Solution

1. Preparation

Tools Required:
- Socket set
- Oil filter wrench
- Multimeter
- Mechanical oil pressure gauge
- Rags for cleanup
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check Oil Level and Condition

Remove the dipstick, wipe it clean, reinsert it, and remove it again to check the oil level.
If the oil is low, add the correct type and viscosity of oil as specified in the owner's manual.
If the oil is dirty or contaminated, proceed to change the oil and filter.

3. Change Oil and Filter

Sub-steps:
1. Raise the vehicle using jack stands for safety.
2. Place a drain pan under the oil pan.
3. Remove the oil drain plug and allow the old oil to completely drain.
4. Replace the oil drain plug and tighten it to the manufacturer's torque specification (usually around 30 lb-ft).
5. Remove the old oil filter using an oil filter wrench.
6. Lubricate the rubber gasket of the new oil filter with fresh oil and install it, tightening securely.
7. Fill the engine with the correct amount of new oil through the oil filler cap.

4. Inspect and Replace Sending Unit (if necessary)

Sub-steps:
1. Locate the oil pressure sending unit, usually near the oil filter.
2. Disconnect the electrical connector from the sending unit.
3. Using a wrench, remove the sending unit.
4. Install the new sending unit and connect the electrical connector.
5. Test the oil pressure using a mechanical gauge to confirm proper operation.

5. Verify Oil Pump Operation (if necessary)

If oil pressure is still low after the above steps:
1. Remove the oil pan.
2. Inspect the oil pump for wear or damage.
3. Replace the oil pump if it is malfunctioning, ensuring proper installation according to the manufacturer's specifications.
