Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (negative terminal) to prevent any electrical shorts.

2. Inspect and Replace Oil Filter

Sub-steps:
1. Place an oil catch pan under the oil filter.
2. Remove the old oil filter using an oil filter wrench.
3. Apply a thin layer of new oil to the rubber gasket on the new filter.
4. Install the new oil filter, hand-tightening it securely.
Tools Required: Oil filter wrench, oil catch pan.

3. Change Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench and allow the oil to drain completely into the catch pan.
2. Replace the oil drain plug with a new washer and torque to the manufacturer’s specification (typically around 25 Nm).
3. Refill the engine with the appropriate grade and type of oil (consult the owner’s manual; typically 5W-30 or 0W-40).
Tools Required: Socket set, funnel.

4. 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 reconnect the electrical connector.
Tools Required: Socket set, wrench set.

5. Reconnect Battery

Reattach the negative battery terminal and ensure it is securely tightened.
