3. Replace the oil filter with a new one, ensuring the old filter's O-ring is removed.
4. Refill the engine with the manufacturer-recommended oil type and capacity (refer to the owner's manual).

Tools Required:

Oil drain pan
Socket set (for oil filter removal)
Oil filter wrench
Funnel

3. Replace Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit, typically found near the oil filter.
2. Disconnect the electrical connector from the sending unit.
3. Use a socket or wrench to remove the sending unit.
4. Install the new sending unit and reconnect the electrical connector.
5. Check for any leaks around the new sending unit.

Tools Required:
