Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and turn off the engine.
Allow the engine to cool down before proceeding.
Disconnect the negative battery terminal to ensure safety.

2. Check and Top Up Engine Oil

Locate the engine oil filler cap on the top of the engine.
Remove the cap and pour the appropriate type of oil (SAE 0W-20) into the engine.
Replace the cap securely and reconnect the battery.

3. Inspect and Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, typically found near the oil filter.
Disconnect the electrical connector from the sending unit.
Use a socket wrench to remove the sending unit from the engine.
Install the new oil pressure sending unit by reversing the removal steps and torque it to the manufacturer's specification (usually around 14-18 ft-lbs).
Reconnect the electrical connector.

4. Change Engine Oil and Oil Filter

Place an oil drain pan underneath the oil pan.
Remove the oil drain plug with a socket and let the old oil drain completely.
Replace the oil drain plug and torque it to specification (usually around 30 ft-lbs).
Remove the old oil filter using an oil filter wrench and install the new filter, ensuring the rubber gasket is lubricated and properly seated.
Fill the engine with new oil (SAE 0W-20) through the oil filler cap, using the correct amount (typically 4.5 quarts).

5. Verify Oil Pump Operation

If symptoms persist, check the oil pump for proper function.
This may require removing the oil pan to access the pump for inspection or replacement if faulty.
