Solution

1. Preparation

Gather tools: oil pressure gauge, socket set, torque wrench, oil filter wrench, and a clean drain pan.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Oil

Check Oil Level
- Remove the dipstick and wipe it clean. Reinsert and remove again to check the oil level.
- If low, top off with the correct grade of engine oil as specified in the owner's manual.
Change Oil and Filter
- Place a drain pan under the oil pan.
- Remove the oil drain plug using a socket set and allow oil to fully drain.
- Replace the oil filter using an oil filter wrench, ensuring the rubber O-ring comes off with the old filter.
- Install the new oil filter and hand-tighten.
- Reinstall the drain plug and tighten to the manufacturer's specified torque.
Refill Engine Oil
- Pour the appropriate amount of fresh oil into the engine through the oil fill cap.
- Start the engine and let it run for a few minutes, checking for leaks around the oil filter and drain plug.

3. Replace Oil Pressure Sending Unit (if needed)

Locate Sending Unit
- Identify the oil pressure sending unit on the engine, usually near the oil filter.
Remove and Replace
- Disconnect the electrical connector from the sending unit.
- Remove the sending unit using a socket or wrench.
- Install the new sending unit and reconnect the electrical connector.
