Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery to avoid any electrical shorts.

2. Check Oil Level

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 and viscosity of oil as per the owner's manual.

3. Inspect and Replace Oil Pressure Sending Unit

Locate the oil pressure sending unit, typically found near the oil filter.
Disconnect the electrical connector from the sending unit.
Use a socket wrench to remove the sending unit.
Install the new sending unit, ensuring it is tightened to the manufacturer's specifications (usually around 12-15 ft-lbs).
Reconnect the electrical connector.

4. Replace Engine Oil and Filter

Place an oil drain pan under the oil pan.
Remove the oil drain plug and let the old oil drain completely.
Replace the drain plug and torque to manufacturer specifications (typically around 20-30 ft-lbs).
Remove the old oil filter using an oil filter wrench.
Apply a small amount of new oil to the rubber gasket of the new filter, then install it.
Add the new engine oil through the oil filler cap, using the recommended type and quantity.

5. Final Checks

Reconnect the battery.
Start the engine and allow it to idle for a few minutes.
Monitor the oil pressure light and check for leaks around the oil filter and drain plug.
