Perform a scan to retrieve the codes, and check for any additional faults that may be present. Use the live data feature to monitor the steering angle sensor readings and look for any inconsistencies.
What vehicles are most commonly affected by C0134?
The C0134 code is commonly found in Ford vehicles from 2013 to 2018, including the Ford Fusion and Ford Escape, as well as Chevrolet models like the Malibu and Equinox during the same production years.
How can I prevent C0134 from happening again?
To prevent the C0134 code from recurring, ensure regular maintenance of your vehicle, particularly around the steering and suspension systems. Keeping the wiring and connectors clean and free of corrosion can also help, as can addressing any leaks of fluid that might impact the steering system.
What is C0134?
The DTC C0134 code is a diagnostic trouble code that indicates an issue with the stability control system, specifically pointing to a malfunction in the steering angle sensor or its circuit. This problem can arise in various vehicles, including popular models from Ford and Chevrolet, particularly those manufactured between 2013 and 2018. When this code is triggered, it typically means that the vehicle's stability control system is not functioning correctly, which can compromise your vehicle's safety features, especially during slippery conditions or emergency maneuvers. The steering angle sensor is crucial for determining the vehicle’s steering angle, which helps the stability control system to apply braking force to individual wheels when needed, ensuring better traction and control. If you’re experiencing this code, you may notice that your ABS light or traction control light stays illuminated on your dashboard. Ignoring this issue can lead to further complications, such as reduced vehicle handling and stability, putting you and your passengers at risk. Addressing the C0134 code promptly is essential for maintaining your vehicle's performance and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0134 is present:
- The ABS light and traction control light remain on, indicating a problem with the vehicle's stability system.
- You may notice that the vehicle feels unstable when turning, especially on wet or slippery roads.
- The steering wheel may feel unresponsive or require excessive effort to turn, indicating potential issues with the steering sensor.
- In some cases, you might experience an unexpected loss of traction during acceleration, leading to wheel slip.
- Your vehicle may exhibit erratic behavior, such as pulling to one side when driving straight.
Possible Causes
Most common causes of C0134 (ordered by frequency):
- The most common cause of the C0134 code is a faulty steering angle sensor, which can occur in about 70% of cases. This sensor can wear out or fail over time due to exposure to moisture or dirt.
- Another potential cause is a damaged wiring harness or poor connections in the steering angle sensor circuit. This can lead to intermittent signals being sent to the vehicle's computer system.
- A third cause could be an issue with the vehicle's ABS module, which processes input from the steering angle sensor. If the module fails, it can trigger the C0134 code.
- Less commonly, the issue may stem from a faulty power steering system, which can affect the performance of the steering angle sensor.
- In rare cases, software glitches in the vehicle’s onboard computer can cause false readings, resulting in a C0134 code.
