Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Change Engine Oil and Filter

Sub-steps:
1. Remove the oil drain plug and drain the old oil into a suitable container.
2. Replace the oil filter using an oil filter wrench; lubricate the rubber O-ring on the new filter with fresh oil.
3. Replace the drain plug and tighten to manufacturer specifications (typically around 20 lb-ft).
4. Refill the engine with the correct type and amount of oil (5W-20 or as specified in the owner's manual).

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit on the engine block.
2. Disconnect the electrical connector from the sending unit.
3. Use a socket to unscrew and remove the old sending unit.
4. Install the new sending unit and tighten to the manufacturer's torque specifications (typically around 15 lb-ft).
5. Reconnect the electrical connector.

4. Inspect and Test Oil Pump (if necessary)

Sub-steps:
1. Remove any components obstructing access to the oil pump.
2. Inspect the oil pump visually for signs of wear or damage.
3. If testing is required, consult the service manual for specific testing procedures.
4. Replace the oil pump if it is found defective.
