why is my Toyota Corolla E140 (2006-2013) power steering not working

Solution

1. Preparation

• Gather tools and materials needed for the repair.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the battery to prevent electrical hazards.

2. Check and Refill Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level; add the appropriate type of power steering fluid if low (refer to the owner's manual for specifications).
• Inspect the fluid for contamination (dark color or debris) and replace if necessary.

3. Inspect and Replace Damaged Components

• Hoses:
  • Inspect all power steering hoses for signs of wear, cracking, or leaks.
  • Replace any damaged hoses using a socket set and appropriate hose clamps.
• Power Steering Pump:
  • If the pump is noisy or does not circulate fluid, it may need replacement.
  • Remove the pump by disconnecting the hoses and unbolting it from the engine.
  • Install the new pump and reconnect all hoses, ensuring no leaks.

4. Check and Replace Steering Rack (if necessary)

• If the steering rack is damaged or leaking, it will need to be replaced.
• Lift the vehicle and secure it on jack stands.
• Disconnect the tie rods from the steering rack.
• Remove any brackets or bolts securing the rack.
• Install the new steering rack, reconnect tie rods, and ensure proper alignment.

5. Refill and Bleed the System

• After replacing components, refill the power steering fluid reservoir.
• Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
• Check fluid level again and add as necessary.
