Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical issues during repairs.

2. Change Engine Oil and Filter

Lift the Vehicle: Use a jack and jack stands to raise the vehicle safely.
Drain Oil:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug using a socket set and allow the oil to fully drain.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Apply a small amount of new oil to the rubber gasket of the new filter.
- Install the new oil filter and tighten according to manufacturer specifications (usually hand-tight).
Refill Oil:
- Replace the drain plug and tighten to the recommended torque (typically 25 Nm).
- Pour the recommended type and amount of new engine oil into the engine (check owner's manual for specifications).

3. Replace Oil Pressure Sending Unit (if faulty)

Locate the Sending Unit: Identify the oil pressure sending unit, usually located near the oil filter or on the engine block.
Disconnect Electrical Connector: Carefully unplug the electrical connector from the sending unit.
Remove Sending Unit: Use a socket wrench to unscrew and remove the sending unit.
Install New Sending Unit: Apply Teflon tape to the threads of the new sending unit and install it in the same location, tightening to the manufacturer’s specifications.
Reconnect Electrical Connector: Plug the electrical connector back into the new sending unit.

4. Check for Leaks

Start the engine and let it idle while monitoring for any oil leaks around the oil filter and sending unit.
Check the oil pressure gauge to ensure it is within normal operating range.
