Solution

1. Preparation

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

2. Change Engine Oil

Sub-steps:
1. Place a drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench and allow the oil to fully drain.
3. Replace the oil drain plug and torque it to the manufacturer’s specification (typically around 25 Nm).
4. Remove the old oil filter using an oil filter wrench.
5. Prepare the new oil filter by applying a thin layer of new oil to the rubber gasket.
6. Install the new oil filter and tighten it by hand until snug.
7. Refill the engine with the correct type and amount of oil (consult the owner's manual, usually around 5-6 liters of 5W-30 or similar).

3. Replace Oil Pressure Sensor (if necessary)

Sub-steps:
1. Locate the oil pressure sensor (usually near the oil filter).
2. Disconnect the electrical connector from the sensor.
3. Remove the sensor using a socket or wrench.
4. Install the new oil pressure sensor and tighten it to the manufacturer's specification (usually around 20 Nm).
5. Reconnect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan by unbolting it and cleaning the mating surfaces.
2. Remove the oil pump from the engine block.
3. Inspect the pump for wear; replace if damaged.
4. Install the new oil pump, ensuring proper alignment and sealing.
5. Reattach the oil pan with a new gasket and torque the bolts to the specified values (typically around 10 Nm).
