What vehicles are most commonly affected by C0927?
This code is frequently reported in vehicles like the 2015-2018 Ford F-150, but it can also appear in various models from Chevrolet, GMC, and Toyota, particularly those equipped with advanced driving aids.
How can I prevent C0927 from happening again?
Regular vehicle maintenance, including checks of the electrical system and steering components, can help prevent issues. Additionally, keeping the battery charged and avoiding harsh driving conditions will extend the life of your sensor.
What is C0927?
DTC C0927 is a diagnostic trouble code that indicates a problem with the steering angle sensor circuit. This code is specifically common in vehicles like the 2015-2018 Ford F-150. When the vehicle's system detects a discrepancy in the steering angle sensor's readings, it triggers this code. The steering angle sensor plays a crucial role in various vehicle systems, including stability control and advanced driver-assistance systems (ADAS). If the sensor is malfunctioning, drivers may notice issues such as erratic steering behavior, unintended lane changes, or problems with traction control. Ignoring this code can lead to more severe steering issues and ultimately compromise vehicle safety. If you see the C0927 code, it’s essential to address it promptly to ensure a safe driving experience.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0927 is present:
- The check engine light illuminates and remains on, indicating a fault in the steering system.
- Drivers may experience inconsistent steering feedback, leading to difficulty in maintaining a straight path.
- Fuel economy may decrease by 10-15% due to compromised vehicle stability systems.
- The vehicle may exhibit signs of pulling to one side when driving straight, which can be alarming for drivers.
- Advanced driver assistance features, such as lane-keeping assistance, may become unresponsive or erratic.
Possible Causes
Most common causes of C0927 (ordered by frequency):
- The most common cause of C0927 is a faulty steering angle sensor, with a likelihood of about 60%. This sensor may have internal failures or lose calibration over time.
- A second common cause is damaged wiring or poor connections in the steering angle sensor circuit, which can occur from wear and tear or exposure to harsh conditions.
- Thirdly, low battery voltage or a weak battery can affect sensor performance. Regular battery checks can help prevent this issue.
- Less commonly, the steering rack may have mechanical issues, which can lead to sensor misalignment and trigger the C0927 code.
- A rare but possible cause includes software malfunctions in the vehicle's electronic control unit (ECU) that may require an update or reprogramming.
