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 prevent electric shock while working on the vehicle.

2. Check Oil Level and Condition

Remove the dipstick and wipe it clean.
Insert the dipstick back and then remove it again to check the oil level.
If oil is low, add the recommended oil type (5W-20 for the Honda Accord).
If the oil appears dirty or contaminated, proceed to the next step.

3. Change Engine Oil and Filter

Tools Required: Oil filter wrench, socket set, oil catch pan, funnel.
Place the oil catch pan under the oil pan.
Remove the oil drain plug using a socket and allow the oil to fully drain.
Replace the oil drain plug and torque it to the manufacturer’s specifications (typically around 30 lb-ft).
Remove the old oil filter with the oil filter wrench.
Install a new oil filter, lubricating the rubber O-ring with fresh oil before installation.
Fill the engine with the recommended type and amount of new oil using a funnel.

4. Check Oil Pressure

Install an oil pressure gauge in place of the oil pressure sending unit.
Start the engine and observe the pressure readings.
If the pressure is low, replace the oil pressure sending unit.

5. Inspect and Replace Oil Pressure Sending Unit (if necessary)

Tools Required: Socket set, torque wrench.
Disconnect the battery.
Locate the oil pressure sending unit, usually near the oil filter.
Remove the electrical connector from the sending unit.
Unscrew the sending unit using a socket.
Install the new oil pressure sending unit and torque it to specifications (often around 15 lb-ft).
Reconnect the electrical connector.

6. Recheck Oil Level

After repairs, check the oil level again with the dipstick and add oil if necessary.
