What is C0A75?
DTC C0A75 is a diagnostic trouble code that indicates a problem with the vehicle's power steering system, specifically related to the electric power steering (EPS) assist. This code is commonly seen in vehicles like the 2017-2020 Ford F-150 and Explorer, where it signifies that the steering assist is either insufficient or has completely failed. When this code triggers, it can lead to a loss of steering control, making it difficult for the driver to maneuver the vehicle safely. The underlying issue might be caused by a faulty power steering control module, wiring issues, or a malfunctioning sensor that monitors steering input. In practical terms, if you see the C0A75 code, it is essential to address it promptly. Ignoring this issue can result in increased wear on the steering components and may lead to a total loss of steering assist, posing a significant safety risk on the road. Additionally, the check engine light may illuminate, and you might experience symptoms such as heavy steering effort or steering wheel vibration. Overall, while the C0A75 code may seem like a minor annoyance, it requires immediate attention to ensure safe driving conditions.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0A75 is present:
- The check engine light illuminates and stays on, indicating a fault in the steering system.
- Drivers may experience heavy steering effort, particularly at low speeds, making it difficult to turn.
- Steering wheel vibration can occur, especially when driving over bumps or uneven surfaces.
- Unusual noises may be heard from the steering column when turning the wheel.
- There may be a delayed response in steering input, causing the vehicle to lag when changing direction.
Possible Causes
Most common causes of C0A75 (ordered by frequency):
- The most common cause of DTC C0A75 is a faulty power steering control module, with a likelihood of around 40%. This module controls the electric motor that assists in steering, and if it fails, the assist can be lost.
- A second cause could be damaged wiring or poor connections, which can disrupt the communication between the EPS system components. This issue has a likelihood of about 30% and can often be identified through visual inspection.
- Another potential cause is a malfunctioning steering angle sensor, which can result in incorrect input being sent to the power steering system. This has a 20% likelihood and can often be checked with a multimeter.
- Less common but serious causes include issues with the vehicle's battery or charging system, which can affect the power supply to the EPS. This scenario might occur in older vehicles or those with significant electrical issues.
- A rare cause could be software issues within the vehicle's control module, which may require a software update from a dealership to resolve.
