3. Replace the oil filter with a new one.
4. Refill with the correct type and amount of engine oil as specified in the owner’s manual.
5. Replace the oil fill cap and start the engine, allowing it to run for a few minutes to circulate the new oil.

3. Inspect and Replace the Oil Pressure Sending Unit

Tools Required: Socket set, torque wrench, screwdriver.
Sub-steps:
1. Locate the oil pressure sending unit, typically found near the oil filter or on the engine block.
2. Disconnect the electrical connector from the sending unit.
3. Remove the sending unit using the appropriate socket.
4. Install the new sending unit, ensuring it is torqued to the manufacturer’s specification.
5. Reconnect the electrical connector and check for tightness.

4. Test the Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan if oil pump replacement is necessary.
2. Inspect the oil pump for wear or damage.
