Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Change Engine Oil and Filter

Tools Required: Socket set, oil filter wrench, oil catch pan, funnel.
Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Place the oil catch pan under the oil pan.
3. Remove the oil drain plug with the socket set and allow old oil to fully drain.
4. Replace the oil drain plug and torque to manufacturer's specifications (typically around 30 ft-lbs).
5. Use the oil filter wrench to remove the old oil filter.
6. Apply a small amount of new oil to the rubber gasket of the new oil filter.
7. Install the new oil filter, tightening it by hand until it's snug.

3. Inspect Oil Pressure Sending Unit

Tools Required: Socket set or wrench.
Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector.
3. Remove the sending unit using the appropriate socket.
4. Inspect for damage or leaks and replace if necessary.

4. Test Oil Pressure

Tools Required: Mechanical oil pressure gauge.
Sub-steps:
1. Remove the oil pressure sending unit and install the mechanical gauge.
2. Start the engine and observe the gauge reading.
3. If pressure is still low, further inspection of the oil pump may be necessary.

5. Inspect Oil Pump (if needed)

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Drain the oil again and remove the oil pan.
2. Inspect the oil pump for wear or damage.
3. Replace the oil pump if necessary, following manufacturer specifications for torque and installation.
