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 avoid electrical issues.

2. Change Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench and allow the old oil to drain completely into a container.
2. Replace the oil filter using an oil filter wrench. Lubricate the gasket of the new filter with a small amount of fresh oil before installation.
3. Reinstall the drain plug and torque it to the manufacturer’s specification (usually around 20-25 lb-ft).
4. Refill the engine with the appropriate type and amount of oil as specified in the owner’s manual (typically 5W-20 or 0W-20 for most Honda Accords).

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit, usually found near the oil filter or on the engine block.
2. Disconnect the electrical connector from the sending unit.
3. Use a socket to unscrew and remove the old sending unit.
4. Install the new sending unit and torque it to manufacturer specifications.
5. Reconnect the electrical connector.

4. Verify Oil Pressure

Sub-steps:
1. Reconnect the battery.
2. Start the engine and let it idle.
3. Use the oil pressure gauge to check if the oil pressure readings are within the normal range (typically 25-65 psi at idle).
