Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check Engine Oil Level

Remove the dipstick, wipe it clean, and reinsert it.
Remove it again and check the oil level; add oil if below the minimum mark.

3. Inspect and Replace the Oil Pressure Sending Unit

Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector and unscrew the sending unit using a socket.
Install the new sending unit by reversing the removal process and tightening to the manufacturer’s torque specification (consult the repair manual).

4. Change Engine Oil and Filter

Drain the old oil by removing the oil drain plug; allow it to fully drain into a pan.
Replace the oil filter with a new one, using an oil filter wrench.
Reinstall the drain plug and torque it to the specified value.
Fill the engine with new oil that meets manufacturer specifications (typically 5W-30 or 0W-20).

5. Check for Leaks

Start the engine and allow it to idle.
Observe the oil pressure gauge and check for leaks around the oil filter and sending unit.
If no leaks are present and oil pressure is normal, proceed.
