Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery to ensure safety.
2. Change Engine Oil and Filter

  1. Drain Old Oil

    • Place an oil catch pan under the oil pan.
    • Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
    • Reinstall the drain plug and torque it to the manufacturer’s specifications (typically around 20 ft-lbs).

  2. Replace Oil Filter

    • Locate the oil filter and use an oil filter wrench to remove it.
    • Apply a thin layer of new oil to the rubber gasket of the new oil filter.
    • Install the new oil filter by hand and tighten it according to the manufacturer’s specifications.

  3. Add New Oil

    • Use the recommended oil type (usually 0W-20 for Honda CR-V).
    • Pour the new oil into the engine through the oil filler cap, using a funnel to avoid spills.
    • Check the oil level with the dipstick and add oil as necessary to reach the correct level.
3. Inspect Oil Pressure Sending Unit

  1. Locate and Test

    • Locate the oil pressure sending unit, typically near the oil filter or on the engine block.
    • Disconnect the electrical connector and use a multimeter to test the unit’s resistance as per specifications.

  2. Replace if Necessary

    • If the unit is faulty, use a socket wrench to remove it and install the new sending unit.
    • Reconnect the electrical connector.
