what should I check if my Toyota Corolla E170 (2013-2019) has a warning light for power steering?

Solution

1. Preparation

• Gather necessary tools and ensure the vehicle is parked on a level surface.
• Disconnect the negative battery terminal to ensure safety while working on the electrical components.

2. Check Fluid Level

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level against the markings.
  • If low, add the recommended power steering fluid (usually Dexron II or III).
  • Replace the cap securely.

3. Inspect Power Steering Pump

• Locate the power steering pump mounted on the engine.
• Visually inspect for any signs of leakage or damage.
• If leaking, proceed to replace the pump.
  • Tools Required: Socket set, wrench set.
  • Sub-steps:
    1. Remove the drive belt by loosening the tensioner.
    2. Disconnect the hoses from the pump; be prepared for fluid spillage.
    3. Remove the mounting bolts and take out the pump.
    4. Install the new pump by reversing the removal steps.
    5. Refill the fluid and bleed the system as necessary.

4. Inspect Steering Rack and Linkage

• Check the steering rack for any leaks or damage.
• Ensure that the linkage is secure and free of play.
  • If repairs are needed, replace worn components accordingly.

5. Test Electrical Components

• Inspect the fuses related to the power steering system (refer to the fuse box diagram).
• Replace any blown fuses.
• Check electrical connectors for any corrosion or loose connections.
