Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and safe to work on.
Disconnect the battery to prevent any electrical issues.

2. Check and Top-Up Oil

Remove the oil filler cap.
Using a funnel, add the appropriate type and grade of oil if the level is low.
Replace the oil filler cap securely.

3. Replace Oil Filter

Locate the oil filter; use an oil filter wrench to remove it.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter and tighten it by hand until snug, then give it a slight additional turn.

4. Inspect and Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, typically near the oil filter or on the engine block.
Disconnect the electrical connector and unscrew the sending unit using a socket.
Install the new sending unit, ensuring it is tightened to the manufacturer’s specifications (usually around 15-20 ft-lbs).
Reconnect the electrical connector.

5. Test Oil Pressure

Connect a mechanical oil pressure gauge to the oil pressure sending unit’s port.
Start the engine and monitor the oil pressure reading on the gauge.
If pressure is within normal operating range (typically 25-65 psi at idle), proceed to the next step.
If not, further investigation into engine internals may be necessary.
