Solution

1. Preparation

Gather tools: oil pressure gauge, socket set, wrench set, oil filter wrench, and a new oil filter.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Check and Add Engine Oil

Sub-steps:
1. Remove the dipstick and wipe it clean.
2. Insert the dipstick back into the tube and remove it again to check the oil level.
3. If low, add the appropriate type and amount of oil (5W-30 or as specified in the owner's manual).

3. Replace the Oil Filter (if necessary)

Sub-steps:
1. Locate the oil filter and use the oil filter wrench to remove it.
2. Lubricate the rubber gasket of the new oil filter with new oil.
3. Install the new oil filter by hand, tightening it securely without over-tightening.

4. Inspect and Replace Oil Pressure Sending Unit (if faulty)

Sub-steps:
1. Disconnect the battery before starting work on the electrical components.
2. Locate the oil pressure sending unit, typically near the oil filter.
3. Disconnect the electrical connector and unscrew the sending unit using a wrench.
4. Install the new sending unit and reconnect the electrical connector.

5. Test Oil Pressure

Sub-steps:
1. Install the oil pressure gauge in place of the oil pressure sending unit.
2. Start the engine and observe the oil pressure reading.
3. If the pressure is within normal range (usually 20-60 psi at idle), reinstall the sending unit.
