my Honda Civic 10th Generation (2016-2021) has low oil pressure warning, what does it mean?

Solution

1. Preparation

• Gather tools and materials.
• Ensure the vehicle is on a flat surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts.

2. Check and Top Off Oil

• Sub-steps:
  1. Locate the dipstick and remove it.
  2. Wipe it clean, reinsert, and remove again to check the oil level.
  3. If low, add the manufacturer-recommended oil type (e.g., 0W-20) until the level is correct.

3. Replace Oil Filter

• Tools Required: Oil filter wrench, drain pan, socket set.
• Sub-steps:
  1. Place a drain pan under the oil filter.
  2. Use the oil filter wrench to remove the old oil filter.

  4. Install the new filter by hand until snug, then tighten as per manufacturer specifications.

4. Replace Engine Oil

• Tools Required: Socket set, funnel, oil drain pan.
• Sub-steps:
  1. Remove the oil drain plug using a socket set and let the old oil drain into the pan.
  2. Replace the drain plug and tighten it to the recommended torque specifications.
  3. Use a funnel to add new oil through the oil filler cap.

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