Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery to prevent any electrical shorts.
2. Oil Change
  1. Drain Old Oil
    • Place an oil drain pan under the oil pan.
    • Remove the oil drain plug using a socket set (typically 17mm).
    • Allow the old oil to completely drain.
  2. Replace Oil Filter
    • Locate the oil filter and use an oil filter wrench to remove it.
    • Lubricate the rubber O-ring of the new oil filter with fresh oil.
    • Install the new oil filter by hand until snug, then tighten 3/4 turn more.
  3. Add New Oil
    • Reinstall the oil drain plug and tighten to manufacturer’s torque specification (usually around 30 ft-lbs).
    • Use a funnel to add the correct type and amount of new oil (typically 0W-20 for Honda Civic) through the oil filler cap.
    • Start the engine and let it idle for a minute, then check for leaks around the filter and drain plug.
3. Inspect and Replace Oil Pressure Sending Unit (if necessary)
  1. Locate the Oil Pressure Sending Unit
    • Find the oil pressure sending unit, usually located near the oil filter.
  2. Remove the Sending Unit
    • Disconnect the electrical connector.
    • Use a wrench to remove the sending unit.
  3. Install New Sending Unit
    • Apply thread sealant to the threads of the new unit.
    • Install the new sending unit and reconnect the electrical connector.
