Solution

1. Preparation

Gather all tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Safety: Allow the engine to cool before working on it.

2. Check and Refill Engine Oil

Sub-steps:
1. Remove the dipstick and clean it with a lint-free cloth.
2. Reinsert the dipstick and remove it again to check the oil level.
3. If the oil level is low, add the correct type and amount of oil (typically 0W-20 for Toyota RAV4).
4. Start the engine and let it idle for a few minutes to circulate the oil.
5. Check the dipstick again to ensure proper oil level.

3. Replace Oil Filter

Sub-steps:
1. Turn off the engine and allow it to cool.
2. Locate the oil filter (usually on the bottom of the engine).
3. Use an oil filter wrench to remove the old oil filter.
4. Apply a small amount of new oil to the rubber gasket of the new filter.
5. Install the new oil filter and tighten it according to the manufacturer's specifications (typically hand-tight plus 3/4 turn).

4. Inspect and Replace the Oil Pump (if necessary)

Sub-steps:
1. Disconnect the battery to prevent any electrical issues.
2. Remove the engine oil pan by unbolting it and draining the oil.
3. Inspect the oil pump for wear or damage; replace if necessary.
4. Reinstall the oil pan with a new gasket, ensuring all bolts are torqued to specification.

5. Clear Error Codes and Test

Sub-steps:
1. Reconnect the battery.
2. Use an OBD-II scanner to clear any stored error codes.
3. Start the engine and monitor the oil pressure warning light.
