Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety.

2. Change Engine Oil

Sub-step 1: Drain the old oil by removing the oil drain plug and allowing it to fully drain into a container. Use a socket set.
Sub-step 2: Replace the oil filter using an oil filter wrench.
Sub-step 3: Reinstall the oil drain plug and torque it to the manufacturer’s specified value.
Sub-step 4: Fill the engine with new oil (consult the owner’s manual for the correct oil type and capacity).

3. Replace Oil Pressure Sending Unit (if faulty)

Sub-step 1: Locate the oil pressure sending unit on the engine.
Sub-step 2: Disconnect the electrical connector and unscrew the unit using the appropriate wrench.
Sub-step 3: Install the new oil pressure sending unit and reconnect the electrical connector.
Sub-step 4: Ensure the unit is securely fastened but do not overtighten.

4. Test Oil Pressure

Sub-step 1: Install a mechanical oil pressure gauge in place of the oil pressure sending unit.
Sub-step 2: Start the engine and observe the oil pressure reading; refer to specifications for acceptable values.
Sub-step 3: If pressure is still low, further investigation into the oil pump and oil passages may be necessary.
