The most common cause of C0345 is a faulty steering angle sensor, which can be replaced for $150 to $300. Other causes include misalignment and electrical issues, which may also require additional costs for realignment or repairs.
Can I drive my car with C0345 or should I stop immediately?
It's best to avoid driving your vehicle if the C0345 code is present, as it can compromise your safety by affecting steering response and stability. If you must drive, do so cautiously and seek repairs as soon as possible.
How can I diagnose C0345 myself using GeekOBD APP?
To diagnose C0345 using the GeekOBD APP, first connect the device to your vehicle’s OBD2 port. Use the app to scan for codes and view freeze frame data, which can help identify the context of the issue. Follow the app's diagnostic suggestions and check the sensor's readings to pinpoint the fault.
What vehicles are most commonly affected by C0345?
C0345 is commonly found in vehicles like the 2013-2018 Ford Fusion, 2015-2018 Lincoln MKZ, and various models from Chevrolet and GMC. Be sure to check for any recalls or Technical Service Bulletins (TSBs) related to this issue.
How can I prevent C0345 from happening again?
To prevent C0345 from recurring, ensure regular maintenance checks for your steering system, especially after any suspension work or accidents. Additionally, keep an eye on warning lights and have your vehicle inspected if you notice any changes in steering response.
What is C0345?
The Diagnostic Trouble Code (DTC) C0345 indicates a malfunction in the steering angle sensor, a crucial component for vehicle stability control systems. This sensor monitors the position of the steering wheel and helps the vehicle's computer determine how much steering input is being applied. When the C0345 code is triggered, it often means that the sensor is malfunctioning or has become misaligned, leading to potential issues with traction control and electronic stability control. If the steering angle sensor fails, you may notice symptoms like the 'Check Engine' light illuminating on your dashboard, erratic behavior from the traction control system, or even unresponsive steering under certain conditions. In practical terms, driving with this code can lead to compromised vehicle handling and safety, making it essential to address this issue promptly. Vehicle makes like the Ford Fusion from 2013 to 2018, as well as models like the Lincoln MKZ and various Chevrolet and GMC vehicles, are commonly affected by this code. Ignoring this malfunction can result in further complications, including increased wear on other steering components and potential safety risks while driving.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0345 is present:
- Check engine light stays on constantly, indicating a fault in the steering angle sensor system.
- Traction control warning light may illuminate intermittently, affecting driving safety.
- Steering feels loose or unresponsive, especially during sharp turns or at high speeds.
- Inconsistent feedback from the steering wheel, making it difficult to maintain a straight path.
- Increased tire wear due to misalignment that might not be addressed without fixing the sensor.
Possible Causes
Most common causes of C0345 (ordered by frequency):
- The most common cause is a faulty steering angle sensor, which accounts for about 70% of C0345 cases. This sensor can wear out over time or become damaged due to external impacts.
- Another possible cause is misalignment of the steering angle sensor, which can occur during routine maintenance or due to suspension work. Regular checks after alignment services can help prevent this.
- Electrical issues, such as damaged wiring or poor connections to the sensor, can also trigger this code. Ensuring proper connections and inspecting wiring can help prevent future occurrences.
- Less common but serious causes include a malfunctioning Electronic Control Unit (ECU), which may require replacement or reprogramming to resolve the issue.
- A rare cause could be software glitches in the vehicle's system, which may require a software update to fix.
