Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Change Engine Oil and Filter

Sub-steps:
1. Remove the oil drain plug using a socket set and drain the old oil into a pan.
2. Replace the oil filter with a new one, using an oil filter wrench to remove the old filter and lubricating the rubber gasket on the new filter.
3. Reinstall the oil drain plug and torque it to the manufacturer specifications (typically around 25 ft-lbs).
4. Fill the engine with the appropriate type and amount of oil (usually 5W-20 or 0W-20 for the RAV4).

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit, usually found near the oil filter.
2. Disconnect the electrical connector from the sending unit.
3. Use a wrench to unscrew the old sending unit and replace it with a new one.
4. Reconnect the electrical connector securely.

4. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. If low oil pressure persists after the previous steps, remove the oil pan by unscrewing the bolts holding it in place.
2. Inspect the oil pump for damage or wear; if faulty, remove it by unscrewing and replacing it with a new pump.
3. Reinstall the oil pan with a new gasket and torque the bolts to specifications (generally around 9-12 ft-lbs).
