Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Check and Replace Engine Oil

Remove the oil filler cap and check the oil level using the dipstick.
If the oil level is low, add the correct type of oil as specified in the owner's manual.
If the oil is dirty or old, drain the old oil using a socket set and oil drain pan.
Replace with fresh oil of the appropriate viscosity and specification.

3. Inspect and Replace Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Apply a small amount of new oil to the rubber O-ring of the new oil filter.
Install the new oil filter and tighten it according to the manufacturer's specifications (typically hand-tight plus 3/4 turn).
Refill the engine with oil if drained during the filter replacement.

4. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, usually near the oil filter or engine block.
Disconnect the electrical connector and remove the unit using a socket set.
Install the new oil pressure sending unit and reconnect the electrical connector.

5. Verify Oil Pump Functionality

If issues persist, the oil pump may need to be inspected or replaced.
Follow manufacturer guidelines for removal and installation, ensuring all connections are sealed properly.
