Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is on a level surface.
Disconnect the battery for safety.

2. Check and Top Up Engine Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate type of oil (5W-20 recommended) until the level is within the markings on the dipstick.

3. Replace Oil Filter

Place an oil catch pan under the oil filter.
Use an oil filter wrench to remove the old oil filter.
Clean the mounting surface on the engine.
Apply a thin layer of new oil to the rubber gasket of the new filter.
Install the new oil filter and tighten it according to the manufacturer's specifications (usually hand-tight).

4. Replace or Repair Oil Pressure Sending Unit

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

5. Inspect and Replace Oil Pump (if necessary)

If low oil pressure persists, it may be due to a failing oil pump.
Drain the engine oil completely.
Remove the oil pan by unbolting it and carefully prying it loose.
Remove the old oil pump by unbolting it from the engine block.
Install the new oil pump, ensuring proper alignment and tightening bolts to the specified torque (consult service manual for exact torque values).
Reinstall the oil pan with a new gasket and tighten the bolts.
