Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the engine is cool and parked on a level surface.
  • Disconnect the battery to avoid electrical issues.
2. Check and Replace Engine Oil

  1. Drain the Old Oil

    • Place a drain pan under the oil pan.
    • Remove the oil drain plug and allow the old oil to fully drain.
    • Reinstall the drain plug and torque to manufacturer specifications (typically around 25 Nm).

  2. Replace Oil Filter

    • Locate the oil filter and remove it using an oil filter wrench.
    • Apply a thin layer of new oil to the rubber gasket of the new filter.
    • Install the new oil filter and tighten it according to manufacturer specifications (generally hand-tight).

  3. Add New Oil

    • Pour the recommended type and amount of new engine oil into the engine (refer to owner's manual).
    • Start the engine and let it run for a few minutes, then check the oil level again and top off as necessary.
3. Replace Oil Pressure Sending Unit (if faulty)

  1. Locate the Oil Pressure Sending Unit

    • Find the oil pressure sending unit on the engine block.

  2. Disconnect Electrical Connector

    • Carefully unplug the electrical connector from the sending unit.

  3. Remove the Sending Unit

    • Use a socket wrench to unscrew the sending unit from the engine.

  4. Install New Sending Unit

    • Screw in the new sending unit and tighten it to the specified torque.
    • Reconnect the electrical connector.
