Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and a fluid pump.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Disconnect the battery to prevent any electrical shorts.
2. Address Fluid Issues
  • Check Fluid Level:
    • Locate the power steering reservoir.
    • Remove the cap and check the fluid level against the dipstick or markings.
  • Top Off Fluid:
    • If low, add the recommended power steering fluid (refer to the owner's manual for specifications).
    • Reattach the reservoir cap securely.
3. Inspect Electrical Connections
  • Visual Inspection:
    • Examine the wiring harness and connectors leading to the power steering pump and steering angle sensor.
  • Reconnect Loose Wires:
    • If any connections are loose or corroded, clean and reconnect them securely.
4. Replace Faulty Components
  • Steering Angle Sensor:
    • If the sensor is faulty, disconnect it and remove it from its mount.
    • Install the new sensor, ensuring it is aligned correctly.
    • Reconnect the electrical connector.
  • Power Steering Pump:
    • If diagnosed as faulty, disconnect the hydraulic lines and electrical connections.
    • Remove the pump from its mounting bracket.
    • Install the new pump, reconnecting all lines and ensuring they are torqued to specifications.
5. Reassemble and Test
  • Reconnect the battery and start the vehicle.
  • Turn the steering wheel from lock to lock to bleed any air from the system.
  • Check for leaks around the power steering components.
