Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Change Engine Oil and Filter

Tools Required: Socket set, oil filter wrench, oil catch pan.
Sub-steps:
1. Place the oil catch pan beneath the oil pan.
2. Remove the oil drain plug and allow the old oil to completely drain.
3. Remove the old oil filter using the oil filter wrench.
4. Install a new oil filter, lubricating the rubber gasket with new oil.
5. Reinstall the oil drain plug and torque to manufacturer specifications (typically around 30 ft-lbs).
6. Refill the engine with the correct type and amount of oil (5W-20 is typical for the Honda Accord).

3. Inspect and Replace Oil Pressure Sending Unit

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Locate the oil pressure sending unit; it is typically near the oil filter.
2. Disconnect the electrical connector from the sending unit.
3. Remove the old sending unit using a socket.
4. Install the new sending unit and torque it to manufacturer specifications (usually around 12-15 ft-lbs).
5. Reconnect the electrical connector.

4. Test Oil Pressure

Tools Required: Mechanical oil pressure gauge.
Sub-steps:
1. Remove the oil pressure sending unit and install the mechanical gauge.
2. Start the engine and observe the oil pressure reading; it should be within the normal range (typically 25-65 psi at idle).
3. If pressure is low, further inspection of the oil pump and engine internals may be necessary.
