1. Preparation

Gather tools and parts needed for the repair.
Ensure the engine is cool and the vehicle is on a flat surface.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket set, and drain the old oil into a suitable container.
2. Replace the oil filter using an oil filter wrench; ensure the rubber O-ring comes off with the old filter.
3. Install a new oil filter, lubricating the O-ring with a bit of new oil before installation.
4. Reinstall the oil drain plug and torque it to 25 lb-ft.
5. Add the appropriate type and amount of engine oil (consult the owner's manual for specifications).

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit, typically found near the oil filter or the engine block.
2. Disconnect the electrical connector from the sending unit.
3. Use a wrench to unscrew the old sending unit from the engine.
4. Apply thread sealant to the new sending unit and install it, tightening to the manufacturer's specifications.
5. Reconnect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan by loosening the bolts with a socket set and carefully prying it off.
2. Inspect the oil pump for wear or damage; if faulty, remove it by loosening the mounting bolts.
3. Install a new oil pump, ensuring proper alignment and tightness of the bolts.
4. Reinstall the oil pan with a new gasket, torquing bolts to the manufacturer's specifications.
