Repair Instructions

1. Refill Power Steering Fluid:

If the fluid level is low, top it up with the appropriate power steering fluid.
Start the engine, turn the steering wheel from side to side to bleed any air, and check the fluid level again.

2. Check and Replace Power Steering Pump (if defective):

If the pump is making noise or is found to be leaking:
- Disconnect the negative battery terminal.
- Remove the serpentine belt from the power steering pump.
- Disconnect the power steering lines (be prepared for fluid spills).
- Remove the mounting bolts and take out the power steering pump.
- Install the new pump by reversing the removal steps. Make sure to replace any O-rings or seals.

3. Inspect and Replace Drive Belt (if necessary):

If the drive belt is damaged or worn, replace it:
- Use a serpentine belt tool to relieve tension and remove the old belt.
- Install the new belt according to the belt routing diagram (usually located on a sticker under the hood).

4. Repair Electrical Issues:

If the EPS system is not functioning correctly:
- Inspect the wiring harness and connectors for corrosion or damage.
- If any issues are found, repair or replace the damaged components.
- If no visible issues are found, consider replacing the EPS motor or steering angle sensor, which may require dealer-level diagnostics.

5. Clear Codes and Test Drive:

Clear any diagnostic trouble codes using the OBD-II scanner.
Reconnect the battery and take the vehicle for a test drive to confirm that the power steering is functioning correctly.

Conclusion

After completing the above steps, the power steering system in your 2021 Toyota Camry should be restored. If the problem persists, it may be best to consult a professional technician or visit a Toyota dealership for in-depth diagnostics.
