Solution

1. Preparation

Gather the required tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid any electrical issues during the repair.

2. Check Oil Level

Remove the dipstick, wipe it clean, and reinsert it.
Pull the dipstick out again to check the oil level; add oil if low, using the recommended type (0W-20 for most models).
If the oil is dirty or contaminated, proceed to the next step.

3. Change Engine Oil and Filter

Tools Required: Socket set, oil filter wrench, oil catch pan, funnel.
Place the oil catch pan under the oil pan and remove the oil drain plug.
Allow the oil to drain completely, then replace the drain plug and tighten to the manufacturer's torque specification (typically around 30 ft-lbs).
Remove the old oil filter using the oil filter wrench. Apply a thin layer of new oil to the rubber gasket of the new filter, then install the new filter.
Refill the engine with fresh oil using the funnel.

4. Inspect and Replace Oil Pressure Sending Unit (if necessary)

Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector and remove the sending unit using a socket.
Install the new sending unit and reconnect the electrical connector.

5. Inspect Oil Pump (if necessary)

If low oil pressure persists, the oil pump may need inspection or replacement.
Remove the engine oil pan by unscrewing the bolts and lowering it carefully.
Inspect the oil pump for wear or damage, and replace it if necessary.
