Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Remove the oil dipstick and wipe it clean.
Reinsert the dipstick fully, then remove it again to check the oil level.
If low, add the appropriate engine oil (check manufacturer specifications) through the oil filler cap.
Recheck the oil level after adding oil.

3. Replace Oil Filter (if necessary)

Tools Required: Oil filter wrench, socket set
Place an oil catch pan under the oil filter to catch any spills.
Use the oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter by hand until snug, then tighten slightly with the wrench.

4. Check and Replace Oil Pressure Sending Unit (if faulty)

Tools Required: Socket set, wrench set
Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector from the sending unit.
Remove the sending unit using the appropriate socket.
Install the new sending unit and reconnect the electrical connector.

5. Test Oil Pressure

Tools Required: Mechanical oil pressure gauge
Remove the oil pressure sending unit and install the mechanical gauge.
Start the engine and observe the pressure reading; it should be within the manufacturer’s specified range.
If the pressure is low, further inspection of the oil pump and engine internals may be required.
