashboard, or even affecting the functionality of systems like traction control and electronic stability control. It’s important to note that this code can be seen in several makes and models, particularly in vehicles from Chevrolet and GMC produced between 2010 and 2018. Ignoring a C0179 code can lead to increased difficulty in steering, potential safety risks, and more costly repairs down the road if the underlying issue isn't addressed promptly. Regular maintenance and early diagnostics are key to preventing the escalation of this issue.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0179 is present:
- The check engine light illuminates and stays lit, indicating a potential issue with the steering system.
- Drivers may experience unresponsive steering or a feeling of looseness, which can make handling the vehicle challenging.
- Fuel economy may decrease by 5-10%, as the vehicle's stability systems are affected, leading to inefficient driving.
- The traction control warning light may also activate, indicating issues with the vehicle's handling systems.
- In some instances, the vehicle may enter limp mode, where power is restricted to prevent further damage.
Possible Causes
Most common causes of C0179 (ordered by frequency):
- The most common cause is a faulty steering angle sensor, which has a likelihood of about 70%. This can be due to wear and tear or electrical issues.
- Another prevalent cause is damaged wiring or connectors related to the sensor, which may result from corrosion or physical damage, accounting for around 20% of cases.
- A third cause could be software issues within the vehicle’s onboard computer, which can sometimes be resolved with a software update or reset.
- Less common but serious is a fault within the vehicle's electronic stability control module, leading to significant safety concerns.
- Rarely, an issue with the steering column itself can cause this code, requiring more extensive repairs.
