Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check and Top Off Oil Level

Remove the oil dipstick and clean it with a rag.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate grade of oil as specified in the owner’s manual. Use a funnel to prevent spills.

3. Replace Oil Filter

Tools Required: Oil filter wrench, socket set, and drain pan.
Place the drain pan under the oil filter.
Use the oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the gasket of the new filter.
Install the new oil filter by hand, tightening it securely.

4. Replace Oil Pressure Sending Unit

Tools Required: Socket set, torque wrench.
Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector from the sending unit.
Unscrew the old sending unit using a socket wrench.
Install the new sending unit and torque it to the manufacturer's specifications (typically around 15-20 ft-lbs).
Reconnect the electrical connector.

5. Test Oil Pressure

Tools Required: Oil pressure gauge.
Remove the oil pressure sending unit and install the oil pressure gauge in its place.
Start the engine and observe the pressure readings; they should be within normal range (typically 25-65 psi at idle).
If readings are normal, turn off the engine and replace the sending unit.
