What is C0852?
The diagnostic trouble code C0852 indicates a malfunction in the steering angle sensor circuit. This sensor is critical in vehicles equipped with electronic stability control (ESC) systems. It measures the angle of your steering wheel, providing data to the vehicle's onboard computer to help maintain stability during turns and prevent skidding. When this code is triggered, it often suggests that there may be a fault in the sensor itself, the wiring, or the connections leading to it. Commonly affected vehicles include the 2012-2016 Chevy Malibu and the 2013-2015 Ford Fusion. Drivers may experience issues such as the traction control light activating and potentially a decrease in vehicle handling stability. It's essential to address this issue promptly, as ignoring it can lead to further complications, like additional damage to the steering system or even safety hazards while driving.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0852 is present:
- The check engine light stays on constantly, indicating a persistent issue with the steering system.
- The traction control light illuminates, suggesting problems with stability control and traction management.
- You may notice a delay in steering response, where the vehicle feels unresponsive during turns.
- The steering wheel may feel stiff or lose power assist, making it difficult to control the vehicle.
- In some cases, drivers report that the vehicle feels unstable during cornering, increasing the risk of accidents.
Possible Causes
Most common causes of C0852 (ordered by frequency):
- The most common cause is a faulty steering angle sensor, which accounts for about 70% of cases. This can happen due to wear and tear over time or exposure to moisture.
- A damaged wiring harness is another frequent issue, where frayed wires or loose connections disrupt the signal sent from the sensor to the ECU.
- Incorrect alignment or calibration of the steering angle sensor after repairs can also trigger the C0852 code. It's important to ensure that any steering components are properly aligned during servicing.
- Less common but serious causes include faults in the Electronic Control Unit (ECU) itself, which may require a professional diagnosis and repair.
- A rare cause could be software glitches in the vehicle's system, which might need updates or resets.
