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 Replace Engine Oil

Tools Required: Socket set, oil filter wrench, funnel, oil catch pan
Drain the old engine oil by removing the oil drain plug. Allow oil to fully drain into the catch pan.
Remove the old oil filter using the oil filter wrench. Ensure the rubber gasket comes off with it.
Install a new oil filter, lubricating the gasket with a bit of new oil to ensure a good seal.
Reinstall the oil drain plug and torque it to the manufacturer’s specifications (typically around 20 Nm).
Fill the engine with the recommended type and amount of new oil (refer to the owner's manual).

3. Inspect and Replace Oil Pressure Sending Unit

Tools Required: Socket set, torque wrench
Locate the oil pressure sending unit, typically found near the oil filter.
Disconnect the electrical connector and remove the sending unit using a socket wrench.
Install the new oil pressure sending unit and torque it to manufacturer specifications (generally around 15 Nm).
Reconnect the electrical connector.

4. Mechanical Oil Pressure Test

Tools Required: Mechanical oil pressure gauge
Remove the oil pressure sending unit and install the mechanical gauge.
Start the engine and observe the oil pressure reading. It should meet manufacturer specifications (usually around 20-60 psi at idle).
If pressure is low, further investigation into the oil pump or internal engine issues may be necessary.

5. Reassemble and Finalize

Reconnect the negative battery terminal.
Start the engine and check for any leaks around the oil filter and sending unit.
Monitor oil pressure warning light status.
