What is C0307?
DTC C0307 is a diagnostic trouble code that indicates a problem with the vehicle's traction control system, specifically related to the lateral acceleration sensor. This code is particularly prevalent in models such as the 2010-2015 Chevrolet Silverado and GMC Sierra. When the vehicle's computer detects that the lateral acceleration sensor is out of range or malfunctioning, it triggers the C0307 code. This sensor plays a crucial role in helping the vehicle maintain stability, especially during sharp turns or slippery conditions. If the sensor fails, the vehicle may not accurately detect its lateral movement, which can lead to compromised handling and stability, increasing the risk of accidents. Drivers might notice the traction control warning light illuminated on the dashboard. Ignoring this code can lead to further complications, such as additional damage to the stability control system or transmission issues, ultimately leading to costly repairs. Therefore, it is essential to address C0307 promptly to ensure vehicle safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0307 is present:
- Traction control warning light stays illuminated on the dashboard, indicating a system malfunction.
- Vehicle exhibits uneven handling, especially during turns, making it feel unstable or difficult to control.
- Driver experiences sudden loss of traction, such as the wheels spinning excessively during acceleration in wet conditions.
- Increased braking distance, particularly noticeable when attempting to stop on slippery surfaces.
- Inconsistent performance of the stability control system, which may fail to activate when needed.
Possible Causes
Most common causes of C0307 (ordered by frequency):
- The most common cause of C0307 is a faulty lateral acceleration sensor, which can fail due to wear and tear or electrical issues. This accounts for approximately 60% of cases.
- Another common cause is damaged wiring or connectors leading to the sensor, which can result from environmental factors or improper installation during maintenance.
- Corrosion on electrical connections can also lead to intermittent faults, preventing the sensor from sending accurate data to the vehicle's computer.
- Less commonly, a malfunctioning ABS module can cause erroneous sensor readings, leading to C0307 activation and requiring a more in-depth analysis.
- Rarely, software glitches in the vehicle’s control module can generate this code, necessitating a software update or reprogramming.
