Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the engine to cool if it has been running.

2. Check and Refill Oil

Sub-steps:
1. Remove the dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the oil level.
3. If low, add the appropriate type of oil (refer to the owner's manual) through the oil filler cap.
Tools Required: Oil funnel, appropriate engine oil.
Safety Warnings: Avoid touching hot engine components; ensure the engine is cool before proceeding.

3. Inspect and Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit (usually 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 by threading it into place and tightening it to the manufacturer's specifications (typically around 15-20 Nm).
5. Reconnect the electrical connector.
Tools Required: Socket set, torque wrench.
Safety Warnings: Ensure the engine is cool and avoid contact with hot surfaces.

4. Replace Oil and Filter

Sub-steps:
1. Place a drain pan under the oil pan and remove the oil drain plug; allow the old oil to drain completely.
2. Remove the old oil filter using an oil filter wrench.
3. Apply a small amount of new oil to the rubber gasket of the new oil filter.
4. Install the new oil filter and tighten it according to specifications (typically hand-tight).
5. Replace the oil drain plug and tighten it to the manufacturer's specifications (typically around 25-30 Nm).
6. Refill the engine with the correct amount of new oil through the oil filler cap.
Tools Required: Oil filter wrench, socket set, oil drain pan, funnel.
Safety Warnings: Be cautious of hot oil; allow it to cool before draining.
