Solution

1. Preparation

Tools Required: OBD-II scanner, mechanical oil pressure gauge, socket set, torque wrench, oil filter wrench, and multimeter.
Safety Warnings: Disconnect the battery before working on electrical systems; allow engine to cool before opening any components.

2. Correct Oil Level

Sub-step 1: If the oil level is low, add the appropriate oil type as specified in the owner's manual.
Sub-step 2: Run the engine for a few minutes, then check the oil level again and adjust if necessary.

3. Replace Oil Filter

Sub-step 1: Use an oil filter wrench to remove the old oil filter.
Sub-step 2: Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Sub-step 3: Install the new oil filter, tightening it as per manufacturer specifications (usually hand-tight plus a quarter turn).

4. Check Oil Pump

Sub-step 1: Remove the oil pump (usually located at the bottom of the engine).
Sub-step 2: Inspect the oil pump for wear or damage. Replace if necessary.
Sub-step 3: Reinstall the oil pump and torque to manufacturer specifications.

5. Replace Oil Pressure Sending Unit

Sub-step 1: Locate the oil pressure sending unit, typically near the oil filter or engine block.
Sub-step 2: Disconnect the electrical connector and unscrew the sending unit.
Sub-step 3: Install the new sending unit and reconnect the electrical connector.
