Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and allow the engine to cool.
Disconnect the battery to prevent electrical shorts.

2. Check Oil Level

Remove the dipstick and wipe it clean with a lint-free cloth.
Reinsert the dipstick and remove it to check the oil level.
If low, add the correct type of oil as specified in the owner's manual (usually 0W-20 or 5W-20 for Honda CR-V).

3. Replace Oil Filter (if necessary)

Use an oil filter wrench to remove the old oil filter.
Ensure the rubber O-ring from the old filter is not stuck on the engine.
Apply a thin layer of new oil to the O-ring of the new filter.
Install the new oil filter and tighten it according to the manufacturer’s specifications.

4. Inspect and Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, usually near the oil filter or on the engine block.
Disconnect the electrical connector and remove the unit using a socket wrench.
Install the new oil pressure sending unit, ensuring it is tightened securely.
Reconnect the electrical connector.

5. Check and Replace Oil Pump (if needed)

Remove the oil pan by draining the oil completely.
Detach the oil pump from the engine block (may require removing the timing cover).
Inspect the oil pump for wear and replace it if necessary.
Reinstall the oil pump and oil pan, ensuring a proper seal to prevent leaks.

6. Refill Engine Oil

After all repairs, refill the engine with the appropriate type and amount of oil.
Start the engine and check for leaks around the oil filter and oil pressure sending unit.
