Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather tools: dipstick, OBD-II scanner, socket set, oil filter wrench, oil catch pan.

2. Check and Add Oil

Sub-steps:
1. Remove the dipstick and wipe it clean.
2. Reinsert the dipstick fully, then remove it again to check the oil level.
3. If the oil level is low, add the correct type of engine oil (check owner's manual for specifications).
4. Recheck the level after adding oil; ensure it is between the minimum and maximum marks.

3. Change Engine Oil and Filter (if necessary)

Sub-steps:
1. Place an oil catch pan under the oil pan and remove the drain plug using a socket set.
2. Allow the old oil to drain completely.
3. Remove the old oil filter using an oil filter wrench.
4. Install the new oil filter, applying a thin layer of new oil to the rubber gasket before installation.
5. Reinstall the drain plug and tighten to the specified torque (typically around 25 Nm).
6. Fill the engine with new oil as specified in the owner's manual.

4. Check Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit (usually near the oil filter).
2. Disconnect the electrical connector and inspect for corrosion or damage.
3. Test the unit with a multimeter to ensure it functions correctly (refer to service manual for specifications).
4. Replace the sending unit if it is faulty.
