Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the negative battery cable to prevent electrical issues.

2. Check and Add Oil

Tools Required: Oil funnel, new engine oil as per manufacturer specification.
Steps:
1. Remove the oil filler cap.
2. Using an oil funnel, add the appropriate type and amount of oil.
3. Replace the oil filler cap securely.

3. Replace Oil Pressure Sending Unit

Tools Required: Socket set, wrench set, oil catch pan, new oil pressure sending unit.
Steps:
1. Place an oil catch pan under the oil pressure sending unit to catch any oil that may spill.
2. Locate the oil pressure sending unit (typically near the oil filter).
3. Disconnect the electrical connector from the sending unit.
4. Use the socket to remove the sending unit from the engine block.
5. Install the new oil pressure sending unit and tighten it to the manufacturer's torque specifications (usually around 15-20 ft-lbs).
6. Reconnect the electrical connector.

4. Change Engine Oil and Filter

Tools Required: Oil filter wrench, socket set, oil catch pan, new oil filter, new engine oil.
Steps:
1. Place an oil catch pan under the oil pan.
2. Remove the oil drain plug and allow the old oil to drain completely.
3. Replace the oil drain plug and tighten it to the manufacturer's specifications (typically around 20-25 ft-lbs).
4. Use an oil filter wrench to remove the old oil filter.
5. Lubricate the rubber gasket on the new oil filter with a bit of new oil, then install it by hand until snug.
6. Add new engine oil through the oil filler cap.

5. Reconnect Battery and Start Engine

Steps:
1. Reconnect the negative battery cable.
2. Start the engine and let it idle for a few minutes.
3. Check for leaks around the oil pressure sending unit and oil filter.
4. Monitor the oil pressure warning light; it should turn off if the issue is resolved.
