Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid pump, multimeter.
Ensure the vehicle is on a level surface and the engine is off. Disconnect the battery for safety.

2. Addressing Check Engine Light

Connect the OBD-II scanner to the vehicle's diagnostic port and retrieve error codes.
Document the error codes and look up their meanings.
Clear the codes and monitor if they return after a short drive.
If a code related to a specific sensor or system is present, replace that component as needed (e.g., oxygen sensor, mass airflow sensor).

3. Power Steering Inspection and Repair

Check the power steering fluid reservoir. If low, top off with the manufacturer-recommended fluid.
Inspect the power steering pump for leaks.
- If leaks are found, replace the pump.
Examine the power steering belt for wear or damage.
- Replace if frayed or cracked.
If the pump and fluid are fine, inspect the steering rack for any signs of wear or damage.
- Replace the steering rack if necessary.

4. Steering System Adjustment

If the steering wheel is off-center, check the alignment.
Adjust the alignment according to manufacturer specifications using an alignment machine.
If tire wear is uneven, replace tires as necessary.
