Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Change Engine Oil

Drain Old Oil:
- Locate the oil drain plug and place an oil catch pan underneath.
- Remove the drain plug using a socket set and allow the old oil to drain completely.
- Reinstall the drain plug and tighten to manufacturer specification (typically around 20 lb-ft).
Replace Oil Filter:
- Locate the oil filter.
- Use an oil filter wrench to remove the old oil filter.
- Apply a thin layer of new oil to the rubber gasket of the new oil filter.
- Install the new oil filter by hand until snug, then tighten it according to specifications (usually about 3/4 turn after the gasket contacts the engine).
Add New Oil:
- Pour in the recommended type and amount of new engine oil (check owner's manual for specifications).
- Start the engine and let it idle for a few minutes, checking for leaks around the filter and drain plug.

3. Replace Oil Pressure Sending Unit (if faulty)

Locate and Remove:
- Identify the oil pressure sending unit, typically found near the oil filter.
- Disconnect the electrical connector.
- Use a socket to remove the sending unit.
Install New Sending Unit:
- Apply thread sealant to the new sending unit threads.
- Install the new sending unit and tighten to manufacturer specifications.
- Reconnect the electrical connector.
