Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using jack stands and secure it.
2. Remove the oil drain plug and drain old oil into a catch pan.
3. Replace the oil filter using an oil filter wrench. Lubricate the rubber O-ring on the new filter with a bit of fresh oil before installing.
4. Reinstall the oil drain plug with a torque wrench, tightening to the manufacturer’s specified torque (typically around 20 ft-lbs).

3. Inspect and Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit (usually found near the oil filter).
2. Disconnect the electrical connector from the sending unit.
3. Use a socket wrench to remove the sending unit.
4. Install the new sending unit and torque it according to manufacturer specifications.
5. Reconnect the electrical connector.

4. Test Oil Pressure

Sub-steps:
1. Connect a mechanical oil pressure gauge to the oil pressure sending unit port.
2. Start the engine and observe the oil pressure reading. It should be within the manufacturer's specified range (typically between 25-65 psi at idle).
3. If the pressure is low, further investigations into the oil pump or engine wear may be required.
