Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Check and Replace Engine Oil

Sub-steps:
1. Remove the oil filler cap and locate the oil drain plug underneath the vehicle.
2. Place a drain pan under the oil drain plug and remove the plug using a socket wrench.
3. Allow the old oil to drain completely into the pan.
4. Replace the drain plug and torque it to the manufacturer's specification (usually around 30 ft-lbs).
5. Refill the engine with new oil that meets Honda specifications (typically 5W-20).
6. Start the engine and let it idle for a minute, then check the oil level again using the dipstick.

3. Replace Oil Filter

Tools Required: Oil filter wrench
Sub-steps:
1. Use the oil filter wrench to remove the old oil filter.
2. Apply a thin layer of new oil to the rubber gasket of the new oil filter.
3. Install the new oil filter by hand until snug, then turn it an additional 3/4 turn.
4. Ensure there are no leaks after installation.

4. Inspect and Replace Oil Pressure Sending Unit (if applicable)

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector and use a wrench to remove the sending unit.
3. Install the new sending unit and reconnect the electrical connector.
4. Start the engine and check for oil pressure warning light.
