What is C0351?
DTC C0351 refers to a malfunction within the steering angle sensor circuit, which is crucial for various vehicle systems including stability control and traction control. When this code is triggered, it typically indicates an issue with the sensor itself, the wiring leading to the sensor, or the vehicle’s electronic control unit (ECU) that processes the sensor data. The steering angle sensor monitors the position of the steering wheel and sends this information to the ECU to help ensure the vehicle handles correctly during turns and maneuvers. If the sensor is faulty, you may notice issues like erratic steering, poor handling, or the activation of warning lights on your dashboard. Vehicles such as the 2007-2014 Chevrolet Silverado, 2010-2015 Ford Fusion, and 2014-2018 Honda Accord are commonly affected by this code. Ignoring the C0351 code can lead to compromised vehicle safety and performance. It's essential to address any underlying issues promptly to maintain optimal driving conditions and ensure your vehicle responds as expected during critical maneuvers.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0351 is present:
- Check engine light remains illuminated, indicating a persistent issue with the steering angle sensor.
- Steering feels loose or unresponsive, making it difficult to control the vehicle during turns.
- Traction control system warning light activates, suggesting that the vehicle's stability systems may not function correctly.
- Erratic or inconsistent steering behavior that could lead to safety hazards while driving.
- Increased tire wear due to improper alignment caused by faulty steering sensor readings.
Possible Causes
Most common causes of C0351 (ordered by frequency):
- The most common cause of C0351 is a faulty steering angle sensor, which accounts for about 60% of cases. This can occur due to wear and tear or manufacturing defects.
- A second potential cause is damaged wiring or connectors in the sensor circuit, which can result in intermittent or complete loss of signal. This issue may arise from exposure to moisture or road debris.
- Another possible cause is a malfunctioning ECU that fails to interpret sensor data correctly. Regular software updates and maintenance can help prevent this.
- Less common but serious causes include physical damage to the steering column or sensor mount due to accidents or collisions.
- A rare cause could be interference from aftermarket modifications, such as steering wheel replacements that are not compatible with the existing sensor setup.
