What is C0237?
The DTC code C0237 indicates a problem with the steering angle sensor calibration. This sensor is crucial for stability control and anti-lock braking systems in modern vehicles. When the sensor is out of calibration, it can lead to erratic steering behavior, reduced traction control, and potential safety hazards. This issue is commonly found in vehicles like the 2012-2015 Chevrolet Malibu and the 2010-2013 Ford Fusion. Drivers may notice symptoms such as the 'Check Engine' light illuminating, or the vehicle may exhibit unusual steering responses, particularly during cornering or when driving on uneven surfaces. In more severe cases, this malfunction can compromise vehicle handling, making it crucial to address promptly. Ignoring the C0237 code can lead to further complications, such as increased wear on steering components or even loss of vehicle control. It's advisable to perform a thorough diagnostic check using tools like the GeekOBD APP to retrieve additional trouble codes that may provide more context about the issue.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0237 is present:
- Check engine light stays on constantly, indicating a persistent issue that needs to be diagnosed.
- Steering feels loose or inconsistent, leading to a lack of confidence during driving and potential safety risks.
- Vehicle stability control features may not activate correctly, compromising handling during adverse conditions.
- Unusual noises from the steering column, such as grinding or clicking, which could indicate mechanical issues.
- Difficulty in making sharp turns or turning the steering wheel, leading to driver frustration and potential accidents.
Possible Causes
Most common causes of C0237 (ordered by frequency):
- Incorrect calibration of the steering angle sensor, which can occur after repairs or replacements. This is the most common cause, with a likelihood of 60%.
- Wiring issues, such as damaged or corroded connectors, affecting communication between the sensor and the vehicle's computer system.
- Faulty steering angle sensor itself, which may fail due to wear or manufacturing defects. Regular checks can help prevent this.
- ECU software glitches or updates that may need to be performed to ensure the system operates correctly.
- Less commonly, issues with the vehicle's power steering system can also lead to erroneous readings from the sensor.
