Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off and cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Change Engine Oil and Filter

Tools Required: Socket set, oil filter wrench, oil catch pan, funnel.
Remove the oil drain plug and allow old oil to completely drain into the catch pan.
Replace the oil drain plug and tighten to manufacturer specifications (typically 20-25 Nm).
Remove the old oil filter using an oil filter wrench.
Apply a thin layer of new oil to the rubber gasket of the new oil filter and install it, tightening by hand.
Refill the engine with new oil using the recommended type and quantity (usually 5W-30 or as specified in the owner's manual).

3. Replace Oil Pressure Sending Unit

Tools Required: Socket set, wrench set, oil catch pan (for potential spills).
Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector from the sending unit.
Use a socket to carefully remove the oil pressure sending unit from the engine block.
Install the new oil pressure sending unit and tighten to specifications (generally hand-tight plus a quarter turn).
Reconnect the electrical connector.

4. Inspect and Test Oil Pump (if necessary)

Tools Required: Socket set, torque wrench, oil pressure gauge.
If oil pressure is still low after the above steps, remove the oil pan to access the oil pump.
Inspect the oil pump for wear, cracks, or damage, and replace if necessary.
Reinstall the oil pan with a new gasket using a torque wrench to the specified torque (usually 10-15 Nm).
Start the engine and test oil pressure with a mechanical gauge to ensure it is within the manufacturer’s specifications.
