Solution

1. Preparation

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

2. Check and Add Engine Oil

Sub-steps:
- Remove the oil fill cap located on top of the engine.

3. Replace Oil Pressure Sending Unit

Tools Required: Socket set, torque wrench, oil catch pan
Sub-steps:
- Locate the oil pressure sending unit (usually near the oil filter).
- Disconnect the electrical connector and unscrew the sending unit using a socket.
- Install the new sending unit by screwing it in place; torque to manufacturer specifications (typically around 15-20 ft-lbs).
- Reconnect the electrical connector.

4. Replace Engine Oil and Filter

Tools Required: Oil filter wrench, oil catch pan, socket set
Sub-steps:
- Place an oil catch pan underneath the oil pan.
- Remove the drain plug and allow the old oil to drain completely.
- Replace the drain plug and torque to specifications.
- Remove the old oil filter using an oil filter wrench.
- Install the new oil filter, lubricating the gasket with new oil and tightening by hand.
- Fill the engine with the recommended oil type through the oil fill cap.

5. Final Checks

Sub-steps:
- Reconnect the battery.
- Start the engine and let it idle for a few minutes.
- Check for leaks around the oil filter and sending unit.
- Turn off the engine and recheck the oil level, adding more if necessary.
