Remove the oil fill cap on the engine.
Use a funnel to add the appropriate type and amount of oil as specified in the owner’s manual.
Replace the oil fill cap securely.

3. Replace Oil Pressure Sending Unit

Tools Required: Socket set, torque wrench, oil catch pan.
Locate the oil pressure sending unit (typically found near the oil filter or on the engine block).
Disconnect the electrical connector from the sending unit.
Using the socket set, remove the old sending unit and discard it.
Apply a small amount of thread sealant to the threads of the new sending unit.
Install the new sending unit and torque it to the manufacturer’s specifications.
Reconnect the electrical connector.

4. Check for Leaks

Start the engine and allow it to reach normal operating temperature.
Check around the oil pressure sending unit and oil lines for any signs of leaks.
If leaks are present, tighten connections or replace gaskets/seals as necessary.

5. Reconnect Battery and Clear Codes

Reconnect the battery.
Use the OBD-II scanner to clear any error codes and reset the check engine light if applicable.
