Solution

1. Preparation

Tools Required: Oil pressure gauge, wrench set, OBD-II scanner, oil filter wrench, socket set, replacement oil (as specified in owner's manual), replacement oil filter.
Safety Warnings: Ensure the engine is cool before starting work. Disconnect the battery before working on electrical components.

2. Check and Add Oil

Sub-steps:
1. Park the vehicle on a level surface and turn off the engine.
2. Remove the dipstick, wipe it clean, and reinsert it to check the oil level.
3. If oil level is low, add the appropriate type of oil as per the manufacturer’s specifications.

3. Replace Oil Filter (if necessary)

Sub-steps:
1. Remove the old oil filter using an oil filter wrench.
2. Apply a thin layer of new oil to the rubber gasket of the new oil filter.
3. Install the new oil filter by hand; tighten according to specifications (usually hand-tight plus a quarter turn).

4. Replace Oil Pressure Sending Unit (if faulty)

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector from the sending unit.
3. Use a wrench to remove the oil pressure sending unit and install a new one.
4. Reconnect the electrical connector.

5. Test Oil Pressure

Sub-steps:
1. Locate the oil pressure test port on the engine.
2. Remove the port’s cap and install the oil pressure gauge.
3. Start the engine and monitor the gauge for oil pressure readings; it should be within the manufacturer’s specified range.
4. If pressure is low, further inspection of the oil pump may be necessary.
