Solution

1. Preparation

Gather tools such as an oil pressure gauge, socket set, and a basin for oil collection.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Top Off Engine Oil

Sub-steps:
1. Open the hood and locate the dipstick.
2. Remove and wipe the dipstick clean, then reinsert it fully.
3. Pull it out again and check the oil level; if below the minimum mark, add the appropriate oil type (0W-20 for Honda Accord).
4. Start the engine and let it run for a minute, then check the oil level again.

3. Inspect and Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector from the sending unit.
3. Remove the sending unit using a socket wrench.
4. Install the new sending unit and reconnect the electrical connector.

4. Test Oil Pressure

Sub-steps:
1. Remove the oil pressure sending unit and install the oil pressure gauge.
2. Start the engine and observe the pressure reading; it should be within the manufacturer’s specifications (typically 25-65 psi at idle).
3. If pressure is low, consider replacing the oil pump or checking for internal engine issues.

5. Change Engine Oil and Filter

Sub-steps:
1. Place a basin under the oil pan and remove the drain plug to allow old oil to drain out.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the drain plug and torque it to manufacturer specifications (typically 25-30 ft-lbs).
4. Add new engine oil through the oil filler cap.
