Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Top Up Engine Oil

Sub-steps:
- Remove the dipstick, wipe it clean, and insert it back into the tube.
- Pull out the dipstick again and check the oil level.
- If low, add the recommended oil type (5W-20 for Honda Pilot).
- Start the engine and allow it to run for a few minutes, then recheck the oil level.

3. Inspect and Replace Oil Pressure Sending Unit

Sub-steps:
- Locate the oil pressure sending unit on the engine block.
- Disconnect the electrical connector by pressing the tab and pulling.
- Use a wrench to unscrew the old sending unit and remove it.
- Install the new sending unit, ensuring a proper seal.
- Reconnect the electrical connector.

4. Test Oil Pressure

Sub-steps:
- Remove the oil pressure sending unit using a socket set.
- Install a mechanical oil pressure gauge in its place.
- Start the engine and observe the gauge reading; it should be within the manufacturer’s specifications (typically 20-60 psi at idle).
- If pressure is low, further investigation is needed for oil pump failure or internal engine issues.

5. Inspect and Replace Oil Filter

Sub-steps:
- Locate the oil filter; use an oil filter wrench to remove it.
- Check the filter for signs of blockage or damage.
- Apply a thin layer of new oil to the rubber gasket of the new filter.
- Install the new filter, tightening it according to the manufacturer’s specifications (usually hand-tight plus a quarter turn).
