Can steering gear box cause check engine light?

A steering gear box, also known as a steering rack or steering gear, is a mechanical component that is part of the steering system of a vehicle. It is responsible for converting the rotational motion of the steering wheel into the linear motion needed to turn the wheels. A faulty steering gear box can lead to a variety of problems, including:

- Difficulty steering the vehicle

- A knocking or grinding noise when turning the wheel

- Leaking fluid

- Reduced responsiveness of the steering

In some cases, a faulty steering gear box can also cause the check engine light to come on. This is because the steering gear box is connected to the vehicle's electronic control unit (ECU), which monitors various systems and sensors in the vehicle. If the ECU detects a problem with the steering gear box, it may trigger the check engine light to come on.

Therefore, if you notice any of the problems mentioned above, or if the check engine light comes on, it's important to have your vehicle inspected by a qualified mechanic as soon as possible. The mechanic can diagnose the problem and recommend the appropriate repairs.
