Solution

1. Preparation

Gather tools: OBD-II scanner, mechanical oil pressure gauge, socket set, torque wrench, and oil filter wrench.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Top Off Engine Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate type of engine oil specified in the owner's manual.
Start the engine and check for any leaks around the oil filter and drain plug.

3. Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector from the sending unit.
Use a socket wrench to remove the old sending unit.
Install the new sending unit and torque it to the manufacturer’s specification.
Reconnect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Drain the engine oil and remove the oil pan using a socket set.
Detach the oil pump from the engine block by removing the mounting bolts.
Inspect the oil pump for wear or damage; replace if necessary.
Reinstall the new oil pump, ensuring it is properly aligned and secured.
Reattach the oil pan and torque the bolts to specification.

5. Refill Engine Oil

Refill the engine with the correct type and amount of oil as per the manufacturer's specifications.
Start the engine and allow it to run for a few minutes, checking for leaks.
