Solution

1. Preparation

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

2. Check and Replace Engine Oil

Sub-step 1: Remove the oil drain plug using a socket set and allow the old oil to drain into a pan.
Sub-step 2: Replace the oil filter using an oil filter wrench. Ensure the rubber O-ring from the old filter is not stuck to the engine.
Sub-step 3: Install the new oil filter and tighten it according to the manufacturer's specifications (usually hand-tight plus ¾ turn).
Sub-step 4: Reinstall the oil drain plug and torque it to the manufacturer's specifications (typically around 20 Nm).
Sub-step 5: Fill the engine with the correct type and amount of engine oil (5W-30 or as specified in the owner’s manual).

3. Replace Oil Pressure Sending Unit (if necessary)

Sub-step 1: Locate the oil pressure sending unit, typically found near the oil filter or on the engine block.
Sub-step 2: Disconnect the electrical connector and remove the sending unit using a socket or wrench.
Sub-step 3: Install the new oil pressure sending unit and connect the electrical connector.
Sub-step 4: Ensure all connections are secure and free of leaks.

4. Inspect and Replace Oil Pump (if necessary)

Sub-step 1: Remove the engine oil pan by loosening the bolts and carefully prying it off.
Sub-step 2: Remove the oil pump from its mounting location, taking care to note the orientation and any gaskets.
Sub-step 3: Install the new oil pump, ensuring proper alignment and sealing.
Sub-step 4: Reinstall the oil pan and torque the bolts to the specified values.
