Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check and Add Engine Oil

Tools Required: Oil filter wrench, funnel, clean rags, and a container for used oil.
Remove the oil filler cap and check the oil level using the dipstick.
If the oil level is low, add the appropriate type and amount of oil (refer to owner's manual).
Recheck the oil level after adding oil and replace the cap securely.

3. Inspect the Oil Pressure Sending Unit

Tools Required: Wrench set, O-ring or thread sealant (if replacing).
Locate the oil pressure sending unit; it is usually near the oil filter.
Disconnect the electrical connector and remove the unit using the appropriate wrench.
Inspect the unit for any signs of damage or leakage. Replace if necessary.
Reinstall the new sending unit and reconnect the electrical connector.

4. Replace Oil Filter (if necessary)

Tools Required: Oil filter wrench, clean rags, oil catch pan.
Place an oil catch pan under the oil filter.
Use an oil filter wrench to remove the old oil filter; ensure the rubber O-ring comes off with it.
Apply a small amount of new oil to the O-ring of the new filter.
Install the new oil filter by hand until snug, then tighten it slightly more with the wrench.

5. Check Oil Pump Functionality

Tools Required: Oil pressure gauge, wrench set.
Remove the oil pressure sending unit and install an oil pressure gauge in its place.
Start the engine and monitor the oil pressure reading; it should be within specification (refer to owner's manual).
If the pressure is low, the oil pump may need replacement or further inspection.
