What is C047E?
DTC C047E refers to a malfunction in the steering angle sensor circuit, which is critical for ensuring proper vehicle handling and safety features. This trouble code indicates that the vehicle's onboard diagnostics have detected an issue with the steering angle sensor, which monitors the position of the steering wheel. When this sensor fails or malfunctions, it can lead to various driving issues, including problems with the vehicle's stability control and traction control systems. This can affect how the vehicle responds during turns and can lead to safety hazards if not addressed promptly. Symptoms such as the illumination of warning lights on the dashboard, particularly the traction control or stability control lights, can alert drivers to the problem. Ignoring this code can lead to more severe steering issues over time, potentially leading to costly repairs. For owners of vehicles like the 2016-2020 Ford Explorer and similar models, understanding this code can help in taking timely action to avoid further complications.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C047E is present:
- Check engine light or traction control light stays on constantly, indicating a malfunction in the steering system.
- Vehicle may exhibit erratic steering behavior, with the steering wheel feeling loose or unresponsive during turns.
- Driver may notice the stability control system not functioning properly, increasing the risk of skidding on slippery surfaces.
- Increased wear on tires due to improper alignment as a result of the sensor's failure.
- Possible activation of the anti-lock braking system (ABS) light, suggesting broader braking system issues.
Possible Causes
Most common causes of C047E (ordered by frequency):
- The most common cause of the C047E code is a faulty steering angle sensor, which has a 60% likelihood of being the issue. This sensor can wear out over time or suffer from electrical issues.
- A second common cause is damaged wiring or connectors leading to the steering angle sensor, which can disrupt communication with the vehicle’s computer system.
- Another cause might be software glitches in the vehicle's ECU, which can often be resolved with a software update or reset.
- Less common but serious causes include mechanical issues in the steering column, which could require more extensive repair work.
- A rare cause could be a malfunctioning ABS module that interacts with the steering angle sensor, although this typically presents additional symptoms.
