Using the GeekOBD APP, you can scan for DTCs, view live data from the steering angle sensor, and check for any additional codes that may provide clues about the issue. Follow the app's step-by-step guide for detailed diagnostics.
What vehicles are most commonly affected by C0850?
C0850 is often found in vehicles like the 2013-2017 Ford Fusion and the 2014-2016 Chevrolet Malibu. Always check for recalls or Technical Service Bulletins (TSBs) related to the steering system for these models.
How can I prevent C0850 from happening again?
To prevent C0850, ensure regular vehicle maintenance, avoid rough driving conditions, and periodically inspect the steering system for any damage or wear. Keeping the vehicle's software updated can also help.
What is C0850?
The diagnostic trouble code (DTC) C0850 indicates a malfunction in the steering angle sensor circuit. This sensor is crucial for various vehicle systems, including stability control, traction control, and advanced driver assistance systems (ADAS). When the C0850 code is triggered, it typically means there's an issue with the sensor's alignment, calibration, or electrical connections. For many car owners, this code can manifest in several ways, such as the illumination of the warning lights on the dashboard, particularly the traction control or stability control lights. The steering angle sensor helps the vehicle understand the driver's steering input and adjusts the vehicle's handling accordingly. If this sensor is malfunctioning, it can lead to poor handling characteristics and reduced vehicle stability, especially during adverse weather conditions. Commonly affected vehicles include the 2013-2017 Ford Fusion and the 2014-2016 Chevrolet Malibu. Ignoring this code can result in compromised safety features and increased repair costs down the line, so addressing it promptly is crucial.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0850 is present:
- The check engine light or traction control light is illuminated, indicating a problem with the steering system.
- Unusual steering behavior, such as the steering wheel feeling loose or unresponsive, which can lead to difficulties in handling.
- Increased wear on tires due to improper alignment caused by a faulty steering angle sensor.
- The vehicle may exhibit stability control issues, such as unexpected braking or swerving during turns.
- The steering angle sensor calibration warning may appear on the dashboard, indicating a need for recalibration.
Possible Causes
Most common causes of C0850 (ordered by frequency):
- The most common cause of C0850 is a misaligned or damaged steering angle sensor, which accounts for about 60% of cases. This can occur due to accidents or rough driving conditions.
- Another cause can be poor electrical connections or damaged wiring in the sensor circuit, often leading to intermittent issues. This may involve corroded connectors or frayed wires.
- A third cause might include software malfunctions in the vehicle's control module, which can sometimes be resolved with a simple software update.
- Less common but serious causes include a failing steering column assembly that requires replacement, posing a safety risk.
- A rare cause could be a malfunctioning Electronic Control Unit (ECU) that may require extensive testing and diagnostic efforts.
