Solution

1. Preparation

Gather all 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 and Filter

Sub-steps:
1. Place a drain pan under the oil pan and remove the oil drain plug using a socket set. Allow old oil to fully drain.
2. Replace the oil drain plug and tighten it to the manufacturer’s specifications (typically around 30 Nm).
3. Remove the old oil filter using an oil filter wrench. Lubricate the rubber O-ring on the new filter with fresh oil and install the new filter.

Tools Required:

Socket set
Oil filter wrench
Oil drain pan
New oil filter
Fresh engine oil (consult the owner's manual for the correct type and capacity)

3. Inspect and Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit, typically near the oil filter or on the engine block.
2. Disconnect the electrical connector from the sending unit.
3. Remove the sending unit using a socket or wrench.
4. Install the new oil pressure sending unit and tighten it to the manufacturer’s specifications.
5. Reconnect the electrical connector.

Tools Required:

Socket or wrench set

4. Test Oil Pressure

Sub-steps:
1. Install a mechanical oil pressure gauge in place of the oil pressure sending unit.
2. Start the engine and monitor the oil pressure gauge. Refer to the manufacturer’s specifications for normal oil pressure readings.
3. If oil pressure is low, further diagnosis may be required, such as checking for oil pump failure.
