Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is on a level surface with the engine off and cool.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Engine Oil

Remove the engine oil fill cap.
If the oil level is low, add the appropriate type and grade of oil as specified in the owner’s manual.
If the oil is dirty or hasn’t been changed in over 5,000 miles, proceed to change the oil.
- Drain the old oil by removing the oil drain plug.
- Replace the oil filter using an oil filter wrench.
- Reinstall the oil drain plug and tighten it to the manufacturer’s specifications (usually around 20-30 lb-ft).
- Fill the engine with new oil through the oil fill cap.

3. Inspect and Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, typically situated near the oil filter or near the engine block.
Disconnect the electrical connector from the sending unit.
Use a socket wrench to remove the sending unit.
Install the new oil pressure sending unit and tighten it to the specified torque (usually around 15-20 lb-ft).
Reconnect the electrical connector.

4. Test Oil Pressure

Reconnect the negative battery terminal.
Start the engine and let it idle.
Check the oil pressure using a mechanical gauge to ensure it is within the manufacturer’s specified range.
