Can I drive my car with C0573 or should I stop immediately?
It is not advisable to drive your vehicle with the C0573 code active. Doing so may compromise vehicle handling and safety. If you notice symptoms such as erratic steering or warning lights, have the vehicle inspected as soon as possible.
How can I diagnose C0573 myself using GeekOBD APP?
To diagnose C0573 using the GeekOBD APP, connect the device to your OBD2 port, run a diagnostic scan to retrieve the code, and check for any freeze frame data that provides context. Look for patterns in the symptoms and note any additional codes that may appear.
What vehicles are most commonly affected by C0573?
DTC C0573 is commonly found in various GM vehicles, particularly models like the Chevrolet Silverado (2014-2020) and GMC Sierra (2014-2020). These vehicles often experience issues related to the steering angle sensor, and it's important to check for recalls or technical service bulletins (TSBs) related to this code.
How can I prevent C0573 from happening again?
Regular maintenance, including checking the wiring and electrical connections related to the steering system, can help prevent C0573. Ensuring that any steering components are not damaged during service can also mitigate risks. Additionally, using the GeekOBD APP for periodic diagnostics can alert you to potential issues early.
What is C0573?
DTC C0573 indicates a malfunction within the steering angle sensor system, specifically related to the sensor's performance or communication with the vehicle's control modules. This code typically appears in various General Motors (GM) vehicles, including popular models like the Chevrolet Silverado (2014-2020) and GMC Sierra (2014-2020). The steering angle sensor is crucial for determining the position of the steering wheel, an essential component for stability control, traction control, and advanced driver-assistance systems (ADAS). When this sensor fails or sends faulty signals, it can lead to impaired vehicle handling and increased risk of accidents. Drivers may experience symptoms like the illumination of the check engine light, erratic steering behavior, or issues with electronic stability control. Ignoring this code could result in further damage to the steering system, costly repairs, and a potential safety hazard. Addressing the C0573 code promptly is essential for maintaining vehicle safety and performance. Regular diagnostic checks can help catch these issues early on, preventing complications down the road.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0573 is present:
- The check engine light illuminates, often remaining on consistently, which is a common indicator of a malfunctioning sensor.
- Drivers may notice erratic steering response, making it difficult to maintain a straight path, especially during turns or lane changes.
- Fuel economy may decrease due to the vehicle's stability control system compensating for the faulty sensor, with potential drops of 5-10%.
- You might experience warning messages related to the stability control system on the dashboard, alerting you to the issue.
- In severe cases, the steering wheel may feel unusually loose or tight, indicating a need for immediate mechanical inspection.
Possible Causes
Most common causes of C0573 (ordered by frequency):
- The most common cause of the C0573 code is a defective steering angle sensor, with a likelihood of around 60%. This can result from wear and tear or electrical issues in the sensor.
- Another frequent cause can be a poor connection in the wiring harness or corrosion at the connectors, leading to communication failures between the sensor and the control module.
- Mechanical damage to the steering column or related components can also trigger this code, especially after accidents or rough terrain driving.
- Less commonly, a malfunction in the power steering control module may result in this code, indicating more complex electronic issues.
- A rare cause could be a software glitch in the vehicle's control module, which might require a software update or reprogramming to resolve.
