Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Engine Oil Level

Remove the dipstick, clean it with a lint-free cloth, and reinsert it fully.
Pull the dipstick out again and check the oil level. If low, add the appropriate oil type until it reaches the "full" mark.

3. Inspect for Leaks

Visually inspect the engine and oil pan for any signs of oil leaks.
If leaks are found, clean the area and identify the source of the leak for further action.

4. Replace Oil Filter (if necessary)

Locate the oil filter; use an oil filter wrench to remove it.
Apply a thin layer of new oil to the gasket of the new filter before installation.
Install the new oil filter, ensuring it’s snug but not overtightened.

5. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, typically near the oil filter.
Disconnect the electrical connector and remove the sending unit using a socket wrench.
Install the new sending unit and reconnect the electrical connector.

6. Verify Oil Pump Functionality

If issues persist, the oil pump may need to be inspected or replaced. This typically requires removing the oil pan.
Remove the oil pan bolts and the pan itself to access the oil pump.
Inspect the pump for wear and replace it if necessary, following the manufacturer's specifications.
