Solution

1. Preparation

Gather tools such as an OBD-II scanner, mechanical oil pressure gauge, socket set, and oil change supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Top Off Oil Level

Remove the dipstick, wipe it clean, reinsert it, and remove it again to check the oil level.
If the oil level is low, add the appropriate type of oil as specified in the owner’s manual until the correct level is reached.

3. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector and remove the unit using a socket.
Install the new oil pressure sending unit and reconnect the electrical connector.
Torque the new unit to the manufacturer's specifications (typically around 15-20 ft-lbs).

4. Change Engine Oil and Filter

Remove the oil drain plug and drain the old oil into a suitable container.
Replace the oil filter with a new one, ensuring the rubber gasket is lubricated.
Reinstall the drain plug and torque it to specifications (usually around 20-25 ft-lbs).
Add the appropriate new oil to the engine through the oil filler cap.

5. Test Oil Pressure

Install a mechanical oil pressure gauge at the oil pressure sending unit location.
Start the engine and observe the oil pressure reading. It should be within the manufacturer's specified range (typically 20-60 PSI at idle).
If pressure is still low, further investigation of the oil pump and internal engine components may be necessary.
